Its 512 KB of Flash and 64K x 8 of SRAM accommodate a real-time operating system, a communications stack, and a moderate-sized application image; the 64 KB RAM also supports double-buffered ADC data transfers via DMA without stalling the core.
Sixteen 12-bit ADC channels and a single 12-bit DAC let the MCU digitise multiple sensor inputs and output an analogue control signal directly, reducing external op-amp and converter count on the BOM.
The STM32F302RET6 is a closely related sibling in the same STM32F302 family, sharing the same core, Flash density, RAM, and peripheral set. Confirm the temperature grade required for your application before substituting.
The core runs at 72 MHz, which is the maximum clock frequency for this device.
