At this frequency the Flash requires one wait state for zero-wait access; the PLL can be configured from the internal or an external oscillator."},{"question":"What are the alternatives to STM32F303C6T6?","answer":"Within the STM32F303 family, pin-compatible 48-LQFP variants with larger Flash (e.g., 64 KB or 128 KB) share the same footprint and peripheral set, providing a drop-in upgrade path. Cross-vendor alternatives would require a board respin due to differences in pinout and register maps."},{"question":"Is STM32F303C6T6 compatible with STM32F103?","answer":"The STM32F303C6T6 and STM32F103 are not pin-compatible — they belong to different STM32 families with different peripheral maps and register layouts. Software migration requires rewriting peripheral drivers; hardware requires a new PCB layout. The STM32F303 is a closer match for designs needing the Cortex-M4 FPU and mixed-signal converters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F303C6T6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F303C6T6 when reusing this data.
