iCE40 Ultra™ Family Data Sheet DS1048 Version 2.0, June 2016 iCE40 Ultra Family Data Sheet Introduction June 2016 Data Sheet DS1048 General Description iCE40 Ultra family is an ultra-low power FPGA and sensor manager designed for ultra-low power mobile applications, such as smartphones, tablets and hand-held devices. The iCE40 Ultra family includes integrated SPI and I2C blocks to interface with virtually all mobile sensors and application processors. The iCE40 Ultra family also features two on-chip oscillators, 10 kHz and 48 MHz. The LFOSC (10 kHz) is ideal for low power function in always-on applications, while HFOSC (48 MHz) can be used for awaken activities. The iCE40 Ultra family also features DSP functional block to off-load Application Processor to pre-process information sent from the mobile sensors. The embedded RGB PWM IP, with the three 24 mA constant current RGB outputs on the iCE40 Ultra provides all the necessary logic to directly drive the service LED, without the need of external MOSFET or buffer. The 500 mA constant current IR driver output provides a direct interface to external LED for application such as IrDA functions. Users simply implement the modulation logic that meets his needs, and connect the IR driver directly to the LED, without the need of external MOSFET or buffer. This high current IR driver can also be used as Barcode Emulation, sending barcode information to external Barcode Reader. The iCE40 Ultra family of devices are targeting for mobile applications to perform functions such as IrDA, Service LED, Barcode Emulation, GPIO Expander, SDIO Level Shift, and other custom functions. The iCE40 Ultra family features three device densities, from 1100 to 3520 Look Up Tables (LUTs) of logic with programmable I/Os that can be used as either SPI/I2C interface ports or general purpose I/O’s. It also has up to 80 kbits of Block RAMs to work with user logic.

In addition to LUT-based, low-cost programmable logic, these devices also feature Embedded Block RAM (EBR), on-chip Oscillators (LFOSC, HFOSC), two hardened I2C Controllers, two hardened SPI Controllers, three 24 mA RGB LED open-drain drivers, a 500 mA IR LED open-drain drivers, and DSP blocks. These features allow the devices to be used in low-cost, high-volume consumer and mobile applications. The iCE40 Ultra FPGAs are available in very small form factor packages, as small as 2.078 mm x 2.078 mm. The small form factor allows the device to easily fit into a lot of mobile applications, where space can be limited. Table 1-1 shows the LUT densities, package and I/O pin count. The iCE40 Ultra devices offer I/O features such as pull-up resistors. Pull-up features are controllable on a “per-pin” basis. The iCE40 Ultra devices also provide flexible, reliable and secure configuration from on-chip NVCM. These devices can also configure themselves from external SPI Flash, or be configured by an external master such as a CPU. Lattice provides a variety of design tools that allow complex designs to be efficiently implemented using the iCE40 Ultra family of devices. Popular logic synthesis tools provide synthesis library support for iCE40 Ultra. Lattice design tools use the synthesis tool output along with the user-specified preferences and constraints to place and route the design in the iCE40 Ultra device. These tools extract the timing from the routing and back-annotate it into the design for timing verification. Lattice provides in the iCE40 Ultra 1K and 2K device the embedded RGB PWM IP at no extra cost of LUT available to the user, to perform controlling the RGB LED function. This embedded IP allow users to control color, LED ON/ OFF time, and breathe rate of the LED. For more information, please refer to Usage Guide in Lattice Design Software. Lattice provides many pre-engineered IP (Intellectual Property) modules, including a number of reference designs, licensed free of charge, optimized for the iCE40 Ultra FPGA family. Lattice also can provide fully verified bitstream for some of the widely used target functions in mobile device applications, such as ultra-low power sensor management, gesture recognition, IR remote, barcode emulator functions. Users can use these functions as offered by Lattice, or they can use the design to create their own unique required functions. For more information regarding Lattice's reference designs or fully-verified bitstreams, please contact your local Lattice representative. 1-2 iCE40 Ultra Family Data Sheet Architecture June 2016 Data Sheet DS1048 Architecture Overview The iCE40 Ultra family architecture contains an array of Programmable Logic Blocks (PLB), two Oscillator Generators, two user configurable I2C controllers, two user configurable SPI controllers, and blocks of sysMEM™ Embedded Block RAM (EBR) surrounded by Programmable I/O (PIO). Figure 2-1shows the block diagram of the iCE5LP4K device. Figure 2-1. iCE5LP-4K Device, Top View I2C NVCM 5 4 Kbit RAM 5 4 Kbit RAM DSP 5 4 Kbit RAM LFOSC 5 4 Kbit RAM DSP DSP HFOSC IR Drv 8 Logic Cells = Programmable Logic Block I/O Bank 0 DSP RGB Drv PLB I2C config SPI I/O Bank 2 I/O Bank 1 SPI Carry Logic 4-Input Look-up Table (LUT) Flip-flop with Enable and Reset Controls The Programmable Logic Blocks (PLB) and sysMEM EBR blocks, are arranged in a two-dimensional grid with rows and columns. Each column has either PLB or EBR blocks. The PIO cells are located at the top and bottom of the device, arranged in banks. The PLB contains the building blocks for logic, arithmetic, and register functions. The PIOs utilize a flexible I/O buffer referred to as a sysIO buffer that supports operation with a variety of interface standards. The blocks are connected with many vertical and horizontal routing channel resources. The place and route software tool automatically allocates these routing resources. In the iCE40 Ultra family, there are three sysIO banks, one on top and two at the bottom. User can connect some VCCIOs together, if all the I/Os are using the same voltage standard. Refer to the details in later sections of this document on Power Up Sequence. The sysMEM EBRs are large 4 kbit, dedicated fast memory blocks. These blocks can be configured as RAM, ROM or FIFO with user logic using PLBs. Every device in the family has two user SPI ports, one of these (right side) SPI port also supports programming and configuration of the device. The iCE40 Ultra also includes two user I2C ports, two Oscillators, and high current RGB and IR LED sinks. © 2016 Lattice Semiconductor Corp.

Each PLB consists of eight interconnected Logic Cells (LC) as shown in Figure 2-2. Each LC contains one LUT and one register. Figure 2-2. PLB Block Diagram Shared Block-Level Controls Clock Programmable Logic Block (PLB) Enable FCOUT 1 Set/Reset 0 Logic Cell Carry Logic DFF 8 Logic Cells (LCs) I0 D O Q EN I1 LUT I2 SR I3 FCIN Four-input Look-Up Table (LUT) Flip-flop with optional enable and set or reset controls = Statically defined by configuration program Logic Cells Each Logic Cell includes three primary logic elements shown in Figure 2-2. • A four-input Look-Up Table (LUT) builds any combinational logic function, of any complexity, requiring up to four inputs. Similarly, the LUT element behaves as a 16x1 Read-Only Memory (ROM). Combine and cascade multiple LUTs to create wider logic functions. • A ‘D’-style Flip-Flop (DFF), with an optional clock-enable and reset control input, builds sequential logic functions. Each DFF also connects to a global reset signal that is automatically asserted immediately following device configuration. • Carry Logic boosts the logic efficiency and performance of arithmetic functions, including adders, subtracters, comparators, binary counters and some wide, cascaded logic functions. Table 2-1.

If Set/Reset is not used, then the flip-flop is never set/reset, except when cleared immediately after configuration. 2-2 Architecture iCE40 Ultra Family Data Sheet Routing There are many resources provided in the iCE40 Ultra devices to route signals individually with related control signals. The routing resources consist of switching circuitry, buffers and metal interconnect (routing) segments. The inter-PLB connections are made with three different types of routing resources: Adjacent (spans two PLBs), x4 (spans five PLBs) and x12 (spans thirteen PLBs). The Adjacent, x4 and x12 connections provide fast and efficient connections in the diagonal, horizontal and vertical directions. The design tool takes the output of the synthesis tool and places and routes the design. Clock/Control Distribution Network Each iCE40 Ultra device has six global inputs, two pins on the top bank and four pins on the bottom bank These global inputs can be used as high fanout nets, clock, reset or enable signals. The dedicated global pins are identified as Gxx and each drives one of the eight global buffers. The global buffers are identified as GBUF[7:0]. These six inputs may be used as general purpose I/O if they are not used to drive the clock nets. Table 2-2 lists the connections between a specific global buffer and the inputs on a PLB. All global buffers optionally connect to the PLB CLK input. Any four of the eight global buffers can drive logic inputs to a PLB. Even-numbered global buffers optionally drive the Set/Reset input to a PLB. Similarly, odd-numbered buffers optionally drive the PLB clock-enable input. GBUF[7:6, 3:0] can connect directly to G[7:6, 3:0] pins respectively. GBUF4 and GBUF5 can connect to the two on-chip Oscillator Generators (GBUF4 connects to LFOSC, GBUF5 connects to HFOSC). Table 2-2. Global Buffer (GBUF) Connections to Programmable Logic Blocks Global Buffer Clock Clock Enable GBUF0   GBUF1  GBUF2  GBUF3  GBUF4 LUT Inputs Yes, any 4 of 8 GBUF Inputs  GBUF5  GBUF6  GBUF7  Reset        The maximum frequency for the global buffers are shown in the iCE40 Ultra External Switching Characteristics tables later in this document. Global Hi-Z Control The global high-impedance control signal, GHIZ, connects to all I/O pins on the iCE40 Ultra device. This GHIZ signal is automatically asserted throughout the configuration process, forcing all user I/O pins into their high-impedance state. Global Reset Control The global reset control signal connects to all PLB and PIO flip-flops on the iCE40 Ultra device. The global reset signal is automatically asserted throughout the configuration process, forcing all flip-flops to their defined wake-up state. For PLB flip-flops, the wake-up state is always reset, regardless of the PLB flip-flop primitive used in the application. 2-3 Architecture iCE40 Ultra Family Data Sheet sysCLOCK Phase Locked Loops (PLLs) The sysCLOCK PLLs provide the ability to synthesize clock frequencies. The iCE40 Ultra devices have one sysCLOCK PLL. REFERENCECLK is the reference frequency input to the PLL and its source can come from an external I/O pin, the internal Oscillator Generators from internal routing. EXTFEEDBACK is the feedback signal to the PLL which can come from internal routing or an external I/O pin. The feedback divider is used to multiply the reference frequency and thus synthesize a higher frequency clock output. The PLLOUT output has an output divider, thus allowing the PLL to generate different frequencies for each output. The output divider can have a value from 1 to 64 (in increments of 2X). The PLLOUT outputs can all be used to drive the iCE40 Ultra global clock network directly or general purpose routing resources can be used. The LOCK signal is asserted when the PLL determines it has achieved lock and de-asserted if a loss of lock is detected. A block diagram of the PLL is shown in Figure 2-3. The timing of the device registers can be optimized by programming a phase shift into the PLLOUT output clock which will advance or delay the output clock with reference to the REFERENCECLK clock. This phase shift can be either programmed during configuration or can be adjusted dynamically. In dynamic mode, the PLL may lose lock after a phase adjustment on the output used as the feedback source and not relock until the tLOCK parameter has been satisfied. There is an additional feature in the iCE40 Ultra PLL. There are 2 FPGA controlled inputs, SCLK and SDI, that allows the user logic to serially shift in data thru SDI, clocked by SCLK clock. The data shifted in would change the configuration settings of the PLL. This feature allows the PLL to be time multiplexed for different functions, with different clock rates. After the data is shifted in, user would simply pulse the RESET input of the PLL block, and the PLL will re-lock with the new settings. For more details, please refer to TN1251, iCE40 sysCLOCK PLL Design and Usage Guide. Figure 2-3.

This memory can be used for a wide variety of purposes including data buffering, and FIFO. sysMEM Memory Block The sysMEM block can implement single port, pseudo dual port, or FIFO memories with programmable logic resources. Each block can be used in a variety of depths and widths as shown in Table 2-4. 2-5 Architecture iCE40 Ultra Family Data Sheet Table 2-4. sysMEM Block Configurations1 Block RAM Configuration and Size WADDR Port Size (Bits) WDATA Port Size (Bits) RADDR Port Size (Bits) RDATA Port Size (Bits) MASK Port Size (Bits) SB_RAM256x16 SB_RAM256x16NR SB_RAM256x16NW SB_RAM256x16NRNW 256x16 (4 k) 8 [7:0] 16 [15:0] 8 [7:0] 16 [15:0] 16 [15:0] SB_RAM512x8 SB_RAM512x8NR SB_RAM512x8NW SB_RAM512x8NRNW 512x8 (4 k) 9 [8:0] 8 [7:0] 9 [8:0] 8 [7:0] No Mask Port SB_RAM1024x4 SB_RAM1024x4NR SB_RAM1024x4NW SB_RAM1024x4NRNW 1024x4 (4 k) 10 [9:0] 4 [3:0] 10 [9:0] 4 [3:0] No Mask Port SB_RAM2048x2 SB_RAM2048x2NR SB_RAM2048x2NW SB_RAM2048x2NRNW 2048x2 (4 k) 11 [10:0] 2 [1:0] 11 [10:0] 2 [1:0] No Mask Port Block RAM Configuration 1.

The configuration SPI interface signals are powered by SPI_VCCIO1. Please refer to the Pin Information Summary table. Programmable I/O (PIO) The programmable logic associated with an I/O is called a PIO. The individual PIOs are connected to their respective sysIO buffers and pads. The PIOs are placed on the top and bottom of the devices. Figure 2-8.

To save power, the optional iCEGateTM latch can selectively freeze the state of individual, non-registered inputs within an I/O bank. Note that the freeze signal is common to the bank. These blocks can operate in a variety of modes along with the necessary clock and selection logic. Input Register Block The input register blocks for the PIOs on all edges contain registers that can be used to condition high-speed interface signals before they are passed to the device core. Output Register Block The output register block can optionally register signals from the core of the device before they are passed to the sysIO buffers. Figure 2-9 shows the input/output register block for the PIOs. 2-13 Architecture iCE40 Ultra Family Data Sheet Figure 2-9. iCE I/O Register Block Diagram PIO Pair CLOCK_ENABLE OUTPUT_CLK INPUT_CLK (1,0) LATCH_INPUT_VALUE D_IN_1 D_IN_0 Pad D_OUT_1 D_OUT_0 (1,0) 0 1 OUTPUT_ENABLE (1,0) LATCH_INPUT_VALUE D_IN_1 D_IN_0 Pad D_OUT_1 D_OUT_0 (1,0) 0 1 OUTPUT_ENABLE = Statically defined by configuration program.

These buffers are arranged around the periphery of the device in groups referred to as banks. The sysIO buffers allow users to implement a wide variety of standards that are found in today’s systems with LVCMOS interfaces. 2-14 Architecture iCE40 Ultra Family Data Sheet Typical I/O Behavior During Power-up The internal power-on-reset (POR) signal is deactivated when VCC, SPI_VCCIO1, and VPP_2V5 reach the level defined in the Power-On-Reset Voltage table in the DC and Switching Characteristics section of this data sheet. After the POR signal is deactivated, the FPGA core logic becomes active. You must ensure that all VCCIO banks are active with valid input logic levels to properly control the output logic states of all the I/O banks that are critical to the application. The default configuration of the I/O pins in a device prior to configuration is tri-stated with a weak pull-up to VCCIO. The I/O pins maintain the pre-configuration state until VCC, SPI_VCCIO1, and VPP_2V5 reach the defined levels. The I/Os take on the software user-configured settings only after POR signal is deactivated and the device performs a proper download/configuration. Unused I/Os are automatically blocked and the pull-up termination is disabled. Supported Standards The iCE40 Ultra sysIO buffer supports both single-ended input/output standards, and used as differential comparators. The buffer supports the LVCMOS 1.8, 2.5, and 3.3 V standards. The buffer has individually configurable options for bus maintenance (weak pull-up or none). Table 2-8 and Table 2-9 show the I/O standards (together with their supply and reference voltages) supported by the iCE40 Ultra devices. Differential Comparators The iCE40 Ultra devices provide differential comparator on pairs of I/O pins. These comparators are useful in some mobile applications. Please refer to the Pin Information Summary section to locate the corresponding paired I/Os with differential comparators. Table 2-8.

One is tailored for low-power operation that runs at low frequency (LFOSC). Both Oscillators are controlled with internally generated current. The LFOSC runs at nominal frequency of 10 kHz. The high frequency oscillator (HFOSC) runs at a nominal frequency of 48 MHz, divisible to 24 MHz, 12 MHz, or 6 MHz by user option. The LFOSC can be used to perform all always-on functions, with the lowest power possible. The HFOSC can be enabled when the always-on functions detect a condition that would need to wake up the system to perform higher frequency functions. 2-15 Architecture iCE40 Ultra Family Data Sheet User I2C IP The iCE40 Ultra devices have two I2C IP cores. Either of the two cores can be configured either as an I2C master or as an I2C slave. The pins for the I2C interface are not pre-assigned. User can use any General Purpose I/O pins. In each of the two cores, there are options to delay the either the input or the output, or both, by 50 ns nominal, using dedicated on-chip delay elements. This provides an easier interface with any external I2C components. When the IP core is configured as master, it will be able to control other devices on the I2C bus through the preassigned pin interface. When the core is configured as the slave, the device will be able to provide I/O expansion to an I2C Master. The I2C cores support the following functionality: • Master and Slave operation • 7-bit and 10-bit addressing • Multi-master arbitration support • Clock stretching • Up to 400 kHz data transfer speed • General Call support • Optionally delaying input or output data, or both For further information on the User I2C, please refer to TN1274, iCE40 SPI/I2C Hardened IP Usage Guide. User SPI IP The iCE40 Ultra devices have two SPI IP cores. The pins for the SPI interface are not pre-assigned. User can use any General Purpose I/O pins. Both SPI IP cores can be configured as a SPI master or as a slave. When the SPI IP core is configured as a master, it controls the other SPI enabled devices connected to the SPI Bus. When SPI IP core is configured as a slave, the device will be able to interface to an external SPI master. The SPI IP core supports the following functions: • Configurable Master and Slave modes • Full-Duplex data transfer • Mode fault error flag with CPU interrupt capability • Double-buffered data register • Serial clock with programmable polarity and phase • LSB First or MSB First Data Transfer For further information on the User SPI, please refer to TN1274, iCE40 SPI/I2C Hardened IP Usage Guide. High Current LED Drive I/O Pins The iCE40 Ultra family devices offer multiple high current LED drive outputs in each device in the family to allow the iCE40 Ultra product to drive LED signals directly on mobile applications. There are three outputs on each device that can sink up to 24 mA current. These outputs are open-drain outputs, and provides sinking current to an LED connecting to the positive supply. These three outputs are designed to drive the RBG LEDs, such as the service LED found in a lot of mobile devices. An embedded RGB PWM IP is also offered in the family. This RGB drive current is user programmable from 4 mA to 24 mA, in increments of 4 mA. This output functions as General Purpose I/O with open-drain when the high current LED drive is not needed. 2-16 Architecture iCE40 Ultra Family Data Sheet There is one output on each device that can sink up to 500 mA current. This output is open-drain, and provides sinking current to drive an external IR LED connecting to the positive supply. This IR drive current is user programmable from 50 mA to 500 mA in increments of 50 mA. This output functions as General Purpose I/O with opendrain when the high current LED drive is not needed. Embedded PWM IP To provide an easier usage of the RGB high current drivers to drive RGB LED, a Pulse-Width Modulator IP can be embedded into the user design. This PWM IP provides the flexibility for user to dynamically change the settings on the ON-time duration, OFF-time duration, and ability to turn the LED lights on and off gradually with user set breath-on and breath-off time. For additional information on the embedded PWM IP, please refer to TN1288, iCE40 LED Driver Usage Guide. Non-Volatile Configuration Memory All iCE40 Ultra devices provide a Non-Volatile Configuration Memory (NVCM) block which can be used to configure the device. For more information on the NVCM, please refer to TN1248, iCE40 Programming and Configuration. iCE40 Ultra Programming and Configuration This section describes the programming and configuration of the iCE40 Ultra family. Device Programming The NVCM memory can be programmed through the SPI port. The SPI port is located in Bank 1, using SPI_VCCIO1 power supply. Device Configuration There are various ways to configure the Configuration RAM (CRAM), using SPI port, including: • From a SPI Flash (Master SPI mode) • System microprocessor to drive a Serial Slave SPI port (SSPI mode) For more details on configuring the iCE40 Ultra, please see TN1248, iCE40 Programming and Configuration. Power Saving Options The iCE40 Ultra devices feature iCEGate and PLL low power mode to allow users to meet the static and dynamic power requirements of their applications. Table 2-10 describes the function of these features. Table 2-10. iCE40 Ultra Power Saving Features Description Device Subsystem Feature Description PLL When LATCHINPUTVALUE is enabled, puts the PLL into low-power mode; PLL output held static at last input clock value. iCEGate To save power, the optional iCEGate latch can selectively freeze the state of individual, non-registered inputs within an I/O bank. Registered inputs are effectively frozen by their associated clock or clock-enable control. 2-17 iCE40 Ultra Family Data Sheet DC and Switching Characteristics June 2016 Data Sheet DS1048 Absolute Maximum Ratings1, 2, 3 Supply Voltage VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 1.42 V Output Supply Voltage VCCIO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 3.60 V NVCM Supply Voltage VPP_2V5 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 3.60 V PLL Supply Voltage VCCPLL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 1.42 V I/O Tri-state Voltage Applied. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 3.60 V Dedicated Input Voltage Applied . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 3.60 V Storage Temperature (Ambient). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –65 °C to 150 °C Junction Temperature (TJ) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –65 °C to 125 °C 1.

Only three supply rails are monitored by the POR circuitry as follows: (1) VCC, (2) SPI_VCCIO1 and (3) VPP_2V5. All other supply pins have no effect on the power-on reset feature of the device. Note that all supply voltage pins must be connected to power supplies for normal operation (including device configuration). Power-Up Supply Sequencing It is recommended to bring up the power supplies in the following order. Note that there is no specified timing delay between the power supplies, however, there is a requirement for each supply to reach a level of 0.5V, or higher, before any subsequent power supplies in the sequence are applied. 1. VCC and VCCPLL should be the first two supplies to be applied. Note that these two supplies can be tied together subject to the recommendation to include a RC-based noise filter on the VCCPLL (Please refer to TN1252, iCE40 Hardware Checklist.) 2. SPI_VCCIO1 should be the next supply, and can be applied any time after the previous supplies (VCC and VCCPLL) have reached as level of 0.5 V or higher. 3. VPP_2V5 should be the next supply, and can be applied any time after previous supplies (VCC, VCCPLL and SPI_VCCIO1) have reached a level of 0.5 V or higher. 4. Other Supplies (VCCIO0 and VCCIO2) do not affect device power-up functionality, and they can be applied any time after the initial power supplies (VCC and VCCPLL) have reached a level of 0.5 V or greater. There is no power down sequence required. However, when partial power supplies are powered down, it is required the above sequence to be followed when these supplies are repowered up again. External Reset When all power supplies have reached to their minimum operating voltage defined in Minimum Operation Condition Table, it is required to either keep CRESET_B LOW, or toggle CRESET_B from HIGH to LOW, for a duration of tCRESET_B, and release it to go HIGH, to start configuration download from either the internal NVCM or the external Flash memory. Figure 3-1 shows Power-Up sequence when SPI_VCCIO1 and VPP_2V5 are connected separately, and the CRESET_B signal triggers configuration download. Figure 3-2 shows when SPI_VCCIO1 and VPP_2V5 connected together. All power supplies should be powered up during configuration. Before and during configuration, the I/Os are held in tri-state. I/Os are released to user functionality once the device has finished configuration. Figure 3-1.
