Renesas RA4M2

The Renesas RA4M2 group uses the high-performance Arm^® Cortex^®-M33 core with TrustZone^®. In concert with the Secure Crypto Engine it offers Secure Element functionality. It offers rich connectivity with USB 2.0 FS, SDHI, QSPI, and advanced analog.

The RA4M2 is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP), built on FreeRTOS—and is expandable to use other RTOSes and middleware. The RA4M2 is suitable for IoT applications requiring future proof security, large embedded RAM, and low active power consumption down to 81uA/MHz running CoreMark^® from Flash.
