Icepi Zero – A Lattice ECP5 FPGA board in Raspberry Pi Zero form factor (Crowdfunding)

Icepi Zero Lattice LFE5U FPGA board Raspberry Pi Zero form factor

The Icepi Zero is a compact Lattice ECP5 FPGA open-source hardware development board following the Raspberry Pi Zero form factor, and equipped with a microSD card slot, three USB-C ports, a GPDI mini connector for video output, and a 40-pin GPIO header. I was confused at first, since Debashis wrote about the Pico2-ice board a few days ago, but it’s a different design with an RP2350B MCU and a Lattice ICE40U5K FPGA with 5.3K LUTs. Made by Icy Electronics, the Icepi Zero is a pure FPGA board with 24K LUTs, 32MB SRAM, and 16MB QSPI flash that can be used for retro gaming/computer and general FPGA gateware experimentation. Icepi Zero specifications: FPGA – Lattice Semi ECP5U 24k LUTs 112 KiB of RAM 28x 18 x 18 Multipliers Memory – 256 Mbit (32 MB) of 166 MHz SDRAM Storage 128 Mbit (16 MB) of QSPI Flash microSD card slot Video Output […]

Pico2-Ice development board combines Raspberry Pi RP2350B with Lattice iCE40UP5K FPGA

pico2 ice Raspberry Pi RP2350B + iCE40UP5K FPGA development baord

tinyVision.ai has recently released the second-generation ot its open-source hardware pico-ice FPGA development board, upgrading the Raspberry Pi RP2040 to the newer RP2350B along with dedicated user LEDs and buttons for both the MCU and the FPGA. The Pico2-Ice also exposes the RP2350B’s HSTX interface through a 22-pin connector, while keeping the same Lattice iCE40UP5K FPGA. The onboard iCE40UP5K FPGA features 5.3k LUTs, 1 MB SPRAM, and 120 KB DPRAM, along with 4MB SPI flash and 8MB low-power PSRAM. The board also exposes all RP2350 pins and 32 FPGA GPIOs via 2.54mm pitch headers in Pmod format. It includes two RGB LEDs and two pushbuttons (separately mapped to the MCU and the FPGA), and integrates onboard 3.3V/1.2V regulators for power. These features make this board suitable for exploring HDLs, embedded systems, and FPGA programming with open-source tools. Pico2-Ice specifications: Microcontroller – Raspberry Pi RP2350B MCU CPU – Dual-core Arm Cortex-M33 processor @ […]

FPGA-based Commodore 64 Ultimate keyboard PC is compatible with original C64 games

The last original Commodore 64 keyboard computer was sold in 1994, and since then, the Commodore brand and assets have been owned by various companies over the years, until YouTuber Christian Simpson (Perifractic) bought all assets earlier this year to revive the brand and launch the Commodore 64 Ultimate. The Commodore 64 Ultimate is based on an AMD Xilinx Artix-7 FPGA coupled with 128MB RAM and 16MB NOR flash, and can emulate the original computer, giving access to over 10,000 games and programs made for the original C64 computer. The new computer is a mix of old interfaces with analog outputs for CRT TVs, cartridges, SID sockets, and disk drives, and more recent ones, such as HDMI, WiFi, USB, and more. Commodore 64 Ultimate specifications: FPGA – AMD Xilinx Artix-7 FPGA System Memory – 128MB DDR2 RAM Storage 16MB NOR flash Internal microSD card slot Support for USB flash drives […]
