Geehy Launches Encoder MCU for High-Precision Motion Control

Geehy has expanded its industrial microcontroller portfolio with the launch of the G32R430 series - a purpose-built encoder MCU designed for high-precision motion control applications. Unlike general-purpose microcontrollers, the G32R430 focuses on real-time encoder signal processing, making it suitable for servo drives, robotics, and industrial automation systems.

At the core of the MCU is a 128 MHz Arm Cortex-M52 processor based on the Armv8.1-M architecture. The device integrates tightly coupled instruction and data memory along with a high-speed cache to ensure deterministic performance for time-critical control loops and stable operation at low motor speeds.

One of the key differentiators of the G32R430 is its hardware-accelerated ATAN instruction, implemented in a dedicated math unit. This allows fast and accurate electrical angle calculations with latency below one microsecond and angle precision better than 0.0001°, significantly reducing CPU load compared to software-based implementations.

For signal acquisition, the MCU integrates dual 16-bit ADCs supporting differential and synchronous sampling, with effective resolution up to 13.5 bits. Additional on-chip peripherals include a secondary ADC, DAC outputs, analog comparators, and a temperature sensor, helping reduce the need for external analog components.

By treating encoder processing as a core function rather than an add-on, Geehy’s G32R430 MCU aims to simplify system design while improving accuracy, responsiveness, and reliability in demanding motion control applications.
