The Renesas Demonstration Kit (RDK) for RL78/G13 is an evaluation and demonstration tool for Renesas RL78/G13 microcontrollers. The goal is to provide the user with a powerful debug and demonstration platform targeted at common applications. To aid in the evaluation of the RL78 family of microcontrollers, we include IAR's Embedded Workbench Kickstart Edition for the RL78. This full featured toolsuite allows for up to 16KB of application code to be implemented on the RL78/G13 RDK. To facilitate programming the RDK, the IAR tools support the Renesas TK Debugger which is on-board the RL78/G13 RDK.

What is PMODTM?

PMODsTM are small I/O interface boards that offer an ideal way to extend the capabilities of our MCU evaluation and demo boards. It can be found on RDKs and RSKs. PMODs communicate with system boards using 6, 8 or 12-pin connectors. Pmods include sensors, I/O, data acquisition & conversion, connectors, external memory, and more.

  • Convenient low pin-count daughter card format
  • Peripheral Module: PMOD
  • Trademarked by Digilent Inc. (
  • Low cost (connector/cards)
  • Open and royalty free
  • Typically 12-pin connector
    • 6-pin format also available
  • 2 slots in each RDK
    • UART/SPI/I2 C
  • Provide power to cards
