RISC-V configurable CPU
Lattice ECP5 (25K, 45K, or 85K LUTs)
64 MB SDRAM
16 MB FLASH
USB 2.0 for Power and Data
Arduino header, GPIOs, etc.
Arduino UNO form factor
Barrel Jack / USB
Linux OS or RTEMS
The Firefly can be powered using the Barrel Jack, USB port, or with a battery (optional). The power source is selected automatically.
The RISC-V has 256 KB of flash program memory (with 4 KB used for the bootloader). The bootloader is factory pre-burnt by Pixilica and is stored in a dedicated ROM memory.
The Firefly runs Debian Linux (or RTEMS or NodeOS) and it can be programmed with a GCC toolchain. The RISC-V IP Core embedded in the Lattice FPGA is fully Customizable (support for both FPU and MMU). The FPGA can be programmed using the Lattice toolchain and any IDE.
