Product details

72 MHz Cortex-M4 with DSP and FPU — what it buys you

The STM32F303RDT7: The ARM Cortex-M4 core runs at 72 MHz with DSP and FPU. 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.

Frequently asked questions

Can STM32F303RDT7 replace STM32F303RCT6?

The STM32F303RDT7 is a pin-compatible upgrade from the STM32F303RCT6 within the same 64-LQFP package, doubling the Flash from 256 KB to 384 KB. Both share the same 72 MHz Cortex-M4 core, peripheral set, and supply range. Firmware migration requires updating the memory map and linker script for the larger Flash, but no board layout change.
