72 MHz Cortex-M4 with mixed-signal front-end
The STM32F373V8T6: What sets it apart in the STM32F3 lineup is the analog peripheral density: three 16-bit sigma-delta ADCs alongside a 12-bit SAR ADC and three 12-bit DACs — enough simultaneous-sampling channels for a multi-sensor control loop without external converters. A bare-metal scheduler or a minimal FreeRTOS config leaves room for the application stack and the HAL overhead.
Connectivity and I/O for fieldbus and sensor hubs
The DMA engine offloads the Cortex-M4 during high-rate data transfers from the ADCs or serial ports.
Package and power supply flexibility
The industrial temperature grade (-40°C to 85°C) covers factory-floor automation, outdoor telecom enclosures, and under-hood automotive auxiliary modules that don't require AEC-Q100 qualification.
