The pico-ice is a small, low cost board with the Raspberry Pi Pico processor ([RP2040](https://www.raspberrypi.com/documentation/microcontrollers/rp2040.html)) and a Lattice Semiconductor [iCE40UP5K](https://www.latticesemi.com/en/Products/FPGAandCPLD/iCE40UltraPlus) FPGA. The board features independent flash for the FPGA and RP2040, low power SSRAM, a couple of pushbuttons and a 3 color LED with _all_ FPGA and RP2040 pins brought out to easy to use 0.1" header pins (arranged as Pmod's) for fast prototyping.

Board Hardware Features:
|
|
|
|
* Raspberry Pi RP2040 processor
|
|
* Lattice UltraPlus ICE40UP5K FPGA with 5.3k LUTs, 1Mb SPRAM, 120Kb DPRAM, 8 Multipliers
|
|
* _ALL_ RP2040 and 32 FPGA GPIO on 0.1” headers
|
|
* 4MB SPI Flash
|
|
* 8MB low power qSPI SRAM
|
|
* RGB LED, shared between the RP2040 and FPGA
|
|
* 2 pushbuttons, 1 dedicated and 1 primarily for processor reset during development but can be repurposed for user applications when not used for reset
|
|
* On board 3.3V and 1.2V Regulators, can supply 3.3V to your project
|
|
* Open source schematic and layout using KiCAD design tools
|
|
* 4 layer board with a solid ground plane for good signal integrity
|
|
|
|
Board Firmware features:
|
|
|
|
* FPGA clock supplied by the RP2040, easy to program FPGA clock under SW control
|
|
* RP2040 can program the FPGA in various ways
|
|
* Examples for communicating to the FPGA from USB to UART or SPI
|
|
* Support for ultra low power sleeep mode: can shut down the RP2040 and FPGA while keeping the SRAM powered
