The STM32F373CCT6 from STMicroelectronics is a mixed-signal microcontroller built on the ARM Cortex-M4 core with hardware floating-point unit, reaching 72MHz operation. What distinguishes this device from standard STM32 models is its exceptional analog peripheral set: three 16-bit sigma-delta ADCs (SDADCs) provide high-precision measurement capability with up to 21 single-ended or 11 differential input channels, while three 12-bit DACs enable simultaneous generation of multiple analog outputs. The two fast comparators support real-time threshold detection. These analog capabilities, combined with the Cortex-M4’s DSP instructions and FPU, make the STM32F373CCT6 an ideal single-chip solution for applications requiring precision analog signal processing and digital control.

The STM32F373CCT6 integrates an ARM Cortex-M4 processor core with a rich set of analog and digital peripherals connected through a multi-bus matrix (AHB/APB). The Cortex-M4 executes instructions from 256KB Flash with zero-wait-state access up to 24MHz (with prefetch enabled for higher speeds), and accesses data in 32KB SRAM with hardware parity protection. The three SDADCs use oversampling and decimation to achieve 16-bit resolution, each with its own reference and input multiplexer, enabling simultaneous multi-channel measurement. The three 12-bit DACs can be driven by DMA for waveform generation without CPU intervention. The 12-bit SAR ADC provides fast single conversions for general-purpose measurement. All peripherals can communicate through the 12-channel DMA controller, minimizing CPU overhead. Power management includes VBAT domain backup for RTC and registers, with Sleep/Stop/Standby modes for low-power operation.
