RISC-V configurable CPU
Lattice ECP5 85K LUTs
2GB DDR3 SDRAM (1GB+ 1GB for Graphics)
32 MB FLASH
Gigabit Ethernet port
USB 3.0 for Power and Data
USB ports for peripherals (e.g. mouse, keyboard)
Arduino header, GPIOs, HDMI, audio, etc.
Arduino UNO form factor
Barrel Jack / USB
Linux OS or RTEMS
The Firefly Pro should be powered using the Barrel Jack. You may also use the USB port or a battery (optional) if your application does not need too much power. 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.
