The company ST showed a new microcontroller STM32L476, which we have soldered in Nucleo development board . Now, ST shows STM32F446.
The microcontroller is based on ARM Cortex M4 to achieve leading performance of 225 DMIPS at 180MHz.
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.
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.
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.
