Renesas RA8T1 Series of Microcontrollers (MCUs)

480 MHz Arm® Cortex®-M85 based Motor Control Microcontroller with Helium™ and TrustZone®

Renesas features their RA8T1 group of 32-bit microcontrollers (MCUs) based on an up to 480MHz Arm Cortex-M85 core with Helium Technology and TrustZone. The MCUs offer peripheral features optimized for motor or inverter controls.

The RA8T1 product family integrates up to 2MB large Flash memory, 1MB SRAM including TCM, PWM timers, analog features, multiple connectivity features, and also supports advanced security features and safety functions.

Renesas’ RA8T1 group enables advanced motor control or additional functions on user systems through its high performance and abundant integrated features.

The RA8T1 Group supports the Flexible Software Package (FSP) and partner ecosystems, as well as motor control evaluation kits, software, and tools.
