AT32M416 — motor-control MCU family in the Artery AT32 portfolio
The AT32M416 is a motor-control MCU in Artery Technology's 32-bit AT32 microcontroller portfolio. It runs at up to 180 MHz system clock, with up to None KB of on-chip Flash and 16 KB of SRAM, built around a high-efficiency ARM Cortex-M core.
The family is aimed at field-oriented control (FOC) of BLDC and PMSM motors, pairing a high system clock with advanced timers, comparators and op-amps. Offered in TSSOP247.8x4.4 mm, QFN324x4 mm, LQFP327x7 mm, QFN486x6 mm, LQFP487x7 mm packaging, one design can scale across pin-count variants while keeping the core software identical.
