GR-PEACH is an Mbed enabled platform which combines the advantages of the Mbed ecosystem and Arduino UNO form factor



The RZ/A1H includes an Arm® Cortex™-A9 processor along with the integrated peripheral functions required to configure a system.

The RZ/A1H includes a 32-Kbyte L1 instruction cache, a 32-Kbyte L1 data cache, and a 128-Kbyte L2 cache. This LSI also includes on-chip peripheral functions necessary for system configuration, such as a 10-Mbyte large-capacity RAM, 128 Kbytes data-retention RAM(shared by the large-capacity RAM), various timer function, realtime clock, serial communication interface(UART), I2C bus interface and graphics related functions etc.

TES Guiliani

The C++ HMI Framework “Guiliani” by TES Electronic Solutions allows rapid implementations of smooth, intuitive and high-performance GUIs on cost and energy efficient embedded devices. The Guiliani SDK for GR-PEACH can be downloaded from the following link:

The Guiliani SDK for GR-PEACH is perfectly optimized for the RZ/A microprocessor family and includes WYSIWYG PC Editor "GSE", example GUI applications and everything else you need to set up your own project and create stunning GUIs. Furthermore, a world-wide, unlimited and perpetual production-license for Guiliani-Lite is offered free-of-charge via the Prepaid by Renesas program. For more details on example GUI applications and Prepaid by Renesas program, please see the following links respectively:

Please note that Prepaid by Renesas program can be applied to Mbed OS although there is no description on that platform there. This page will be updated shortly.
