The pico-ice is a small, low cost board with the Raspberry Pi Pico processor (RP2040) and a Lattice Semiconductor iCE40UP5K 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
