New Product Introduction

Renesas RA4M3 MCU Group

RA4M3 - 100MHz ARM Cortex M33 with TrustZone, Security and Memory enhancements

Renesas RA4M3 microcontroller - front side of the product sample

With the RA4M3 group, Renesas expands their Renesas RA4 series. It is based on the latest Arm Cortex-M33 Core with TrustZone with increased 1 MB on-chip Flash and 128KB on-chip RAM. The integrated Standby RAM along with the low power consumption of the Renesas 40nm process is the optimum for low power applications. The memory block swap feature, new on the RA4 series, in conjunction with the Security Crypto Engine is making the RA4M3 the best choice for applications where in field firmware updates are required. 

The enhanced integrated Security Crypto Engine with several cryptography accelerators, key management support, tamper detection and power analysis resistance in concert with the newly implemented Arm TrustZone is making the devices the best choice in the market for connected applications. The memory can be extended with Quad-SPI, Octa-SPI and SD-Card interface for more memory hungry applications.
