Eligible Parts

The RL78 is Renesas Electronics’ next-generation microcontroller family that combines both the 78K and R8C families to deliver low power and high performance. It is designed specifically for ultra low-power applications enabling customers to build compact and energy-efficient systems at a lower cost.

The RL78/G13 Demonstration Kit (“RDK”s) is optimized for low power and features a great mix of peripherals! It is based on the 78K0R CPU core and can be applied to all sorts of consumer and industrial applications. Optimized for low-power operation, this development kit runs with a 16-bit, 32-Mhz RL78G13 MCU @ 40.6 DMIPS. RDKs may be purchased at and

This board is jam packed with a 3-axis accelerometer, stereo audio output and on-board speaker, silicon microphone input and temp sensor from Analog Devices, a 96 × 64 graphics LCD from Okaya, crystals by NDK, a Total Phase Beagle 12C/SPI debug interface, expansion headers, a micro SD card slot, light sensor, and more!

Software for this development kit is supported by the IAR RL78 Embedded Workbench, as well as a Micrium full uC/Probe license. The RDK comes fully loaded with the Embedded Workbench, 16KB Kickstart edition. To request a full license of the IAR Embedded Workbench, email and include your contact information with email, company name if applicable, and it should indicate that it is for the RL78 Green Energy Challenge. The full license expires on September 1, 2012.
