Featured Product


The Rl78 family of microcontrollers (MCUs) combines advanced low power technology, outstanding performance, and the broadest line-up in its class for the most demanding 8 and 16-bit embedded applications.  The RL78 MCUs' innovative "Snooze" mode achieves ultra-low power by allowing ADC operation and serial communication, all while the CPU is turned off.  This makes the RL78 MCUs best in class for low power applications.

Eval Boards



The Renesas Demonstration Kit (RDK) for RL78G13 is an evaluation and demonstration tool for Renesas RL78G13 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 RL78G13 RDK.  To facilitate programming the RDK, the IAR tools support the Renesas TK Debugger which is on-board the RL78G13 RDK.
