Program memory is 256 KB of Flash, with 40 KB of SRAM — enough headroom for a real-time operating system plus a moderate data buffer for ADC captures or communication stacks. ## 22 analog channels on one die — reducing external converter count This part integrates 22 multiplexed 12-bit ADC channels and two 12-bit DACs. For a design that samples multiple analog inputs — three-phase current sensing plus a position encoder plus a temperature monitor — the on-chip converters eliminate the need for an external ADC or multiple op-amp scaling stages. The DACs can generate analog setpoints or offset trim voltages directly.","metaTitle":"STM32F303RCT7 STM32F3 ARM Cortex-M4 MCU, 72 MHz","metaDescription":"STM32F303RCT7 32-bit ARM Cortex-M4 MCU at 72 MHz with 256 KB Flash, 40 KB SRAM, 22x12-bit ADC, dual 12-bit DAC.
