STM32F446ZC | 32-bit Arm Cortex MCUs
STM32F446ZC
High-performance foundation line, ARM Cortex-M4 core with DSP and FPU, 256 Kbytes Flash, 180 MHz CPU, ART Accelerator, Dual QSPI
Overview
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 which supports 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) which enhances application security.
The STM32F446xC/E devices incorporate high-speed embedded memories (Flash memory up to 512 Kbyte, up to 128 Kbyte 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.
