STMicroelectronics – 32-bit MCU, STM32F446 with FPU implements full set of DSP instructions


High performance – from 256KB Flash, measuring 3.728 mm x 3.85 mm

The STM32F446 microcontroller provides high-performance processing with a built-in Floating-Point Unit (FPU).

The device has a 32-bit ARM® Cortex®-M4 core operating at a frequency of up to 180MHz. The core’s FPU 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 which enhances application security.

The STM32F446 features three 12-bit ADCs, two DACs, a low-power real-time clock, and 12 general-purpose 16-bit timers, including two PWM timers for motor control.

  • Hi-Speed and Full-Speed USB2.0 interfaces
  • LCD parallel interface
  • 8- to 14-bit parallel camera interface operating at up to 54Mbytes/s
