The STM32F446VCT7 is an STM32F4-series ARM Cortex-M4 MCU with a single-precision FPU, clocked at 180 MHz. That core speed, combined with the DSP instruction set, lets it handle real-time control loops and audio processing without a separate DSP chip.
Peripheral set for system-level integration
This part carries a connectivity set that reduces external IC count: CANbus for industrial or automotive networks, USB OTG for dual-role host/device, SAI for I²S audio, and SPDIF-Rx for digital audio input. Brown-out detect, POR, and a low-voltage detector are built in, so an external supervisor is optional.
The internal oscillator means you can bring up UART bootloading without an external crystal, though the PLL accuracy for USB will want a 25 MHz or 8 MHz external resonator.
STMicroelectronics lists the STM32F446VCT7 as Active. No last-time-buy or end-of-life notice applies to this order code as of the current product status. For new designs, the active lifecycle means no forced redesign from obsolescence in the near term.
