72MHz Cortex-M4 with mixed-signal ADCs
The STM32F373RBT6: The 128 KB of on-chip Flash and 24K x 8 SRAM provide enough headroom for a moderate application stack and data buffers. A standout feature is the data converter block: three 16-bit sigma-delta ADCs alongside a 12-bit SAR ADC and three 12-bit DACs. The sigma-delta channels are suited for precision measurement — think current sensing in motor drives or strain-gauge readout — where the higher resolution captures low-level signals without an external amplifier.
