Fabricated with advanced CMOS technology, the EEPROM–based MAX 3000A devices operate with a 3.3-V supply voltage and provide 600 to 10,000 usable gates, ISP, pin-to-pin delays as fast as 4.5 ns, and counter speeds of up to 227.3 MHz. MAX 3000A devices in the –4, –5, –6, –7, and –10 speed grades are compatible with the timing requirements of the PCI Special Interest Group (PCI SIG) PCI Local Bus Specification, Revision 2.2. See Table 2. 2 Altera Corporation MAX 3000A Programmable Logic Device Family Data Sheet Table 2.

The MAX 3000A architecture easily integrates multiple devices ranging from PALs, GALs, and 22V10s to MACH and pLSI devices. MAX 3000A devices are available in a wide range of packages, including PLCC, PQFP, and TQFP packages. See Table 3. Table 3.

MAX 3000A devices use CMOS EEPROM cells to implement logic functions. The user–configurable MAX 3000A architecture accommodates a variety of independent combinatorial and sequential logic functions. The devices can be reprogrammed for quick and efficient iterations during design development and debugging cycles, and can be programmed and erased up to 100 times. Altera Corporation 3 MAX 3000A Programmable Logic Device Family Data Sheet MAX 3000A devices contain 32 to 512 macrocells, combined into groups of 16 macrocells called logic array blocks (LABs). Each macrocell has a programmable–AND/fixed–OR array and a configurable register with independently programmable clock, clock enable, clear, and preset functions. To build complex logic functions, each macrocell can be supplemented with shareable expander and high–speed parallel expander product terms to provide up to 32 product terms per macrocell. MAX 3000A devices provide programmable speed/power optimization. Speed–critical portions of a design can run at high speed/full power, while the remaining portions run at reduced speed/low power. This speed/power optimization feature enables the designer to configure one or more macrocells to operate at 50% or lower power while adding only a nominal timing delay. MAX 3000A devices also provide an option that reduces the slew rate of the output buffers, minimizing noise transients when non–speed–critical signals are switching. The output drivers of all MAX 3000A devices can be set for 2.5 V or 3.3 V, and all input pins are 2.5–V, 3.3–V, and 5.0-V tolerant, allowing MAX 3000A devices to be used in mixed–voltage systems. MAX 3000A devices are supported by Altera development systems, which are integrated packages that offer schematic, text—including VHDL, Verilog HDL, and the Altera Hardware Description Language (AHDL)—and waveform design entry, compilation and logic synthesis, simulation and timing analysis, and device programming. The software provides EDIF 2 0 0 and 3 0 0, LPM, VHDL, Verilog HDL, and other interfaces for additional design entry and simulation support from other industry–standard PC– and UNIX–workstation–based EDA tools. The software runs on Windows–based PCs, as well as Sun SPARCstation, and HP 9000 Series 700/800 workstations. f Functional Description For more information on development tools, see the MAX+PLUS II Programmable Logic Development System & Software Data Sheet and the Quartus Programmable Logic Development System & Software Data Sheet. The MAX 3000A architecture includes the following elements: ■ ■ ■ ■ ■ Logic array blocks (LABs) Macrocells Expander product terms (shareable and parallel) Programmable interconnect array (PIA) I/O control blocks The MAX 3000A architecture includes four dedicated inputs that can be used as general–purpose inputs or as high–speed, global control signals (clock, clear, and two output enable signals) for each macrocell and I/O pin. Figure 1 shows the architecture of MAX 3000A devices. 4 Altera Corporation MAX 3000A Programmable Logic Device Family Data Sheet Figure 1.

EPM3512A devices have 10 output enables. Logic Array Blocks The MAX 3000A device architecture is based on the linking of high–performance LABs. LABs consist of 16–macrocell arrays, as shown in Figure 1. Multiple LABs are linked together via the PIA, a global bus that is fed by all dedicated input pins, I/O pins, and macrocells. Each LAB is fed by the following signals: ■ ■ 36 signals from the PIA that are used for general logic inputs Global controls that are used for secondary register functions Altera Corporation 5 MAX 3000A Programmable Logic Device Family Data Sheet Macrocells MAX 3000A macrocells can be individually configured for either sequential or combinatorial logic operation. Macrocells consist of three functional blocks: logic array, product–term select matrix, and programmable register. Figure 2 shows a MAX 3000A macrocell. Figure 2. MAX 3000A Macrocell LAB Local Array Global Clear Parallel Logic Expanders (from other macrocells) Global Clocks 2 Programmable Register Register Bypass To I/O Control Block PRN D/T Q ProductTerm Select Matrix VCC Clock/ Enable Select ENA CLRN Clear Select Shared Logic Expanders 36 Signals from PIA 16 Expander Product Terms To PIA Combinatorial logic is implemented in the logic array, which provides five product terms per macrocell. The product–term select matrix allocates these product terms for use as either primary logic inputs (to the OR and XOR gates) to implement combinatorial functions, or as secondary inputs to the macrocell’s register preset, clock, and clock enable control functions. Two kinds of expander product terms (“expanders”) are available to supplement macrocell logic resources: ■ ■ Shareable expanders, which are inverted product terms that are fed back into the logic array Parallel expanders, which are product terms borrowed from adjacent macrocells The Altera development system automatically optimizes product–term allocation according to the logic requirements of the design. 6 Altera Corporation MAX 3000A Programmable Logic Device Family Data Sheet For registered functions, each macrocell flipflop can be individually programmed to implement D, T, JK, or SR operation with programmable clock control. The flipflop can be bypassed for combinatorial operation. During design entry, the designer specifies the desired flipflop type; the Altera development system software then selects the most efficient flipflop operation for each registered function to optimize resource utilization. Each programmable register can be clocked in three different modes: ■ ■ ■ Global clock signal mode, which achieves the fastest clock–to–output performance. Global clock signal enabled by an active–high clock enable. A clock enable is generated by a product term. This mode provides an enable on each flipflop while still achieving the fast clock–to–output performance of the global clock. Array clock implemented with a product term. In this mode, the flipflop can be clocked by signals from buried macrocells or I/O pins. Two global clock signals are available in MAX 3000A devices. As shown in Figure 1, these global clock signals can be the true or the complement of either of the two global clock pins, GCLK1 or GCLK2. Each register also supports asynchronous preset and clear functions. As shown in Figure 2, the product–term select matrix allocates product terms to control these operations. Although the product–term–driven preset and clear from the register are active high, active–low control can be obtained by inverting the signal within the logic array. In addition, each register clear function can be individually driven by the active–low dedicated global clear pin (GCLRn). All registers are cleared upon power-up. By default, all registered outputs drive low when the device is powered up. You can set the registered outputs to drive high upon power-up through the Quartus® II software. Quartus II software uses the NOT Gate Push-Back method, which uses an additional macrocell to set the output high. To set this in the Quartus II software, go to the Assignment Editor and set the Power-Up Level assignment for the register to High. Altera Corporation 7 MAX 3000A Programmable Logic Device Family Data Sheet Expander Product Terms Although most logic functions can be implemented with the five product terms available in each macrocell, highly complex logic functions require additional product terms. Another macrocell can be used to supply the required logic resources. However, the MAX 3000A architecture also offers both shareable and parallel expander product terms (“expanders”) that provide additional product terms directly to any macrocell in the same LAB. These expanders help ensure that logic is synthesized with the fewest possible logic resources to obtain the fastest possible speed. Shareable Expanders Each LAB has 16 shareable expanders that can be viewed as a pool of uncommitted single product terms (one from each macrocell) with inverted outputs that feed back into the logic array. Each shareable expander can be used and shared by any or all macrocells in the LAB to build complex logic functions. Shareable expanders incur a small delay (tSEXP). Figure 3 shows how shareable expanders can feed multiple macrocells. Figure 3. MAX 3000A Shareable Expanders Shareable expanders can be shared by any or all macrocells in an LAB. Macrocell Product-Term Logic Product-Term Select Matrix Macrocell Product-Term Logic 36 Signals from PIA 16 Shared Expanders 8 Altera Corporation MAX 3000A Programmable Logic Device Family Data Sheet Parallel Expanders Parallel expanders are unused product terms that can be allocated to a neighboring macrocell to implement fast, complex logic functions. Parallel expanders allow up to 20 product terms to directly feed the macrocell OR logic, with five product terms provided by the macrocell and 15 parallel expanders provided by neighboring macrocells in the LAB. The Altera development system compiler can automatically allocate up to three sets of up to five parallel expanders to the macrocells that require additional product terms. Each set of five parallel expanders incurs a small, incremental timing delay (tPEXP). For example, if a macrocell requires 14 product terms, the compiler uses the five dedicated product terms within the macrocell and allocates two sets of parallel expanders; the first set includes five product terms, and the second set includes four product terms, increasing the total delay by 2 × tPEXP. Two groups of eight macrocells within each LAB (e.g., macrocells 1 through 8 and 9 through 16) form two chains to lend or borrow parallel expanders. A macrocell borrows parallel expanders from lower– numbered macrocells. For example, macrocell 8 can borrow parallel expanders from macrocell 7, from macrocells 7 and 6, or from macrocells 7, 6, and 5. Within each group of eight, the lowest–numbered macrocell can only lend parallel expanders and the highest–numbered macrocell can only borrow them. Figure 4 shows how parallel expanders can be borrowed from a neighboring macrocell. Altera Corporation 9 MAX 3000A Programmable Logic Device Family Data Sheet Figure 4.

From Previous Macrocell Preset Producter Select Matrix Clock Clear Macrocell ProductTerm Logic Preset ProductTerm Select Matrix Clock Clear Macrocell ProductTerm Logic 36 Signals from PIA 16 Shared Expanders To Next Macrocell Programmable Interconnect Array Logic is routed between LABs on the PIA. This global bus is a programmable path that connects any signal source to any destination on the device. All MAX 3000A dedicated inputs, I/O pins, and macrocell outputs feed the PIA, which makes the signals available throughout the entire device. Only the signals required by each LAB are actually routed from the PIA into the LAB. Figure 5 shows how the PIA signals are routed into the LAB. An EEPROM cell controls one input to a two-input AND gate, which selects a PIA signal to drive into the LAB. 10 Altera Corporation MAX 3000A Programmable Logic Device Family Data Sheet Figure 5. MAX 3000A PIA Routing To LAB PIA Signals While the routing delays of channel–based routing schemes in masked or FPGAs are cumulative, variable, and path–dependent, the MAX 3000A PIA has a predictable delay. The PIA makes a design’s timing performance easy to predict. I/O Control Blocks The I/O control block allows each I/O pin to be individually configured for input, output, or bidirectional operation. All I/O pins have a tri–state buffer that is individually controlled by one of the global output enable signals or directly connected to ground or VCC. Figure 6 shows the I/O control block for MAX 3000A devices. The I/O control block has 6 or 10 global output enable signals that are driven by the true or complement of two output enable signals, a subset of the I/O pins, or a subset of the I/O macrocells.

EPM3512A devices have 10 output enables. When the tri–state buffer control is connected to ground, the output is tri-stated (high impedance), and the I/O pin can be used as a dedicated input. When the tri–state buffer control is connected to VCC, the output is enabled. The MAX 3000A architecture provides dual I/O feedback, in which macrocell and pin feedbacks are independent. When an I/O pin is configured as an input, the associated macrocell can be used for buried logic. 12 Altera Corporation MAX 3000A Programmable Logic Device Family Data Sheet In–System Programmability MAX 3000A devices can be programmed in–system via an industry– standard four–pin IEEE Std. 1149.1-1990 (JTAG) interface. In-system programmability (ISP) offers quick, efficient iterations during design development and debugging cycles. The MAX 3000A architecture internally generates the high programming voltages required to program its EEPROM cells, allowing in–system programming with only a single 3.3–V power supply. During in–system programming, the I/O pins are tri–stated and weakly pulled–up to eliminate board conflicts. The pull–up value is nominally 50 kΩ. MAX 3000A devices have an enhanced ISP algorithm for faster programming. These devices also offer an ISP_Done bit that ensures safe operation when in–system 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. ISP simplifies the manufacturing flow by allowing devices to be mounted on a printed circuit board (PCB) with standard pick–and–place equipment before they are programmed. MAX 3000A devices can be programmed by downloading the information via in–circuit testers, embedded processors, the MasterBlaster communications cable, the ByteBlasterMV parallel port download cable, and the BitBlaster serial download cable. Programming the devices after they are placed on the board eliminates lead damage on high–pin–count packages (e.g., QFP packages) due to device handling. MAX 3000A devices can be reprogrammed after a system has already shipped to the field. For example, product upgrades can be performed in the field via software or modem. The Jam STAPL programming and test language can be used to program MAX 3000A devices with in–circuit testers, PCs, or embedded processors. f For more information on using the Jam STAPL programming and test language, see Application Note 88 (Using the Jam Language for ISP & ICR via an Embedded Processor), Application Note 122 (Using Jam STAPL for ISP & ICR via an Embedded Processor) and AN 111 (Embedded Programming Using the 8051 and Jam Byte-Code). The ISP circuitry in MAX 3000A devices is compliant with the IEEE Std. 1532 specification. The IEEE Std. 1532 is a standard developed to allow concurrent ISP between multiple PLD vendors. Altera Corporation 13 MAX 3000A Programmable Logic Device Family Data Sheet Programming Sequence During in-system programming, instructions, addresses, and data are shifted into the MAX 3000A 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 stages. A stand-alone verification of a programmed pattern involves only stages 1, 2, 5, and 6. 1. Enter ISP. The enter ISP stage ensures that the I/O pins transition smoothly from user mode to ISP mode. The enter ISP stage requires 1 ms. 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. Bulk Erase. Erasing the device in-system involves shifting in the instructions to erase the device and applying one erase pulse of 100 ms. Program. Programming the device in-system involves shifting in the address and data and then applying the programming pulse to program the EEPROM cells. This process is repeated for each EEPROM address. Verify. Verifying an Altera device in-system involves shifting in addresses, applying the read pulse to verify the EEPROM cells, and shifting out the data for comparison. This process is repeated for each EEPROM address. Exit ISP. An exit ISP stage ensures that the I/O pins transition smoothly from ISP mode to user mode. The exit ISP stage requires 1 ms. 2. 3. 4. 5. 6. Programming Times The time required to implement each of the six programming stages can be broken into the following two elements: ■ ■ A pulse time to erase, program, or read the EEPROM cells. A shifting time based on the test clock (TCK) frequency and the number of TCK cycles to shift instructions, address, and data into the device. 14 Altera Corporation MAX 3000A Programmable Logic Device Family Data Sheet By combining the pulse and shift times for each of the programming stages, the program or verify time can be derived as a function of the TCK frequency, the number of devices, and specific target device(s). Because different ISP-capable devices have a different number of EEPROM cells, both the total fixed and total variable times are unique for a single device. Programming a Single MAX 3000A Device The time required to program a single MAX 3000A device in-system can be calculated from the following formula: t PROG =t PPULSE Cycle PTCK + ------------------------------f TCK where: tPROG tPPULSE = Programming time = Sum of the fixed times to erase, program, and verify the EEPROM cells CyclePTCK = Number of TCK cycles to program a device = TCK frequency fTCK The ISP times for a stand-alone verification of a single MAX 3000A device can be calculated from the following formula: Cycle VTCK t VER = t VPULSE + -------------------------------f TCK = Verify time where: tVER = Sum of the fixed times to verify the EEPROM cells tVPULSE CycleVTCK = Number of TCK cycles to verify a device Altera Corporation 15 MAX 3000A Programmable Logic Device Family Data Sheet The programming times described in Tables 4 through 6 are associated with the worst-case method using the enhanced ISP algorithm.

The Altera software can use text– or waveform–format test vectors created with the Altera Text Editor or Waveform Editor to test the programmed device. For added design verification, designers can perform functional testing to compare the functional device behavior with the results of simulation. Data I/O, BP Microsystems, and other programming hardware manufacturers also provide programming support for Altera devices. f IEEE Std. 1149.1 (JTAG) Boundary–Scan Support For more information, see Programming Hardware Manufacturers. MAX 3000A devices include the JTAG BST circuitry defined by IEEE Std. 1149.1–1990. Table 7 describes the JTAG instructions supported by MAX 3000A devices. The pin-out tables found on the Altera web site (http://www.altera.com) or the Altera Digital Library show the location of the JTAG control pins for each device. If the JTAG interface is not required, the JTAG pins are available as user I/O pins. Table 7.

This feature allows total power dissipation to be reduced by 50% or more because most logic applications require only a small fraction of all gates to operate at maximum frequency. The designer can program each individual macrocell in a MAX 3000A device for either high–speed or low–power operation. As a result, speed-critical paths in the design can run at high speed, while the remaining paths can operate at reduced power. Macrocells that run at low power incur a nominal timing delay adder (tLPA) for the tLAD, tLAC, tIC, tACL, tEN, tCPPW and tSEXP parameters. Output Configuration MAX 3000A device outputs can be programmed to meet a variety of system–level requirements. MultiVolt I/O Interface The MAX 3000A device architecture supports the MultiVolt I/O interface feature, which allows MAX 3000A devices to connect to systems with differing supply voltages. MAX 3000A devices in all packages can be set for 2.5–V, 3.3–V, or 5.0–V I/O pin operation. These devices have one set of VCC pins for internal operation and input buffers (VCCINT), and another set for I/O output drivers (VCCIO). The VCCIO pins can be connected to either a 3.3–V or 2.5–V power supply, depending on the output requirements. When the VCCIO pins are connected to a 2.5–V power supply, the output levels are compatible with 2.5–V systems. When the VCCIO pins are connected to a 3.3–V power supply, the output high is at 3.3 V and is therefore compatible with 3.3-V or 5.0–V systems. Devices operating with VCCIO levels lower than 3.0 V incur a nominally greater timing delay of tOD2 instead of tOD1. Inputs can always be driven by 2.5–V, 3.3–V, or 5.0–V signals. Table 11 summarizes the MAX 3000A MultiVolt I/O support. Table 11. MAX 3000A MultiVolt I/O Support VCCIO Voltage 2.5 2.5 3.3 Note: (1) When VCCIO is 3.3 V, a MAX 3000A device can drive a 2.5–V device that has 3.3–V tolerant inputs.

This open–drain output enables the device to provide system–level control signals (e.g., interrupt and write enable signals) that can be asserted by any of several devices. It can also provide an additional wired–OR plane. Open-drain output pins on MAX 3000A devices (with a pull-up resistor to the 5.0-V supply) can drive 5.0-V CMOS input pins that require a high VIH. When the open-drain pin is active, it will drive low. When the pin is inactive, the resistor will pull up the trace to 5.0 V, thereby meeting CMOS requirements. The open-drain pin will only drive low or tri-state; it will never drive high. The rise time is dependent on the value of the pull-up resistor and load impedance. The IOL current specification should be considered when selecting a pull-up resistor Slew–Rate Control The output buffer for each MAX 3000A I/O pin has an adjustable output slew rate 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 delay of 4 to 5 ns. When the configuration cell is turned off, the slew rate is set for low–noise performance. Each I/O pin has an individual EEPROM bit that controls the slew rate, allowing designers to specify the slew rate on a pin–by–pin basis. The slew rate control affects both the rising and falling edges of the output signal. Design Security All MAX 3000A devices contain a programmable security bit that controls access to the data programmed into the device. When this bit is programmed, a design implemented in the device cannot be copied or retrieved. This feature provides a high level of design security because programmed data within EEPROM cells is invisible. The security bit that controls this function, as well as all other programmed data, is reset only when the device is reprogrammed. MAX 3000A devices are fully tested. Complete testing of each programmable EEPROM bit and all internal logic elements ensures 100% programming yield. AC test measurements are taken under conditions equivalent to those shown in Figure 8. Test patterns can be used and then erased during early stages of the production flow. Generic Testing Altera Corporation 21 MAX 3000A Programmable Logic Device Family Data Sheet Figure 8. MAX 3000A AC Test Conditions Power supply transients can affect AC measurements. Simultaneous transitions of multiple outputs should be avoided for accurate measurement. Threshold tests must not be performed under AC conditions. Large–amplitude, fast– ground–current transients normally occur as the device outputs discharge the load capacitances. When these transients flow through the parasitic inductance between the device ground pin and the test system ground, significant reductions in observable noise immunity can result. Numbers in brackets are for 2.5–V outputs. Numbers without brackets are for 3.3–V devices or outputs.

(3) All pins, including dedicated inputs, I/O pins, and JTAG pins, may be driven before VCCINT and VCCIO are powered. (4) These values are specified under the recommended operating conditions, as shown in Table 13 on page 23. (5) The parameter is measured with 50% of the outputs each sourcing the specified current. The IOH parameter refers to high–level TTL or CMOS output current. (6) The parameter is measured with 50% of the outputs each sinking the specified current. The IOL parameter refers to low–level TTL, PCI, or CMOS output current. (7) This value is specified during normal device operation. During power-up, the maximum leakage current is ±300 μA. (8) This pull–up exists while devices are programmed in–system and in unprogrammed devices during power–up. (9) Capacitance is measured at 25° C and is sample–tested only. The OE1 pin (high–voltage pin during programming) has a maximum capacitance of 20 pF. (10) The POR time for all MAX 3000A devices does not exceed 100 μs. The sufficient VCCINT voltage level for POR is 3.0 V. The device is fully initialized within the POR time after VCCINT reaches the sufficient POR voltage level.

The VCCIO and VCCINT power planes can be powered in any order. Signals can be driven into MAX 3000A devices before and during power-up without damaging the device. In addition, MAX 3000A devices do not drive out during power-up. Once operating conditions are reached, MAX 3000A devices operate as specified by the user. Altera Corporation 25 MAX 3000A Programmable Logic Device Family Data Sheet Timing Model MAX 3000A device timing can be analyzed with the Altera software, with a variety of popular industry–standard EDA simulators and timing analyzers, or with the timing model shown in Figure 10. MAX 3000A devices have predictable internal delays that enable the designer to determine the worst–case timing of any design. The software provides timing simulation, point–to–point delay prediction, and detailed timing analysis for device–wide performance evaluation. Figure 10.

See Figure 11 on page 27 for more information on switching waveforms. These values are specified for a PIA fan–out of one LAB (16 macrocells). For each additional LAB fan–out in these devices, add an additional 0.1 ns to the PIA timing value. This minimum pulse width for preset and clear applies for both global clear and array controls. The tLPA parameter must be added to this minimum width if the clear or reset signal incorporates the tLAD parameter into the signal path. These parameters are measured with a 16–bit loadable, enabled, up/down counter programmed into each LAB. The tLPA parameter must be added to the tLAD, tLAC, tIC, tEN, tSEXP, tACL, and tCPPW parameters for macrocells running in low–power mode. (4) (5) 38 Altera Corporation MAX 3000A Programmable Logic Device Family Data Sheet Power Consumption Supply power (P) versus frequency (fMAX, in MHz) for MAX 3000A devices is calculated with the following equation: P = PINT + PIO = ICCINT × VCC + PIO The PIO value, which depends on the device output load characteristics and switching frequency, can be calculated using the guidelines given in Application Note 74 (Evaluating Power for Altera Devices). The ICCINT value depends on the switching frequency and the application logic. The ICCINT value is calculated with the following equation: ICCINT = (A × MCTON) + [B × (MCDEV – MCTON)] + (C × MCUSED × fMAX × togLC) The parameters in the ICCINT equation are: MCTON MCDEV MCUSED fMAX togLC A, B, C = Number of macrocells with the Turbo BitTM option turned on, as reported in the Quartus II or MAX+PLUS II Report File (.rpt) = Number of macrocells in the device = Total number of macrocells in the design, as reported in the RPT File = Highest clock frequency to the device = Average percentage of logic cells toggling at each clock (typically 12.5%) = Constants (shown in Table 26) Table 26.

Actual ICC should be verified during operation because this measurement is sensitive to the actual pattern in the device and the environmental operating conditions.
