FU6832N is a high-performance motor drive dedicated chip integrating motor control engine (ME) and 8051 core. ME integrates many hardware modules such as FOC, MDU, LPF, PI, SVPWM/SPWM, etc., and can automatically complete motor FOC/BLDC operation control by hardware ; The 8051 core is used for parameter configuration and daily transaction processing, and the dual-core parallel work realizes various high-performance motor control. Among them, most of the instruction cycles of the 8051 core are 1T or 2T, and the chip integrates high-speed operational amplifiers, comparators, Pre-drivers, high-speed ADCs, high-speed multipliers/dividers, CRC, SPI, I2C, UART, LIN, various TIMER, PWM and other functions, built-in high-voltage LDO, suitable for square wave, SVPWM/SPWM, FOC drive control of BLDC/PMSM motors.

FU6832N package form: FU6832N (QFN32).
