Renesas Electronics RA6T2 Motor Control MCUs

240MHz Arm® Cortex®-M33 TrustZone®, High Real-time Engine for Motor Control

The Renesas RA6T2 Group is the second RA ASSP product targeting for motor and inverter control solutions. The RA6T2 combines an Arm Cortex®-M33 with a hardware accelerator for motor control and high-speed flash memory for high-speed real-time performance at 240MHz.

The RA6T2 series of MCUs also realize next-generation high-speed, high-response motor algorithms and improve parallel processing performance such as other communication processing. The Flexible Software Package (FSP) and the Arm Partner Ecosystem ensure an easy-to-use solution for highly efficient and accurate motor and inverter control.


  • 240MHz Arm® Cortex®-M33 with TrustZone®
  • 256KB -512KB Flash memory and 64KB SRAM with ECC
  • 16KB Data Flash to store data as in EEPROM
  • Scalable from 48-pin to 100-pin packages
  • HW accelerators for motor control calculation
  • 12-bit ADC
  • 12-bit DAC
  • Programmable Gain Amp
  • High speed comparator
  • PWM timer
  • CAN FD (option)
  • SCI (UART, Simple SPI, Simple I2C)
