Geehy's First Motor Control Dedicated MCU - APM32F035: Empowering User Products with Rapid Iteration

August 03, 2023 APM32F035 Motor Control

As a 32-bit FoC (Field-Oriented Control) Vector Control MCU, APM32F035 comes with a built-in Vector Computer with various dedicated math accelerators, providing comprehensive support for FoC control algorithms. With outstanding high-efficiency computing and processing speed and rich analog and connectivity features, the APM32F035 enhances motor drive performance and reduces operating costs, enabling domestic motor companies to excel in the "IE3 high-efficiency era."


High-Speed Processing and Efficient Computing


Based on the Arm® Cortex®-M0+ core, operating at a frequency of 72MHz, it supports MDU+Cordic and CRC for superior motor processing performance. With 64KB Flash and 10KB SRAM, it fulfills various embedded motor application algorithm requirements. The MCU includes a single-cycle 32-bit hardware multiplier and integrates the M0CP coprocessor, enhancing the Cortex-M0+ running performance. Its hardware comprises shift units, 32-bit/32-bit dividers, multiply-add operations, square roots, trigonometric functions, and SVPWM (Space Vector Pulse Width Modulation). The MCU also features a dedicated motor PWM with complementary and brake modes, linked with M0CP.


Supporting Various Analog and Connectivity Functions


The APM32F035 boasts built-in high-precision analog and digital peripherals to cater to various functions and high-speed connectivity applications. Alongside conventional peripherals like 12-bit ADC (1Msps), SPI, UART (supporting full-duplex communication), I2C, and CAN, it includes two programmable analog comparators (COMP), four general-purpose operational amplifiers (OP-Amp) for diverse motor current sampling applications, and one temperature sensor. The four general-purpose operational amplifiers offer adjustable gain through external resistors or internal preset gain levels, with a conversion rate of up to 10v/us.


Operating within a temperature range of -40℃ to +105℃ and a voltage range of 2.0 to 3.6V, it supports power-on/power-down reset, sleep, standby, and stop modes, ensuring flexible and balanced overall power consumption. The MCU is equipped with a real-time clock (RTC) and supports an infrared reception function for remote control. It also integrates one 16-bit advanced timer, two 16-bit basic timers, one 32-bit general-purpose timer, two watchdog timers, and one 24-bit down-counter SysTick.
