Renesas RZ/T2M dual Arm Cortex-R52 MPU delivers high-precision servo motor control

Built around two Arm Cortex-R52 cores clocked at up to 800 MHz, Renesas RZ/T2M microprocessor units (MPUs) target real-time, high-precision motor control applications such as AC servo drives and industrial robots.

The RZ/T2M microprocessor also supports Ethernet with TSN and functional safety, and has been designed in such a way to reduce the number of external components in order to both decrease the BoM costs and the product size.
