- SRAM:
- up to 96KB
Compatibility & sourcing notes
Same LQFP footprint and largely register-compatible — a common second source when STM32F103 is short. Core runs to 108MHz (vs 72MHz), so recheck clock, Flash wait-states, and some HAL settings when porting.
The two share a footprint and interface and can usually be swapped directly; before mass production, still confirm voltage, density, and timing against both datasheets.
