Description
The RA8T2 is an ASSP microcontroller (MCU) featuring a 1GHz Arm® Cortex®-M85 processor, engineered for industrial motor control applications that require high real-time performance and high-precision control. Built on the advanced 22nm ULL process, the RA8T2 is available in both single and dual-core options. The dual-core variant is embedded with a Cortex-M33 core to efficiently separate real-time processing from the other processing tasks to further enhance the system performance.
The RA8T2 ASSP MCU combines high-speed operation, large-capacity memory, a PWM timer for motor control, and analog functions – all on a single chip. A dual-channel Gigabit Ethernet controller with switch function and an optional EtherCAT® slave controller enables synchronous networks in industrial fields. The RA8T2 is available in three package types: BGA-224, 289, and HLQFP-176.
