STM32F446 product line enables high performance and rich connectivity into a highly integrated and energy efficient product, starting from 256K Flash.

It leverages ST’s proprietary ART Accelerator?, smart architecture, advanced Flash technology and its embedded ARM Cortex-M4 core to achieve leading performance of 225 DMIPS and 608 CoreMark?  at 180MHz executing from embedded Flash.

Efficient simultaneous communication via multiple interfaces enables smarter and more interactive industrial, scientific, medical, and Internet-of-Things (IoT) applications, while the advanced process technology, together with dynamic voltage scaling, extensive clock gating and flexible sleep modes allow for significant power savings.

  • Performance: At 180 MHz, the STM32F446 delivers 225 DMIPS/608 CoreMark performance executing from Flash memory, with 0-wait states thanks to ST’s ART Accelerator. The DSP instructions and the floating point unit enlarge the range of addressable applications.
  • Power efficiency: ST’s 90 nm process, ART Accelerator and the dynamic power scaling enables the current consumption in run mode and executing from Flash memory to be as low as 200 μA/MHz at 180 MHz. In Stop mode, the power consumption is 50 μA typical.
  • Integration:
    • 2 dedicated audio PLL, SPDIF input, 3 half duplex I2S , and 2 serial audio interfaces (SAI) supporting full duplex I2S as well as time division multiplex (TDM) mode.
    • Up to 20 communication interfaces (including 4x USARTs plus 2x UARTs running at up to 11.25 Mbit/s, 4x SPI running at up to 45 Mbit/s, 3x I2C with a new optional digital filter capability, 2x CAN, SDIO, HDMI CEC and camera interface)
    • Two 12-bit DACs, three 12-bit ADCs reaching 2.4 MSPS or 7.2 MSPS in interleaved mode Up to 17 timers: 16- and 32-bit running at up to 180 MHz 
    • Easily extendable memory range using the flexible 90 MHz memory controller with a 32-bit parallel interface, and supporting Compact Flash, SRAM, PSRAM, NOR, NAND and SDRAM memories 
    • Cost effective NOR flash extension thanks to the 90MHz Dual quadSPI interface supporting memory mapped mode

The STM32F446 product line provides from 256-Kbyte to 512-Kbyte Flash, 128-Kbyte SRAM and from 64 to 144 pins in packages as small as 3.85 x 3.728 mm.
