Renesas is expanding the Renesas RA4 series with RA4M3 group based on latest Arm® Cortex®-M33 core with TrustZone. The integrated standby RAM along with low power consumption of Renesas 40nm process is optimum for low power applications. The memory block swap feature, new on the RA4 series, in conjunction with security crypto engine is making 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 Renesas RA MCU family makes it easy to develop IoT edge devices with embedded artificial intelligence (e-AI), using the new Flexible Software Package (FSP), fast-start software for security and connectivity and development tools from Renesas and the Arm partner ecosystem.
