The RL78/I1D CPU Board is a target board used for evaluating RL78/I1D microcontroller operations using E1, the Renesas Electronics on-chip debug emulator with programming function.


  • Incorporates RL78/I1D (R5F117GC)
  • A 20MHz resonator and a 32.768kHz resonator are mounted
  • Equipped with universal area (2.54 mm pitch)
  • Supports both flash memory programming and on-chip debugging (using TOOL0 pin)
  • Highly extendable; peripheral board connectors are equipped with microcontroller pins
  • A 2.54mm pitch through holes for connection and a mounting pad of 1608 size are prepared for to an analog input terminal
