R0K0F4022C000BR is a CPU board which includes the V850E2/ML4 (V850E2M core, 200MHz at 3.3V, and 216-pin package).





  • This board includes a LAN connector to enable development and evaluation for the software using the Ethernet (100Base-TX).
  • This board includes a USB host connector (Series A receptacle) and USB function connector (Series Mini-B receptacle) to enable development and characteristic evaluation for the software using the V850E2/ML4 USB.
  • This board includes a CAN port connector (3-pin, pin header) to enable development and evaluation for the software using the CAN.
  • The V850E2/ML4 external bus signal and the on-chip peripheral function pins are connected to the application header through-holes to enable users to develop expansion boards.
  • A debug connector (14-pin) which can be connected to the Renesas E1 emulator is provided to this board.
