The CMS32M55xx series are the backbones kernelled of Cmsemicon micro-motor controlling product family, which are widely used in typical motor-driven tools; gardening equipment, standing fans, ceiling fans, vacuum cleaners, range hoods etc.
The CMS32M55xx series are dedicated chips designed by us for advanced motor controlling based on the ARM-Cortex M0.
The operating frequency of this chip is 64MHz, the operating voltage is ranged within 2.1V~5V. The chip possesses with 32K Flash memory, 8K SRAM and 30 GPIOs; 6-channel enhanced PWM which is capable of outputting controllable dead-time with complementary signals; 12-bit high speed ADC with sampling rate @ 1.2Msps; internal 2-channel high-performancing OPA; 2-channel analogue comparator; 32-bit hardware divider which only needs 6 system clock. As for the communication ports, the chip provides two UART and one for SPI and I2C.
The chip we design fulfils all industrial grade requirements with operating temperature -40~-105 ℃, multiple integrated drivers (3P+3N, 6N) which lowers the cost of peripheral components and the BOM.
Additionally, the chip possesses the IEC60730 safety check library, which provide a faster authentication for users during a CLASS B check.
This series are packaged in the forms of SSOP24, QFN40 & LQFP48.

As people's awareness of energy saving and emission reduction increases, range hoods are a product that is frequently used in home life, and the market needs high-efficiency motors and motor control solutions. Cmsemicon develops an FOC control scheme for this application, which improves the operating efficiency of the motor while effectively reducing the operating noise and vibration of the motor.
Aiming at the application of air purifiers in the home, medical and industrial fields, Cmsemicon has launched a cost-effective air purifier motor control solution. Using SVPWM space voltage vector modulation technology, it has smaller harmonic components and torque ripple, and the peripheral circuit is streamlined to provide a complete solution.
