72 MHz Cortex-M4 with floating-point — what it handles
Analog integration — ADC and DAC count
Fifteen 12-bit ADC channels and two 12-bit DAC channels are on-chip. For a sensor-interface design, that ADC count covers multiple analog inputs (current sense, voltage feedback, temperature) without an external multiplexer. The DACs can generate analog setpoints or bias voltages. Combined with the built-in DMA, the ADC can sample and transfer results to memory without CPU intervention — useful for continuous monitoring loops.
Lifecycle status — active production
ST lists the STM32F303CBT7 as Active. The base product number STM32F303 covers a density range, so if the firmware outgrows 128 KB Flash, the pin-compatible STM32F303CCT7 (256 KB) is a drop-in swap without a board respin.
The I²S interface handles audio-class data streams.
