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 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 RA4M3 is suitable for IoT applications requiring vast communication options, future proof security, large embedded RAM, and low active power consumption down to 119µA/MHz running the CoreMark® algorithm from Flash.

Features

  • 100MHz Arm Cortex-M33 with TrustZone
  • Secure element functionality
  • 512kB - 1MB Flash memory and 64kB SRAM with parity and 64kB SRAM with ECC
  • 8kB Data Flash to store data as in EEPROM
  • 1kB Stand-by SRAM
  • Scalable from 64-pin to 144-pin packages
  • Capacitive touch sensing unit (CTSU)
  • USB 2.0 Full Speed
  • CAN 2.0B
  • Quad SPI
  • SCI (UART, Simple SPI, Simple I2C)
  • SPI/I2C multi-master interface
  • SDHI and MMC

Applications

  • Enhanced security (fire detection, burglar detection, panel control)
  • Metering (electricity, automated meter reading)
  • Industry (robotics, door openers, sewing machines, vending machines, UPS)
  • HVAC (heating, air conditioning, boiler control)
  • General purpose
