Hummingbird FPGA Development Board

Hummingbird FPGA Development Board which is to prototype the Nuclei evaluation SoC (included RISC-V Core) in the FPGA,with the following characteristics:

  • Xilinx FPGA Chip (XC7A75T-2FGG484I).
  • Two DDR Chips (MT41K128M16JT-125K DDR III).
  • Two Crystal Oscillators, Y1 is for 100MHz Clock, Y2 is for 32.768K RTC Clock.
  • FPGA_FLASH, independent SPI Flash chip for FPGA to store its Bitstream (MCS format).
  • The jumpers, which can be used to configure the voltage level of FPGA_GPIO, as 1.8V, 2.5V, or 3.3V.
  • The FPGA_JTAG interface, which is the on-board USB JTAG programmer for programming the Bitstream of the FPGA.
  • Separated DC 5V power supply and a power switch.
  • The FPGA_PROG button to force the FPGA to re-load the Bitstream from the external Flash.
  • The MCU_FLASH, independent Flash chip for RISC-V core (burned inside FPGA) to store its instruction programs or read-only data.
  • The MCU_JTAG socket, which is the on-board JTAG interface socket for RISC-V Core debugging.
  • The MCU_GPIO connector, for 32 GPIO pins of the SoC.
  • The FPGA_RESET button for PoR reset of the SoC.
  • The MCU_RESET button for System reset of the SoC.
  • The button 1 and button 2.A
  • The LEDs.
  • The Switches.
  • The LEDs and Switches exposed connectors.
  • Up to 126 connectors for other FPGA IOs which can be used by user freely.
