The 72 MHz core with hardware FPU handles single-cycle MAC operations, which matters for FOC motor control or digital power-loop compensation. The flash wait state needs bumping to 1 before you cross about 48 MHz, or the first branch after a tight loop hard-faults — standard Cortex-M4 practice. The internal oscillator gets you running, but for CAN or precision timing you will want an external crystal on the HSE pins. ## Supply rails and decoupling The 64-LQFP has a central ground paddle — make sure your PCB layout includes a via stitch under the package to pull heat out if the part draws more than 100 mA continuous. Decouple each VDD/VSS pair with a 100 nF ceramic within 3 mm of the pin; a 4.7 µF bulk cap on the main rail handles low-frequency transients. It fits factory automation, motor drives, outdoor telecom, and HVAC controller boards — anything that sees a cold start or a warm cabinet but not engine-bay heat. ## Lifecycle and supply reality That means no last-time-buy pressure for current production.","metaTitle":"STM32F303R6T6 STM32F3 ARM Cortex-M4 MCU, 72 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F303R6T6 32-bit ARM Cortex-M4 MCU, 72 MHz core, 32 KB Flash, 16 KB SRAM, 51 I/O, 64-LQFP.

The F3 uses a Cortex-M4 with FPU and a different peripheral map (including a 12-bit ADC vs the F103's 12-bit ADC with different channel routing). A board designed for an STM32F103 would need schematic and layout changes to use the F303."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F303R6T6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F303R6T6 when reusing this data.
