Renesas RA6E1 Group of 32-bit Microcontrollers (MCUs)

Featuring the high-performance Arm® Cortex®-M33 core with TrustZone

The Renesas RA6E1 group of 32-bit microcontrollers (MCUs) uses the high-performance Arm® Cortex®-M33 core with TrustZone and is built on a highly efficient 40nm process. Supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP) — the RA6E1 MCU series is the perfect entry point into Renesas’ RA Family of microcontrollers.

The Renesas RA6E1 is suitable for entry IoT applications requiring streamlined feature and connectivity integration including Ethernet, and unprecedented performance with 790.75 CoreMark, which are 3.95 CoreMark / Mhz.


  • 200MHz Arm Cortex-M33 with TrustZone
  • 512kB – 1MB Flash memory and 256kB SRAM
  • 8kB Data Flash to store data as in EEPROM
  • 1kB Stand-by SRAM
  • Scalable from 48-pin to 100-pin packages
  • Ethernet with MAC
  • USB 2.0 Full Speed
  • CAN 2.0B
  • Quad SPI
  • SCI (UART, Simple SPI, Simple I2C)
  • SPI/I2C multi-master interface
  • SDHI and MMC


  • Wired Ethernet 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


  • Value optimized feature integration by keeping essential high integration as well as large Flash and RAM for a wide temperature range of Ta = -40/85°C
  • Entry-line connectivity integration with USB 2.0 Full-Speed device, Ethernet, serial communication, CAN, QSPI, and advanced analog
  • Easy migration to mainstream-line with FSP and HW compatibility

FPB-RA6E1: RA6E1 Fast Prototyping Board

The RA6E1 Fast Prototyping Board comes equipped with a R7FA6E10F2CFP microcontroller and is an evaluation board specialized for prototype development for a variety of applications. It has a built-in SEGGER J-Link™ emulator circuit so you can write/debug programs without additional tools. In addition, with Arduino Uno and Pmod™ interfaces included standard and through-hole access to all pins of the microcontroller, and so on, it has high expandability.

Sample software is available to demonstrate the functionality of the RA6E1 MCU and for connecting between the RA6E1 Fast Prototyping Board and various wireless modules or various sensor modules.
