The 384 KB Flash and 80 KB SRAM support moderate application stacks. ## Analog front-end: 22 ADC channels and two DACs 22 multiplexed 12-bit ADC inputs and two independent 12-bit DAC outputs are available. ## Connectivity and peripheral set for mixed-signal control The CAN interface suits industrial fieldbus and automotive body-electronics nodes. The I²S port connects to external audio codecs or serial ADCs. ST lists the STM32F303RDT7 as Active (current production). For volume BOMs, this is a single-source item — no official second-source alternate is published.","metaTitle":"STM32F303RDT7 STM32F3 ARM Cortex-M4 MCU, 72MHz, 384KB Flash","metaDescription":"STM32F303RDT7 32-bit ARM Cortex-M4 MCU at 72MHz with 384KB Flash, 80KB SRAM, 22x12-bit ADC, 2x12-bit DAC.
