100MHz Arm Cortex-M33 TrustZone, High Integration With Lowest Active Power Consumption

Order Now

Overview

The Renesas RA4M2 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 RA4M2 is built on a highly efficient 40nm process and 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 vast communication options, future proof security, large embedded RAM, and low active power consumption down to 81µA/MHz running the CoreMark® algorithm from Flash.

  3. RA4M2, RA4M3, RA6M4, RA6M5: Is it possible to change the Trustzone boundaries via OTA?

    ... change the IDAU settings in firmware and it is not possible to be manipulated during remote update (e.g. OTA). So the answer is no, the Trustzone boundaries cannot be changed during OTA.   Resources: Securing Data at Rest Using the Arm® TrustZone®   Suitable Products RA4M2,RA4M3,RA6M4,RA6M5
