RA4M3 100 MHz Arm® Cortex®-M33 TrustZone®

Author: EIS Release Date: Mar 4, 2021


Renesas' RA4M3 MCUs offer high integration with rich connectivity options

Image of Renesas' RA4M3 100 MHz ArmⓇ CortexⓇ-M33 TrustZone® The Renesas RA4M3 group of 32-bit microcontrollers (MCUs) uses the high-performance Arm Cortex-M33 core with TrustZone. In concert with the secure crypto engine, it offers secure element functionality. The RA4M3 is built on a highly efficient 40 nm process. It 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 RA4M3 is suitable for IoT applications requiring vast communication options, future proof security, large embedded RAM, and low active power consumption down to 119 µA/MHz running the CoreMark® algorithm from Flash.
