Description
The Renesas RA6T2 Group is the second RA ASSP product targeting 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. It can also realize next-generation high-speed, high-response motor algorithms and improve parallel processing performance such as other communication processing. In total, we have 20 different part names using 5 different package types. 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.
