STM32F446ZET6原装MCU的描述：

Arm? Cortex?-M4 32-bit MCU+FPU, 225 DMIPS, up to 512 KB Flash/128+4 KB RAM, USB OTG HS/FS, seventeen TIMs, three ADCs and twenty communication interfaces

The STM32F446xC/E devices are based on the high-performance Arm? Cortex?-M4 32-bit RISC core operating at a frequency of up to 180 MHz.

The Cortex-M4 core features a floating point unit (FPU) single precision supporting all Arm? single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) that enhances application security. The STM32F446xC/E devices incorporate high-speed embedded memories (Flash memory up to 512 Kbytes, up to 128 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.

All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces.
