Pre-replacement Checklist (MCU)
- Core architecture & frequency class
- Flash/RAM density & memory map
- Peripheral register compatibility (UART/SPI/ADC mapping drives porting effort)
- Pin compatibility (LQFP/QFN pin-by-pin, incl. alternate functions)
- Firmware porting effort (register/stdlib/HAL level)
- Toolchain, programmer & debugger support
- Supply longevity & lifecycle (EOL risk)
These are standard checkpoints for this product type. Verify each item and pilot-test before full switch-in. Ask us for samples, a replacement assessment report or FAE support - free samples and validation assistance provided.
