STM32F446 in STM32 Family

The STM32F446 sub-family from STMicroelectronics represents a high-performance branch of the Cortex-M4 portfolio, engineered to bridge the gap between standard microcontrollers and high-end application processors. Running at 180 MHz, these MCUs integrate an Adaptive Real-Time (ART) accelerator and a floating-point unit (FPU). They are specifically designed for applications requiring complex signal processing, advanced audio capabilities, and robust motor control while maintaining the power efficiency characteristic of the STM32F4 series.

Variants in the STM32F446 line are primarily distinguished by flash memory density, ranging from 256 KB to 512 KB, and package pin counts. Package options include LQFP64, LQFP100, and UFBGA144. Higher pin-count variants provide access to the full flexible memory controller (FMC) bus and additional GPIOs for complex peripherals, whereas smaller packages like the WLCSP81 target space-constrained mobile or wearable designs.
