Introduction MII51001-1.8 Introduction The MAX® II family of instant-on, non-volatile CPLDs is based on a 0.18-µm, 6-layermetal-flash process, with densities from 240 to 2,210 logic elements (LEs) (128 to 2,210 equivalent macrocells) and non-volatile storage of 8 Kbits. MAX II devices offer high I/O counts, fast performance, and reliable fitting versus other CPLD architectures. Featuring MultiVolt core, a user flash memory (UFM) block, and enhanced in-system programmability (ISP), MAX II devices are designed to reduce cost and power while providing programmable solutions for applications such as bus bridging, I/O expansion, power-on reset (POR) and sequencing control, and device configuration control.

MAX II devices support vertical migration within the same package (for example, you can migrate between the EPM570, EPM1270, and EPM2210 devices in the 256-pin FineLine BGA package). Vertical migration means that you can migrate to devices whose dedicated pins and JTAG pins are the same and power pins are subsets or supersets for a given package across device densities. The largest density in any package has the highest number of power pins; you must lay out for the largest planned density in a package to provide the necessary power pins for migration. For I/O pin migration across densities, cross reference the available I/O pins using the device pin-outs for all planned densities of a given package type to identify which I/O pins can be migrated. The Quartus® II software can automatically cross-reference and place all pins for you when given a device migration list. Table 1–3.

MAX IIG and MAX IIZ devices only accept 1.8 V as the external supply voltage. MAX IIZ devices are pin-compatible with MAX IIG devices in the 100-pin Micro FineLine BGA and 256-pin Micro FineLine BGA packages. Except for external supply voltage requirements, MAX II and MAX II G devices have identical pin-outs and timing specifications.

MAX II Architecture MII51002-2.2 Introduction This chapter describes the architecture of the MAX II device and contains the following sections: ■ ■ ■ ■ ■ ■ ■ ■ “Functional Description” on page 2–1 “Logic Array Blocks” on page 2–4 “Logic Elements” on page 2–6 “MultiTrack Interconnect” on page 2–12 “Global Signals” on page 2–16 “User Flash Memory Block” on page 2–18 “MultiVolt Core” on page 2–22 “I/O Structure” on page 2–23 Functional Description MAX® II devices contain a two-dimensional row- and column-based architecture to implement custom logic. Row and column interconnects provide signal interconnects between the logic array blocks (LABs). The logic array consists of LABs, with 10 logic elements (LEs) in each LAB. An LE is a small unit of logic providing efficient implementation of user logic functions. LABs are grouped into rows and columns across the device. The MultiTrack interconnect provides fast granular timing delays between LABs. The fast routing between LEs provides minimum timing delay for added levels of logic versus globally routed interconnect structures. The MAX II device I/O pins are fed by I/O elements (IOE) located at the ends of LAB rows and columns around the periphery of the device. Each IOE contains a bidirectional I/O buffer with several advanced features. I/O pins support Schmitt trigger inputs and various single-ended standards, such as 66-MHz, 32-bit PCI, and LVTTL. MAX II devices provide a global clock network. The global clock network consists of four global clock lines that drive throughout the entire device, providing clocks for all resources within the device. The global clock lines can also be used for control signals such as clear, preset, or output enable. © October 2008 Altera Corporation MAX II Device Handbook 2–2 Chapter 2: MAX II Architecture Functional Description Figure 2–1 shows a functional block diagram of the MAX II device.

On the EPM240 device, this block is located on the left side of the device. On the EPM570, EPM1270, and EPM2210 devices, the flash memory block is located on the bottom-left area of the device. The majority of this flash memory storage is partitioned as the dedicated configuration flash memory (CFM) block. The CFM block provides the nonvolatile storage for all of the SRAM configuration information. The CFM automatically downloads and configures the logic and I/O at power-up, providing instant-on operation. f For more information about configuration upon power-up, refer to the Hot Socketing and Power-On Reset in MAX II Devices chapter in the MAX II Device Handbook. A portion of the flash memory within the MAX II device is partitioned into a small block for user data. This user flash memory (UFM) block provides 8,192 bits of general-purpose user storage. The UFM provides programmable port connections to the logic array for reading and writing. There are three LAB rows adjacent to this block, with column numbers varying by device. Table 2–1 shows the number of LAB rows and columns in each device, as well as the number of LAB rows and columns adjacent to the flash memory area in the EPM570, EPM1270, and EPM2210 devices. The long LAB rows are full LAB rows that extend from one side of row I/O blocks to the other. The short LAB rows are adjacent to the UFM block; their length is shown as width in LAB columns.

There are 26 possible unique inputs into an LAB, with an additional 10 local feedback input lines fed by LE outputs in the same LAB. The local interconnect transfers signals between LEs in the same LAB. LUT chain connections transfer the output of one LE’s LUT to the adjacent LE for fast sequential LUT connections within the same LAB. Register chain connections transfer the output of one LE’s register to the adjacent LE’s register within an LAB. The Quartus® II software places associated logic within an LAB or adjacent LABs, allowing the use of local, LUT chain, and register chain connections for performance and area efficiency. Figure 2–3 shows the MAX II LAB. Figure 2–3.

LAB Interconnects The LAB local interconnect can drive LEs within the same LAB. The LAB local interconnect is driven by column and row interconnects and LE outputs within the same LAB. Neighboring LABs, from the left and right, can also drive an LAB’s local interconnect through the DirectLink connection. The DirectLink connection feature minimizes the use of row and column interconnects, providing higher performance and flexibility. Each LE can drive 30 other LEs through fast local and DirectLink interconnects. Figure 2–4 shows the DirectLink connection. MAX II Device Handbook © October 2008 Altera Corporation Chapter 2: MAX II Architecture Logic Array Blocks 2–5 Figure 2–4. DirectLink Connection DirectLink interconnect from left LAB or IOE output DirectLink interconnect from right LAB or IOE output LE0 LE1 LE2 LE3 LE4 DirectLink interconnect to left Local Interconnect LE5 LE6 LE7 LE8 LE9 Logic Element LAB DirectLink interconnect to right LAB Control Signals Each LAB contains dedicated logic for driving control signals to its LEs. The control signals include two clocks, two clock enables, two asynchronous clears, a synchronous clear, an asynchronous preset/load, a synchronous load, and add/subtract control signals, providing a maximum of 10 control signals at a time. Although synchronous load and clear signals are generally used when implementing counters, they can also be used with other functions. Each LAB can use two clocks and two clock enable signals. Each LAB’s clock and clock enable signals are linked. For example, any LE in a particular LAB using the labclk1 signal also uses labclkena1. If the LAB uses both the rising and falling edges of a clock, it also uses both LAB-wide clock signals. Deasserting the clock enable signal turns off the LAB-wide clock. Each LAB can use two asynchronous clear signals and an asynchronous load/preset signal. By default, the Quartus II software uses a NOT gate push-back technique to achieve preset. If you disable the NOT gate push-back option or assign a given register to power-up high using the Quartus II software, the preset is then achieved using the asynchronous load signal with asynchronous load data input tied high. With the LAB-wide addnsub control signal, a single LE can implement a one-bit adder and subtractor. This saves LE resources and improves performance for logic functions such as correlators and signed multipliers that alternate between addition and subtraction depending on data. The LAB column clocks [3..0], driven by the global clock network, and LAB local interconnect generate the LAB-wide control signals. The MultiTrack interconnect structure drives the LAB local interconnect for non-global control signal generation. The MultiTrack interconnect’s inherent low skew allows clock and control signal distribution in addition to data. Figure 2–5 shows the LAB control signal generation circuit. © October 2008 Altera Corporation MAX II Device Handbook 2–6 Chapter 2: MAX II Architecture Logic Elements Figure 2–5.

Each LE contains a four-input LUT, which is a function generator that can implement any function of four variables. In addition, each LE contains a programmable register and carry chain with carry-select capability. A single LE also supports dynamic single-bit addition or subtraction mode selectable by an LAB-wide control signal. Each LE drives all types of interconnects: local, row, column, LUT chain, register chain, and DirectLink interconnects. See Figure 2–6.

Each register has data, true asynchronous load data, clock, clock enable, clear, and asynchronous load/preset inputs. Global signals, general-purpose I/O pins, or any LE can drive the register’s clock and clear control signals. Either general-purpose I/O pins or LEs can drive the clock enable, preset, asynchronous load, and asynchronous data. The asynchronous load data input comes from the data3 input of the LE. For combinational functions, the LUT output bypasses the register and drives directly to the LE outputs. Each LE has three outputs that drive the local, row, and column routing resources. The LUT or register output can drive these three outputs independently. Two LE outputs drive column or row and DirectLink routing connections and one drives local interconnect resources. This allows the LUT to drive one output while the register drives another output. This register packing feature improves device utilization because the device can use the register and the LUT for unrelated functions. Another special packing mode allows the register output to feed back into the LUT of the same LE so that the register is packed with its own fan-out LUT. This provides another mechanism for improved fitting. The LE can also drive out registered and unregistered versions of the LUT output. © October 2008 Altera Corporation MAX II Device Handbook 2–8 Chapter 2: MAX II Architecture Logic Elements LUT Chain and Register Chain In addition to the three general routing outputs, the LEs within an LAB have LUT chain and register chain outputs. LUT chain connections allow LUTs within the same LAB to cascade together for wide input functions. Register chain outputs allow registers within the same LAB to cascade together. The register chain output allows an LAB to use LUTs for a single combinational function and the registers to be used for an unrelated shift register implementation. These resources speed up connections between LABs while saving local interconnect resources. Refer to “MultiTrack Interconnect” on page 2–12 for more information about LUT chain and register chain connections. addnsub Signal The LE’s dynamic adder/subtractor feature saves logic resources by using one set of LEs to implement both an adder and a subtractor. This feature is controlled by the LAB-wide control signal addnsub. The addnsub signal sets the LAB to perform either A + B or A – B. The LUT computes addition; subtraction is computed by adding the two’s complement of the intended subtractor. The LAB-wide signal converts to two’s complement by inverting the B bits within the LAB and setting carry-in to 1, which adds one to the least significant bit (LSB). The LSB of an adder/subtractor must be placed in the first LE of the LAB, where the LAB-wide addnsub signal automatically sets the carry-in to 1. The Quartus II Compiler automatically places and uses the adder/subtractor feature when using adder/subtractor parameterized functions. LE Operating Modes The MAX II LE can operate in one of the following modes: ■ ■ “Normal Mode” “Dynamic Arithmetic Mode” Each mode uses LE resources differently. In each mode, eight available inputs to the LE, the four data inputs from the LAB local interconnect, carry-in0 and carryin1 from the previous LE, the LAB carry-in from the previous carry-chain LAB, and the register chain connection are directed to different destinations to implement the desired logic function. LAB-wide signals provide clock, asynchronous clear, asynchronous preset/load, synchronous clear, synchronous load, and clock enable control for the register. These LAB-wide signals are available in all LE modes. The addnsub control signal is allowed in arithmetic mode. The Quartus II software, in conjunction with parameterized functions such as library of parameterized modules (LPM) functions, automatically chooses the appropriate mode for common functions such as counters, adders, subtractors, and arithmetic functions. MAX II Device Handbook © October 2008 Altera Corporation Chapter 2: MAX II Architecture Logic Elements 2–9 Normal Mode The normal mode is suitable for general logic applications and combinational functions. In normal mode, four data inputs from the LAB local interconnect are inputs to a four-input LUT (see Figure 2–7). The Quartus II Compiler automatically selects the carry-in or the data3 signal as one of the inputs to the LUT. Each LE can use LUT chain connections to drive its combinational output directly to the next LE in the LAB. Asynchronous load data for the register comes from the data3 input of the LE. LEs in normal mode support packed registers. Figure 2–7.

Dynamic Arithmetic Mode The dynamic arithmetic mode is ideal for implementing adders, counters, accumulators, wide parity functions, and comparators. An LE in dynamic arithmetic mode uses four 2-input LUTs configurable as a dynamic adder/subtractor. The first two 2-input LUTs compute two summations based on a possible carry-in of 1 or 0; the other two LUTs generate carry outputs for the two chains of the carry-select circuitry. As shown in Figure 2–8, the LAB carry-in signal selects either the carry-in0 or carry-in1 chain. The selected chain’s logic level in turn determines which parallel sum is generated as a combinational or registered output. For example, when implementing an adder, the sum output is the selection of two possible calculated sums: data1 + data2 + carry in0 or data1 + data2 + carry-in1 © October 2008 Altera Corporation MAX II Device Handbook 2–10 Chapter 2: MAX II Architecture Logic Elements The other two LUTs use the data1 and data2 signals to generate two possible carry-out signals: one for a carry of 1 and the other for a carry of 0. The carry-in0 signal acts as the carry-select for the carry-out0 output and carry-in1 acts as the carryselect for the carry-out1 output. LEs in arithmetic mode can drive out registered and unregistered versions of the LUT output. The dynamic arithmetic mode also offers clock enable, counter enable, synchronous up/down control, synchronous clear, synchronous load, and dynamic adder/subtractor options. The LAB local interconnect data inputs generate the counter enable and synchronous up/down control signals. The synchronous clear and synchronous load options are LAB-wide signals that affect all registers in the LAB. The Quartus II software automatically places any registers that are not used by the counter into other LABs. The addnsub LAB-wide signal controls whether the LE acts as an adder or subtractor.

Carry-Select Chain The carry-select chain provides a very fast carry-select function between LEs in dynamic arithmetic mode. The carry-select chain uses the redundant carry calculation to increase the speed of carry functions. The LE is configured to calculate outputs for a possible carry-in of 0 and carry-in of 1 in parallel. The carry-in0 and carry-in1 signals from a lower-order bit feed forward into the higher-order bit via the parallel carry chain and feed into both the LUT and the next portion of the carry chain. Carryselect chains can begin in any LE within an LAB. MAX II Device Handbook © October 2008 Altera Corporation Chapter 2: MAX II Architecture Logic Elements 2–11 The speed advantage of the carry-select chain is in the parallel precomputation of carry chains. Since the LAB carry-in selects the precomputed carry chain, not every LE is in the critical path. Only the propagation delays between LAB carry-in generation (LE 5 and LE 10) are now part of the critical path. This feature allows the MAX II architecture to implement high-speed counters, adders, multipliers, parity functions, and comparators of arbitrary width. Figure 2–9 shows the carry-select circuitry in an LAB for a 10-bit full adder. One portion of the LUT generates the sum of two bits using the input signals and the appropriate carry-in bit; the sum is routed to the output of the LE. The register can be bypassed for simple adders or used for accumulator functions. Another portion of the LUT generates carry-out bits. An LAB-wide carry-in bit selects which chain is used for the addition of given inputs. The carry-in signal for each chain, carry-in0 or carry-in1, selects the carry-out to carry forward to the carry-in signal of the nexthigher-order bit. The final carry-out signal is routed to an LE, where it is fed to local, row, or column interconnects. Figure 2–9.

Parameterized functions such as LPM functions automatically take advantage of carry chains for the appropriate functions. The Quartus II software creates carry chains longer than 10 LEs by linking adjacent LABs within the same row together automatically. A carry chain can extend horizontally up to one full LAB row, but does not extend between LAB rows. Clear and Preset Logic Control LAB-wide signals control the logic for the register’s clear and preset signals. The LE directly supports an asynchronous clear and preset function. The register preset is achieved through the asynchronous load of a logic high. MAX II devices support simultaneous preset/asynchronous load and clear signals. An asynchronous clear signal takes precedence if both signals are asserted simultaneously. Each LAB supports up to two clears and one preset signal. In addition to the clear and preset ports, MAX II devices provide a chip-wide reset pin (DEV_CLRn) that resets all registers in the device. An option set before compilation in the Quartus II software controls this pin. This chip-wide reset overrides all other control signals and uses its own dedicated routing resources (that is, it does not use any of the four global resources). Driving this signal low before or during power-up prevents user mode from releasing clears within the design. This allows you to control when clear is released on a device that has just been powered-up. If not set for its chipwide reset function, the DEV_CLRn pin is a regular I/O pin. By default, all registers in MAX II devices are set to power-up low. However, this power-up state can be set to high on individual registers during design entry using the Quartus II software. MultiTrack Interconnect In the MAX II architecture, connections between LEs, the UFM, and device I/O pins are provided by the MultiTrack interconnect structure. The MultiTrack interconnect consists of continuous, performance-optimized routing lines used for inter- and intradesign block connectivity. The Quartus II Compiler automatically places critical design paths on faster interconnects to improve design performance. The MultiTrack interconnect consists of row and column interconnects that span fixed distances. A routing structure with fixed length resources for all devices allows predictable and short delays between logic levels instead of large delays associated with global or long routing lines. Dedicated row interconnects route signals to and from LABs within the same row. These row resources include: ■ ■ DirectLink interconnects between LABs R4 interconnects traversing four LABs to the right or left The DirectLink interconnect allows an LAB to drive into the local interconnect of its left and right neighbors. The DirectLink interconnect provides fast communication between adjacent LABs and/or blocks without using row interconnect resources. MAX II Device Handbook © October 2008 Altera Corporation Chapter 2: MAX II Architecture MultiTrack Interconnect 2–13 The R4 interconnects span four LABs and are used for fast row connections in a fourLAB region. Every LAB has its own set of R4 interconnects to drive either left or right. Figure 2–10 shows R4 interconnect connections from an LAB. R4 interconnects can drive and be driven by row IOEs. For LAB interfacing, a primary LAB or horizontal LAB neighbor can drive a given R4 interconnect. For R4 interconnects that drive to the right, the primary LAB and right neighbor can drive on to the interconnect. For R4 interconnects that drive to the left, the primary LAB and its left neighbor can drive on to the interconnect. R4 interconnects can drive other R4 interconnects to extend the range of LABs they can drive. R4 interconnects can also drive C4 interconnects for connections from one row to another. Figure 2–10.

(2) This pattern is repeated for every LAB in the LAB row. The column interconnect operates similarly to the row interconnect. Each column of LABs is served by a dedicated column interconnect, which vertically routes signals to and from LABs and row and column IOEs. These column resources include: ■ ■ ■ LUT chain interconnects within an LAB Register chain interconnects within an LAB C4 interconnects traversing a distance of four LABs in an up and down direction MAX II devices include an enhanced interconnect structure within LABs for routing LE output to LE input connections faster using LUT chain connections and register chain connections. The LUT chain connection allows the combinational output of an LE to directly drive the fast input of the LE right below it, bypassing the local interconnect. These resources can be used as a high-speed connection for wide fan-in © October 2008 Altera Corporation MAX II Device Handbook 2–14 Chapter 2: MAX II Architecture MultiTrack Interconnect functions from LE 1 to LE 10 in the same LAB. The register chain connection allows the register output of one LE to connect directly to the register input of the next LE in the LAB for fast shift registers. The Quartus II Compiler automatically takes advantage of these resources to improve utilization and performance. Figure 2–11 shows the LUT chain and register chain interconnects. Figure 2–11.

Every LAB has its own set of C4 interconnects to drive either up or down. Figure 2–12 shows the C4 interconnect connections from an LAB in a column. The C4 interconnects can drive and be driven by column and row IOEs. For LAB interconnection, a primary LAB or its vertical LAB neighbor can drive a given C4 interconnect. C4 interconnects can drive each other to extend their range as well as drive row interconnects for columnto-column connections.

The UFM block connects to row and column interconnects and has local interconnect regions driven by row and column interconnects. This block also has DirectLink interconnects for fast connections to and from a neighboring LAB.

These four pins can also be used as generalpurpose I/O if they are not used to drive the global clock network. The four global clock lines in the global clock network drive throughout the entire device. The global clock network can provide clocks for all resources within the device including LEs, LAB local interconnect, IOEs, and the UFM block. The global clock lines can also be used for global control signals, such as clock enables, synchronous or asynchronous clears, presets, output enables, or protocol control signals such as TRDY and IRDY for PCI. Internal logic can drive the global clock network for internally-generated global clocks and control signals. Figure 2–13 shows the various sources that drive the global clock network.

The global clock network drives to individual LAB column signals, LAB column clocks [3..0], that span an entire LAB column from the top to the bottom of the device. Unused global clocks or control signals in a LAB column are turned off at the LAB column clock buffers shown in Figure 2–14. The LAB column clocks [3..0] are multiplexed down to two LAB clock signals and one LAB clear signal. Other control signal types route from the global clock network into the LAB local interconnect.

User Flash Memory Block MAX II devices feature a single UFM block, which can be used like a serial EEPROM for storing non-volatile information up to 8,192 bits. The UFM block connects to the logic array through the MultiTrack interconnect, allowing any LE to interface to the UFM block. Figure 2–15 shows the UFM block and interface signals. The logic array is used to create customer interface or protocol logic to interface the UFM block data outside of the device. The UFM block offers the following features: ■ ■ ■ ■ Non-volatile storage up to 16-bit wide and 8,192 total bits Two sectors for partitioned sector erase Built-in internal oscillator that optionally drives logic array Program, erase, and busy signals MAX II Device Handbook © October 2008 Altera Corporation Chapter 2: MAX II Architecture User Flash Memory Block 2–19 ■ ■ Auto-increment addressing Serial interface to logic array with programmable interface Figure 2–15.

Table 2–3 shows the data size, sector, and address sizes for the UFM block. Table 2–3. UFM Array Size Device EPM240 EPM570 EPM1270 EPM2210 Total Bits 8,192 Sectors 2 (4,096 bits/sector) Address Bits 9 Data Width 16 There are 512 locations with 9-bit addressing ranging from 000h to 1FFh. Sector 0 address space is 000h to 0FFh and Sector 1 address space is from 100h to 1FFh. The data width is up to 16 bits of data. The Quartus II software automatically creates logic to accommodate smaller read or program data widths. Erasure of the UFM involves individual sector erasing (that is, one erase of sector 0 and one erase of sector 1 is required to erase the entire UFM block). Since sector erase is required before a program or write, having two sectors enables a sector size of data to be left untouched while the other sector is erased and programmed with new data. © October 2008 Altera Corporation MAX II Device Handbook 2–20 Chapter 2: MAX II Architecture User Flash Memory Block Internal Oscillator As shown in Figure 2–15, the dedicated circuitry within the UFM block contains an oscillator. The dedicated circuitry uses this internally for its read and program operations. This oscillator's divide by 4 output can drive out of the UFM block as a logic interface clock source or for general-purpose logic clocking. The typical OSC output signal frequency ranges from 3.3 to 5.5 MHz, and its exact frequency of operation is not programmable. Program, Erase, and Busy Signals The UFM block’s dedicated circuitry automatically generates the necessary internal program and erase algorithm once the PROGRAM or ERASE input signals have been asserted. The PROGRAM or ERASE signal must be asserted until the busy signal deasserts, indicating the UFM internal program or erase operation has completed. The UFM block also supports JTAG as the interface for programming and/or reading. f For more information about programming and erasing the UFM block, refer to the Using User Flash Memory in MAX II Devices chapter in the MAX II Device Handbook. Auto-Increment Addressing The UFM block supports standard read or stream read operations. The stream read is supported with an auto-increment address feature. Deasserting the ARSHIFT signal while clocking the ARCLK signal increments the address register value to read consecutive locations from the UFM array. Serial Interface The UFM block supports a serial interface with serial address and data signals. The internal shift registers within the UFM block for address and data are 9 bits and 16 bits wide, respectively. The Quartus II software automatically generates interface logic in LEs for a parallel address and data interface to the UFM block. Other standard protocol interfaces such as SPI are also automatically generated in LE logic by the Quartus II software. f For more information about the UFM interface signals and the Quartus II LE-based alternate interfaces, refer to the Using User Flash Memory in MAX II Devices chapter in the MAX II Device Handbook. UFM Block to Logic Array Interface The UFM block is a small partition of the flash memory that contains the CFM block, as shown in Figure 2–1 and Figure 2–2. The UFM block for the EPM240 device is located on the left side of the device adjacent to the left most LAB column. The UFM block for the EPM570, EPM1270, and EPM2210 devices is located at the bottom left of the device. The UFM input and output signals interface to all types of interconnects (R4 interconnect, C4 interconnect, and DirectLink interconnect to/from adjacent LAB rows). The UFM signals can also be driven from global clocks, GCLK[3..0]. The interface region for the EPM240 device is shown in Figure 2–16. The interface regions for EPM570, EPM1270, and EPM2210 devices are shown in Figure 2–17.

An internal linear voltage regulator provides the necessary 1.8-V internal voltage supply to the device. The voltage regulator supports 3.3-V or 2.5-V supplies on its inputs to supply the 1.8-V internal voltage to the device, as shown in Figure 2–18. The voltage regulator is not guaranteed for voltages that are between the maximum recommended 2.5-V operating voltage and the minimum recommended 3.3-V operating voltage. The MAX IIG and MAX IIZ devices use external 1.8-V supply. The 1.8-V VCC external supply powers the device core directly. Figure 2–18.

Figure 2–19 shows the MAX II IOE structure. Registers from adjacent LABs can drive to or be driven from the IOE’s bidirectional I/O buffers. The Quartus II software automatically attempts to place registers in the adjacent LAB with fast I/O connection to achieve the fastest possible clock-to-output and registered output enable timing. For input registers, the Quartus II software automatically routes the register to guarantee zero hold time. You can set timing assignments in the Quartus II software to achieve desired I/O timing. Fast I/O Connection A dedicated fast I/O connection from the adjacent LAB to the IOEs within an I/O block provides faster output delays for clock-to-output and tPD propagation delays. This connection exists for data output signals, not output enable signals or input signals.

(2) Figure 2–23 is a graphical representation only. Refer to the pin list and the Quartus II software for exact pin locations. Each I/O bank has dedicated VCCIO pins that determine the voltage standard support in that bank. A single device can support 1.5-V, 1.8-V, 2.5-V, and 3.3-V interfaces; each individual bank can support a different standard. Each I/O bank can support multiple standards with the same VCCIO for input and output pins. For example, when VCCIO is 3.3 V, Bank 3 can support LVTTL, LVCMOS, and 3.3-V PCI. VCCIO powers both the input and output buffers in MAX II devices. The JTAG pins for MAX II devices are dedicated pins that cannot be used as regular I/O pins. The pins TMS, TDI, TDO, and TCK support all the I/O standards shown in Table 2–4 on page 2–27 except for PCI. These pins reside in Bank 1 for all MAX II devices and their I/O standard support is controlled by the VCCIO setting for Bank 1. PCI Compliance The MAX II EPM1270 and EPM2210 devices are compliant with PCI applications as well as all 3.3-V electrical specifications in the PCI Local Bus Specification Revision 2.2. These devices are also large enough to support PCI intellectual property (IP) cores. Table 2–5 shows the MAX II device speed grades that meet the PCI timing specifications. MAX II Device Handbook © October 2008 Altera Corporation Chapter 2: MAX II Architecture I/O Structure 2–29 Table 2–5. MAX II Devices and Speed Grades that Support 3.3-V PCI Electrical Specifications and Meet PCI Timing Device EPM1270 EPM2210 33-MHz PCI All Speed Grades All Speed Grades 66-MHz PCI –3 Speed Grade –3 Speed Grade Schmitt Trigger The input buffer for each MAX II device I/O pin has an optional Schmitt trigger setting for the 3.3-V and 2.5-V standards. The Schmitt trigger allows input buffers to respond to slow input edge rates with a fast output edge rate. Most importantly, Schmitt triggers provide hysteresis on the input buffer, preventing slow-rising noisy input signals from ringing or oscillating on the input signal driven into the logic array. This provides system noise tolerance on MAX II inputs, but adds a small, nominal input delay. The JTAG input pins (TMS, TCK, and TDI) have Schmitt trigger buffers that are always enabled. 1 The TCK input is susceptible to high pulse glitches when the input signal fall time is greater than 200 ns for all I/O standards. Output Enable Signals Each MAX II IOE output buffer supports output enable signals for tri-state control. The output enable signal can originate from the GCLK[3..0] global signals or from the MultiTrack interconnect. The MultiTrack interconnect routes output enable signals and allows for a unique output enable for each output or bidirectional pin. MAX II devices also provide a chip-wide output enable pin (DEV_OE) to control the output enable for every output pin in the design. An option set before compilation in the Quartus II software controls this pin. This chip-wide output enable uses its own routing resources and does not use any of the four global resources. If this option is turned on, all outputs on the chip operate normally when DEV_OE is asserted. When the pin is deasserted, all outputs are tri-stated. If this option is turned off, the DEV_OE pin is disabled when the device operates in user mode and is available as a user I/O pin. Programmable Drive Strength The output buffer for each MAX II device I/O pin has two levels of programmable drive strength control for each of the LVTTL and LVCMOS I/O standards. Programmable drive strength provides system noise reduction control for high performance I/O designs. Although a separate slew-rate control feature exists, using the lower drive strength setting provides signal slew-rate control to reduce system noise and signal overshoot without the large delay adder associated with the slew-rate control feature. Table 2–6 shows the possible settings for the I/O standards with drive strength control. The Quartus II software uses the maximum current strength as the default setting. The PCI I/O standard is always set at 20 mA with no alternate setting. © October 2008 Altera Corporation MAX II Device Handbook 2–30 Chapter 2: MAX II Architecture I/O Structure Table 2–6. Programmable Drive Strength (Note 1) I/O Standard 3.3-V LVTTL 3.3-V LVCMOS 2.5-V LVTTL/LVCMOS 1.8-V LVTTL/LVCMOS 1.5-V LVCMOS Note to Table 2–6: (1) The IOH current strength numbers shown are for a condition of a VOUT = VOH minimum, where the VOH minimum is specified by the I/O standard. The IOL current strength numbers shown are for a condition of a VOUT = VOL maximum, where the VOL maximum is specified by the I/O standard. For 2.5-V LVTTL/LVCMOS, the IOH condition is VOUT = 1.7 V and the IOL condition is VOUT = 0.7 V. IOH/IOL Current Strength Setting (mA) 16 8 8 4 14 7 6 3 4 2 Slew-Rate Control The output buffer for each MAX II device I/O pin has a programmable output slewrate control that can be configured for low noise or high-speed performance. A faster slew rate provides high-speed transitions for high-performance systems. However, these fast transitions may introduce noise transients into the system. A slow slew rate reduces system noise, but adds a nominal output delay to rising and falling edges. The lower the voltage standard (for example, 1.8-V LVTTL) the larger the output delay when slow slew is enabled. Each I/O pin has an individual slew-rate control, allowing the designer to specify the slew rate on a pin-by-pin basis. The slew-rate control affects both the rising and falling edges. Open-Drain Output MAX II devices provide an optional open-drain (equivalent to open-collector) output for each I/O pin. This open-drain output enables the device to provide system-level control signals (for example, interrupt and write enable signals) that can be asserted by any of several devices. This output can also provide an additional wired-OR plane. Programmable Ground Pins Each unused I/O pin on MAX II devices can be used as an additional ground pin. This programmable ground feature does not require the use of the associated LEs in the device. In the Quartus II software, unused pins can be set as programmable GND on a global default basis or they can be individually assigned. Unused pins also have the option of being set as tri-stated input pins. MAX II Device Handbook © October 2008 Altera Corporation Chapter 2: MAX II Architecture I/O Structure 2–31 Bus Hold Each MAX II device I/O pin provides an optional bus-hold feature. The bus-hold circuitry can hold the signal on an I/O pin at its last-driven state. Since the bus-hold feature holds the last-driven state of the pin until the next input signal is present, an external pull-up or pull-down resistor is not necessary to hold a signal level when the bus is tri-stated. The bus-hold circuitry also pulls undriven pins away from the input threshold voltage where noise can cause unintended high-frequency switching. The designer can select this feature individually for each I/O pin. The bus-hold output will drive no higher than VCCIO to prevent overdriving signals. If the bus-hold feature is enabled, the device cannot use the programmable pull-up option. The bus-hold circuitry uses a resistor to pull the signal level to the last driven state. The DC and Switching Characteristics chapter in the MAX II Device Handbook gives the specific sustaining current for each VCCIO voltage level driven through this resistor and overdrive current used to identify the next-driven input level. The bus-hold circuitry is only active after the device has fully initialized. The bus-hold circuit captures the value on the pin present at the moment user mode is entered. Programmable Pull-Up Resistor Each MAX II device I/O pin provides an optional programmable pull-up resistor during user mode. If the designer enables this feature for an I/O pin, the pull-up resistor holds the output to the VCCIO level of the output pin’s bank. 1 The programmable pull-up resistor feature should not be used at the same time as the bus-hold feature on a given I/O pin. Programmable Input Delay The MAX II IOE includes a programmable input delay that is activated to ensure zero hold times. A path where a pin directly drives a register, with minimal routing between the two, may require the delay to ensure zero hold time. However, a path where a pin drives a register through long routing or through combinational logic may not require the delay to achieve a zero hold time. The Quartus II software uses this delay to ensure zero hold times when needed. MultiVolt I/O Interface The MAX II architecture supports the MultiVolt I/O interface feature, which allows MAX II devices in all packages to interface with systems of different supply voltages. The devices have one set of VCC pins for internal operation (VCCINT), and up to four sets for input buffers and I/O output driver buffers (VCCIO), depending on the number of I/O banks available in the devices where each set of VCC pins powers one I/O bank. The EPM240 and EPM570 devices have two I/O banks respectively while the EPM1270 and EPM2210 devices have four I/O banks respectively. © October 2008 Altera Corporation MAX II Device Handbook 2–32 Chapter 2: MAX II Architecture Referenced Documents Connect VCCIO pins to either a 1.5-V, 1.8 V, 2.5-V, or 3.3-V power supply, depending on the output requirements. The output levels are compatible with systems of the same voltage as the power supply (that is, when VCCIO pins are connected to a 1.5-V power supply, the output levels are compatible with 1.5-V systems). When VCCIO pins are connected to a 3.3-V power supply, the output high is 3.3 V and is compatible with 3.3-V or 5.0-V systems. Table 2–7 summarizes MAX II MultiVolt I/O support. Table 2–7.

JTAG and In-System Programmability MII51003-1.6 Introduction This chapter discusses how to use the IEEE Standard 1149.1 Boundary-Scan Test (BST) circuitry in MAX II devices and includes the following sections: ■ ■ “IEEE Std. 1149.1 (JTAG) Boundary-Scan Support” on page 3–1 “In System Programmability” on page 3–4 IEEE Std. 1149.1 (JTAG) Boundary-Scan Support All MAX® II devices provide Joint Test Action Group (JTAG) boundary-scan test (BST) circuitry that complies with the IEEE Std. 1149.1-2001 specification. JTAG boundaryscan testing can only be performed at any time after VCCINT and all VCCIO banks have been fully powered and a tCONFIG amount of time has passed. MAX II devices can also use the JTAG port for in-system programming together with either the Quartus® II software or hardware using Programming Object Files (.pof), JamTM Standard Test and Programming Language (STAPL) Files (.jam), or Jam Byte-Code Files (.jbc). The JTAG pins support 1.5-V, 1.8-V, 2.5-V, or 3.3-V I/O standards. The supported voltage level and standard are determined by the VCCIO of the bank where it resides. The dedicated JTAG pins reside in Bank 1 of all MAX II devices. MAX II devices support the JTAG instructions shown in Table 3–1. Table 3–1. MAX II JTAG Instructions (Part 1 of 2) JTAG Instruction SAMPLE/PRELOAD Instruction Code 00 0000 0101 Description Allows a snapshot of signals at the device pins to be captured and examined during normal device operation, and permits an initial data pattern to be output at the device pins. Allows the external circuitry and board-level interconnects to be tested by forcing a test pattern at the output pins and capturing test results at the input pins. Places the 1-bit bypass register between the TDI and TDO pins, which allows the BST data to pass synchronously through selected devices to adjacent devices during normal device operation. Selects the 32-bit USERCODE register and places it between the TDI and TDO pins, allowing the USERCODE to be serially shifted out of TDO. This register defaults to all 1’s if not specified in the Quartus II software. Selects the IDCODE register and places it between TDI and TDO, allowing the IDCODE to be serially shifted out of TDO. Places the 1-bit bypass register between the TDI and TDO pins, which allows the boundary scan test data to pass synchronously through selected devices to adjacent devices during normal device operation, while tri-stating all of the I/O pins.

MAX II JTAG Instructions (Part 2 of 2) JTAG Instruction CLAMP (1) Instruction Code 00 0000 1010 Description Places the 1-bit bypass register between the TDI and TDO pins, which allows the boundary scan test data to pass synchronously through selected devices to adjacent devices during normal device operation, while holding I/O pins to a state defined by the data in the boundary-scan register. This instruction allows you to define the scan chain between TDI and TDO in the MAX II logic array. This instruction is also used for custom logic and JTAG interfaces.

For more information about JTAG BST, refer to the IEEE 1149.1 (JTAG) Boundary-Scan Testing for MAX II Devices chapter in the MAX II Device Handbook. f JTAG Block The MAX II JTAG block feature allows you to access the JTAG TAP and state signals when either the USER0 or USER1 instruction is issued to the JTAG TAP. The USER0 and USER1 instructions bring the JTAG boundary-scan chain (TDI) through the user logic instead of the MAX II device’s boundary-scan cells. Each USER instruction allows for one unique user-defined JTAG chain into the logic array. Parallel Flash Loader The JTAG block ability to interface JTAG to non-JTAG devices is ideal for generalpurpose flash memory devices (such as Intel- or Fujitsu-based devices) that require programming during in-circuit test. The flash memory devices can be used for FPGA configuration or be part of system memory. In many cases, the MAX II device is already connected to these devices as the configuration control logic between the FPGA and the flash device. Unlike ISP-capable CPLD devices, bulk flash devices do not have JTAG TAP pins or connections. For small flash devices, it is common to use the serial JTAG scan chain of a connected device to program the non-JTAG flash device. This is slow and inefficient in most cases and impractical for large parallel flash devices. Using the MAX II device’s JTAG block as a parallel flash loader, with the Quartus II software, to program and verify flash contents provides a fast and costeffective means of in-circuit programming during test. Figure 3–1 shows MAX II being used as a parallel flash loader. © October 2008 Altera Corporation MAX II Device Handbook 3–4 Chapter 3: JTAG and In-System Programmability In System Programmability Figure 3–1.

(2) This function is supported in the Quartus II software. In System Programmability MAX II devices can be programmed in-system via the industry standard 4-pin IEEE Std. 1149.1 (JTAG) interface. In-system programmability (ISP) offers quick, efficient iterations during design development and debugging cycles. The logic, circuitry, and interconnects in the MAX II architecture are configured with flash-based SRAM configuration elements. These SRAM elements require configuration data to be loaded each time the device is powered. The process of loading the SRAM data is called configuration. The on-chip configuration flash memory (CFM) block stores the SRAM element’s configuration data. The CFM block stores the design’s configuration pattern in a reprogrammable flash array. During ISP, the MAX II JTAG and ISP circuitry programs the design pattern into the CFM block’s non-volatile flash array. The MAX II JTAG and ISP controller internally generate the high programming voltages required to program the CFM cells, allowing in-system programming with any of the recommended operating external voltage supplies (that is, 3.3 V/2.5 V or 1.8 V for the MAX IIG and MAX IIZ devices). ISP can be performed anytime after VCCINT and all VCCIO banks have been fully powered and the device has completed the configuration power-up time. By default, during in-system programming, the I/O pins are tri-stated and weakly pulled-up to VCCIO to eliminate board conflicts. The insystem programming clamp and real-time ISP feature allow user control of I/O state or behavior during ISP. For more information, refer to “In-System Programming Clamp” on page 3–6 and “Real-Time ISP” on page 3–7. These devices also offer an ISP_DONE bit that provides safe operation when insystem programming is interrupted. This ISP_DONE bit, which is the last bit programmed, prevents all I/O pins from driving until the bit is programmed. MAX II Device Handbook © October 2008 Altera Corporation Chapter 3: JTAG and In-System Programmability In System Programmability 3–5 IEEE 1532 Support The JTAG circuitry and ISP instruction set in MAX II devices is compliant to the IEEE 1532-2002 programming specification. This provides industry-standard hardware and software for in-system programming among multiple vendor programmable logic devices (PLDs) in a JTAG chain. The MAX II 1532 BSDL files will be released on the Altera website when available. Jam Standard Test and Programming Language (STAPL) The Jam STAPL JEDEC standard, JESD71, can be used to program MAX II devices with in-circuit testers, PCs, or embedded processors. The Jam byte code is also supported for MAX II devices. These software programming protocols provide a compact embedded solution for programming MAX II devices. f For more information, refer to the Using Jam STAPL for ISP via an Embedded Processor chapter in the MAX II Device Handbook. Programming Sequence During in-system programming, 1532 instructions, addresses, and data are shifted into the MAX II device through the TDI input pin. Data is shifted out through the TDO output pin and compared against the expected data. Programming a pattern into the device requires the following six ISP steps. A stand-alone verification of a programmed pattern involves only stages 1, 2, 5, and 6. These steps are automatically executed by third-party programmers, the Quartus II software, or the Jam STAPL and Jam Byte-Code Players. 1. Enter ISP—The enter ISP stage ensures that the I/O pins transition smoothly from user mode to ISP mode. 2. Check ID—Before any program or verify process, the silicon ID is checked. The time required to read this silicon ID is relatively small compared to the overall programming time. 3. Sector Erase—Erasing the device in-system involves shifting in the instruction to erase the device and applying an erase pulse(s). The erase pulse is automatically generated internally by waiting in the run/test/idle state for the specified erase pulse time of 500 ms for the CFM block and 500 ms for each sector of the UFM block. 4. Program—Programming the device in-system involves shifting in the address, data, and program instruction and generating the program pulse to program the flash cells. The program pulse is automatically generated internally by waiting in the run/test/idle state for the specified program pulse time of 75 µs. This process is repeated for each address in the CFM and UFM blocks. 5. Verify—Verifying a MAX II device in-system involves shifting in addresses, applying the verify instruction to generate the read pulse, and shifting out the data for comparison. This process is repeated for each CFM and UFM address. 6. Exit ISP—An exit ISP stage ensures that the I/O pins transition smoothly from ISP mode to user mode. © October 2008 Altera Corporation MAX II Device Handbook 3–6 Chapter 3: JTAG and In-System Programmability In System Programmability Table 3–4 shows the programming times for MAX II devices using in-circuit testers to execute the algorithm vectors in hardware. Software-based programming tools used with download cables are slightly slower because of data processing and transfer limitations. Table 3–4.

This allows updating or reading UFM contents through ISP without altering the current logic array design, or vice versa. By default, these programming files and methods will program the entire flash memory contents, which includes the CFM block and UFM contents. The stand-alone embedded Jam STAPL player and Jam Byte-Code Player provides action commands for programming or reading the entire flash memory (UFM and CFM together) or each independently. f For more information, refer to the Using Jam STAPL for ISP via an Embedded Processor chapter in the MAX II Device Handbook. In-System Programming Clamp By default, the IEEE 1532 instruction used for entering ISP automatically tri-states all I/O pins with weak pull-up resistors for the duration of the ISP sequence. However, some systems may require certain pins on MAX II devices to maintain a specific DC logic level during an in-field update. For these systems, an optional in-system programming clamp instruction exists in MAX II circuitry to control I/O behavior during the ISP sequence. The in-system programming clamp instruction enables the device to sample and sustain the value on an output pin (an input pin would remain tri-stated if sampled) or to explicitly set a logic high, logic low, or tri-state value on any pin. Setting these options is controlled on an individual pin basis using the Quartus II software. f For more information, refer to the Real-Time ISP and ISP Clamp for MAX II Devices chapter in the MAX II Device Handbook. MAX II Device Handbook © October 2008 Altera Corporation Chapter 3: JTAG and In-System Programmability Referenced Documents 3–7 Real-Time ISP For systems that require more than DC logic level control of I/O pins, the real-time ISP feature allows you to update the CFM block with a new design image while the current design continues to operate in the SRAM logic array and I/O pins. A new programming file is updated into the MAX II device without halting the original design’s operation, saving down-time costs for remote or field upgrades. The updated CFM block configures the new design into the SRAM upon the next power cycle. It is also possible to execute an immediate configuration of the SRAM without a power cycle by using a specific sequence of ISP commands. The configuration of SRAM without a power cycle takes a specific amount of time (tCONFIG). During this time, the I/O pins are tri-stated and weakly pulled-up to VCCIO. Design Security All MAX II devices contain a programmable security bit that controls access to the data programmed into the CFM block. When this bit is programmed, design programming information, stored in the CFM block, cannot be copied or retrieved. This feature provides a high level of design security because programmed data within flash memory cells is invisible. The security bit that controls this function, as well as all other programmed data, is reset only when the device is erased. The SRAM is also invisible and cannot be accessed regardless of the security bit setting. The UFM block data is not protected by the security bit and is accessible through JTAG or logic array connections. Programming with External Hardware MAX II devices can be programmed by downloading the information via in-circuit testers, embedded processors, the Altera® ByteblasterMV™, MasterBlaster™, ByteBlaster™ II, and USB-Blaster cables. BP Microsystems, System General, and other programming hardware manufacturers provide programming support for Altera devices. Check their websites for device support information.

Hot Socketing and Power-On Reset in MAX II Devices MII51004-2.1 Introduction MAX® II devices offer hot socketing, also known as hot plug-in or hot swap, and power sequencing support. Designers can insert or remove a MAX II board in a system during operation without undesirable effects to the system bus. The hot socketing feature removes some of the difficulties designers face when using components on printed circuit boards (PCBs) that contain a mixture of 3.3-, 2.5-, 1.8-, and 1.5-V devices. The MAX II device hot socketing feature provides: ■ ■ ■ Board or device insertion and removal Support for any power-up sequence Non-intrusive I/O buffers to system buses during hot insertion This chapter contains the following sections: ■ ■ “MAX II Hot-Socketing Specifications” on page 4–1 “Power-On Reset Circuitry” on page 4–5 MAX II Hot-Socketing Specifications MAX II devices offer all three of the features required for the hot-socketing capability listed above without any external components or special design requirements. The following are hot-socketing specifications: ■ The device can be driven before and during power-up or power-down without any damage to the device itself. I/O pins remain tri-stated during power-up. The device does not drive out before or during power-up, thereby affecting other buses in operation. Signal pins do not drive the VCCIO or VCCINT power supplies. External input signals to device I/O pins do not power the device VCCIO or VCCINT power supplies via internal paths. This is true if the VCCINT and the VCCIO supplies are held at GND. ■ ■ 1 Altera uses GND as reference for the hot-socketing and I/O buffers circuitry designs. You must connect the GND between boards before connecting the VCCINT and the VCCIO power supplies to ensure device reliability and compliance to the hot-socketing specifications. Devices Can Be Driven before Power-Up Signals can be driven into the MAX II device I/O pins and GCLK[3..0] pins before or during power-up or power-down without damaging the device. MAX II devices support any power-up or power-down sequence (VCCIO1, VCCIO2, VCCIO3, VCCIO4, VCCINT), simplifying the system-level design. © October 2008 Altera Corporation MAX II Device Handbook 4–2 Chapter 4: Hot Socketing and Power-On Reset in MAX II Devices Hot Socketing Feature Implementation in MAX II Devices I/O Pins Remain Tri-Stated during Power-Up A device that does not support hot-socketing may interrupt system operation or cause contention by driving out before or during power-up. In a hot socketing situation, the MAX II device’s output buffers are turned off during system power-up. MAX II devices do not drive out until the device attains proper operating conditions and is fully configured. Refer to “Power-On Reset Circuitry” on page 4–5 for information about turn-on voltages. Signal Pins Do Not Drive the VCCIO or VCCINT Power Supplies MAX II devices do not have a current path from I/O pins or GCLK[3..0] pins to the VCCIO or VCCINT pins before or during power-up. A MAX II device may be inserted into (or removed from) a system board that was powered up without damaging or interfering with system-board operation. When hot socketing, MAX II devices may have a minimal effect on the signal integrity of the backplane. AC and DC Specifications You can power up or power down the VCCIO and VCCINT pins in any sequence. During hot socketing, the I/O pin capacitance is less than 8 pF. MAX II devices meet the following hot socketing specifications: ■ ■ The hot socketing DC specification is: | IIOPIN | < 300 μA. The hot socketing AC specification is: | IIOPIN | < 8 mA for 10 ns or less. 1 MAX II devices are immune to latch-up when hot socketing. If the TCK JTAG input pin is driven high during hot socketing, the current on that pin might exceed the specifications above. IIOPIN is the current at any user I/O pin on the device. The AC specification applies when the device is being powered up or powered down. This specification takes into account the pin capacitance but not board trace and external loading capacitance. Additional capacitance for trace, connector, and loading must be taken into consideration separately. The peak current duration due to power-up transients is 10 ns or less. The DC specification applies when all VCC supplies to the device are stable in the powered-up or powered-down conditions. Hot Socketing Feature Implementation in MAX II Devices The hot socketing feature turns off (tri-states) the output buffer during the power-up event (either VCCINT or VCCIO supplies) or power-down event. The hot-socket circuit generates an internal HOTSCKT signal when either VCCINT or VCCIO is below the threshold voltage during power-up or power-down. The HOTSCKT signal cuts off the output buffer to make sure that no DC current (except for weak pull-up leaking) leaks through the pin. When VCC ramps up very slowly during power-up, VCC may still be relatively low even after the power-on reset (POR) signal is released and device configuration is complete.

The weak pull-up resistor (R) from the I/O pin to VCCIO is enabled during download to keep the I/O pins from floating. The 3.3-V tolerance control circuit permits the I/O pins to be driven by 3.3 V before VCCIO and/or VCCINT are powered, and it prevents the I/O pins from driving out when the device is not fully powered or operational. The hot socket circuit prevents I/O pins from internally powering VCCIO and VCCINT when driven by external signals before the device is powered. f For information about 5.0-V tolerance, refer to the Using MAX II Devices in MultiVoltage Systems chapter in the MAX II Device Handbook. Figure 4–2 shows a transistor-level cross section of the MAX II device I/O buffers. This design ensures that the output buffers do not drive when VCCIO is powered before VCCINT or if the I/O pad voltage is higher than VCCIO. This also applies for sudden voltage spikes during hot insertion. The VPAD leakage current charges the 3.3-V tolerant circuit capacitance. © October 2008 Altera Corporation MAX II Device Handbook 4–4 Chapter 4: Hot Socketing and Power-On Reset in MAX II Devices Hot Socketing Feature Implementation in MAX II Devices Figure 4–2.

There are two cases to consider for ESD voltage strikes: positive voltage zap and negative voltage zap. A positive ESD voltage zap occurs when a positive voltage is present on an I/O pin due to an ESD charge event. This can cause the N+ (Drain)/ P-Substrate junction of the N-channel drain to break down and the N+ (Drain)/P-Substrate/N+ (Source) intrinsic bipolar transistor turn on to discharge ESD current from I/O pin to GND. The dashed line (see Figure 4–3) shows the ESD current discharge path during a positive ESD zap. Figure 4–3.

Therefore, the discharge ESD current path is from GND to the I/O pin, as shown in Figure 4–4. Figure 4–4. ESD Protection During Negative Voltage Zap I/O Source PMOS Gate N+ D Drain I/O Drain P-Substrate G NMOS Gate N+ S Source GND GND Power-On Reset Circuitry MAX II devices have POR circuits to monitor VCCINT and VCCIO voltage levels during power-up. The POR circuit monitors these voltages, triggering download from the non-volatile configuration flash memory (CFM) block to the SRAM logic, maintaining tri-state of the I/O pins (with weak pull-up resistors enabled) before and during this process. When the MAX II device enters user mode, the POR circuit releases the I/O pins to user functionality. The POR circuit of the MAX II (except MAX IIZ) device continues to monitor the VCCINT voltage level to detect a brown-out condition. The POR circuit of the MAX IIZ device does not monitor the VCCINT voltage level after the device enters into user mode. More details are provided in the following sub-sections. © October 2008 Altera Corporation MAX II Device Handbook 4–6 Chapter 4: Hot Socketing and Power-On Reset in MAX II Devices Power-On Reset Circuitry Power-Up Characteristics When power is applied to a MAX II device, the POR circuit monitors VCCINT and begins SRAM download at an approximate voltage of 1.7 V or 1.55 V for MAX IIG and MAX IIZ devices. From this voltage reference, SRAM download and entry into user mode takes 200 to 450 µs maximum, depending on device density. This period of time is specified as tCONFIG in the power-up timing section of the DC and Switching Characteristics chapter in the MAX II Device Handbook. Entry into user mode is gated by whether all VCCIO banks are powered with sufficient operating voltage. If VCCINT and VCCIO are powered simultaneously, the device enters user mode within the tCONFIG specifications. If VCCIO is powered more than tCONFIG after VCCINT, the device does not enter user mode until 2 µs after all VCCIO banks are powered. For MAX II and MAX IIG devices, when in user mode, the POR circuitry continues to monitor the VCCINT (but not VCCIO) voltage level to detect a brown-out condition. If there is a VCCINT voltage sag at or below 1.4 V during user mode, the POR circuit resets the SRAM and tri-states the I/O pins. Once VCCINT rises back to approximately 1.7 V (or 1.55 V for MAX IIG devices), the SRAM download restarts and the device begins to operate after tCONFIG time has passed. For MAX IIZ devices, the POR circuitry does not monitor the VCCINT and VCCIO voltage levels after the device enters user mode. If there is a VCCINT voltage sag below 1.4 V during user mode, the functionality of the device will not be guaranteed and you must power down the VCCINT to 0 V for a minimum of 10 µs before powering the VCCINT and VCCIO up again. Once VCCINT rises from 0 V back to approximately 1.55 V, the SRAM download restarts and the device begins to operate after tCONFIG time has passed. Figure 4–5 shows the voltages for POR of MAX II, MAX IIG, and MAX IIZ devices during power-up into user mode and from user mode to power-down or brown-out. 1 All VCCINT and VCCIO pins of all banks must be powered on MAX II devices before entering user mode.

To release clears after tri-states are released, use the DEV_CLRn pin option. To hold the tri-states beyond the power-up configuration time, use the DEV_OE pin option. © October 2008 Altera Corporation MAX II Device Handbook 4–8 Chapter 4: Hot Socketing and Power-On Reset in MAX II Devices Referenced Documents Referenced Documents This chapter refereces the following documents: ■ ■ DC and Switching Characteristics chapter in the MAX II Device Handbook Using MAX II Devices in Multi-Voltage Systems chapter in the MAX II Device Handbook Document Revision History Table 4–1 shows the revision history for this chapter.

MAX II devices have predictable internal delays that enable the designer to determine the worst-case timing of any design. The software provides timing simulation, pointto-point delay prediction, and detailed timing analysis for device-wide performance evaluation.

This section describes and specifies the performance, internal, external, and UFM timing specifications. All specifications are representative of the worst-case supply voltage and junction temperature conditions. Preliminary and Final Timing Timing models can have either preliminary or final status. The Quartus® II software issues an informational message during the design compilation if the timing models are preliminary. Table 5–13 shows the status of the MAX II device timing models. Preliminary status means the timing model is subject to change. Initially, timing numbers are created using simulation results, process data, and other known parameters. These tests are used to make the preliminary numbers as close to the actual timing parameters as possible. Final timing numbers are based on actual device operation and testing. These numbers reflect the actual performance of the device under the worst-case voltage and junction temperature conditions. Table 5–13.
