Product Description

The G32R430, Geehy's first encoder-dedicated MCU, is designed for high-precision motion control and position feedback applications. Based on the Arm® v8.1-M Cortex-M52 core operating at 128MHz, it integrates a self-developed ATAN electrical angle calculation instruction extension for hardware-accelerated trigonometric computation. This achieves ATAN accuracy better than 0.0001° and encoder electrical angle output latency This achieves ATAN accuracy better than 0.0001° and encoder electrical angle output latency below 1μs.

The G32R430 integrates high-sensitivity analog peripherals, including 16-bit high-precision ADCs, 12-bit ADCs, 10-bit DACs, and an on-chip temperature sensor, ensuring reliable signal acquisition in harsh environments. It also integrates high-speed communication interfaces and supports Tamagawa, BiSS-C, SSI, and SPI encoder protocols, significantly improving position feedback accuracy and real-time performance in servo systems.

With an ultra-low-power architecture and microsecond-level fast wake-up, the G32R430 delivers rapid real-time response while maintaining excellent energy efficiency. It is well-suited for industrial servo systems, humanoid robots, and intelligent automation equipment.
