Artery Technology's AT32M412/M416 motor-specific series ARM^® Cortex^®-M4 microcontrollers feature a CPU operating speed of up to 180MHz, along with up to 128+28KB flash memory and 16KB SRAM. Their CPU computing power, as well as flash and SRAM capacities, are all larger than those of products in the same class, meeting the needs of product upgrading and iteration. These microcontrollers integrate abundant on-chip peripheral resources, including 2 USARTs, 1 CAN-FD, 2 I²Cs, 2 SPI/I²Ss, 6 16-bit general-purpose timers (including 1 advanced PWM timer for motor control), 2 basic timers, and 1 low-power ERTC. They also extend to 2 12-bit 18-channel high-speed ADCs with a sampling rate of up to 2Msps, 2 6-bit DACs, 2 comparators (CMP), 4 operational amplifiers (OP) (supporting PGA mode), and up to 46 fast GPIO ports. The chip provides rich interconnection functions between most peripherals, making the AT32M412/M416 series particularly suitable for motor drive-related applications.
