RL78 Family

Renesas Tools for the RL78

Renesas Electronics and selected partners offer a comprehensive suite of hardware and software tools for the rapid evaluation and development of embedded systems built with RL78 MCUs.

RL78 Renesas Demonstration Kit (RDK) details here

Hardware development tools

A low-cost on-chip debugging emulator and a full-spec emulator are available. You can select the environment that best matches your debugging needs.

E1 on-chip debugging emulator

The E1 provides a wide range of support for Renesas microcontrollers at low cost.  This emulator connects to the RL78 MCU’s through its proprietary single-wire interface for efficient on-chip debugging.
