The MultiZone® IoT Firmware is the quick and safe way to build secure IoT applications with RA6M3 microcontrollers. It provides secure access to IoT clouds, real-time monitoring, secure boot, and remote firmware updates. The built in Trusted Execution Environment provides hardware enforced separation to shield the execution of trusted applications from untrusted third party libraries.


  • Fully integrated with Renesas e2 studio and Flexible Software Package (FSP)
  • Safe and quick way to add high grade security and separation — Up to 4 "secure worlds"
  • Rapid development: Pre-integrated TEE, TLS/ECC, TCP/IP, MQTT, RTOS, FSP
  • Easy retrofit of existing hardware and software — No need for a system redesign
  • Convenient MPU based alternative to an Arm® TrustZone® upgrade
  • Convenient software license priced per design — No royalties, no GPL contamination
