mbed™ board GR-PEACH
The RZ/A1H deployment made in Renesas Electronics Corporation
The world’s first mbed™-adaptive board using “ARM®Cortex®-A series”


As board of “ARM®Cortex®-A series” use, we participate in ARM®mbed™ project for the first time in the world
We provide embedded system environment that is high efficiency, tall handloom ability that was not able to be realized easily in “Cortex-M”.
Merit of mbed user by RZ/A1H adoption
Microcomputer that RZ/A1H has Cortex-A9 (industry ratio approximately 2 times) which is high-performance CPU of 400MHz, large-capacity built-in RAM (industry ratio approximately 30 times) of 10MB, camera input / graphics output / audio system function.
By CMSIS correspondence for Cortex-M, we can transfer software assets of “Cortex-M” to “Cortex-A9”.


Embeds ARM Cortex-A RZ/A1H (R7S721001VCBG)
Arduino UNO pin compatibility supports various shields.


GR-PEACH board equipped with LAN connector (RJ-45) and connectors for Arduino UNO compatible pins and service pins.
