Pico-ice RP2040 Plus Lattice iCE40UP5K FPGA

Description

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.

Features

• RaspberryPi 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 and Firmware Features

• FPGA clock supplied by the RP2040, easy to program FPGA clock under SW control
• RP2040 can program the FPGA and also provides a pass through UART function
• Examples for communicating to the FPGA over SPI
• Support for ultra low power sleeep mode: can shut down the RP2040 and FPGA while keeping the SRAM powered
