Procurement Notes
Verify the specific ordering suffix L423T against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and voltage levels for your specific application design before finalizing procurement.
Selection Notes
Select this component when a scalable platform combining mixed-signal capabilities with an Arm Cortex-M0 processor is required. It is suitable for designs needing programmable logic, high-performance analog conversion, and secure embedded control within a compact surface-mount footprint.
Part Context
This part belongs to the PSoC 4200L family, which extends the standard PSoC 4 architecture with enhanced low-power features. It maintains binary upward compatibility with higher-performance Cortex-M3 and M4 processors, allowing for future design scalability without significant code modifications.
Replacement Considerations
Check the PSoC 4200 family selector guide for alternative pin counts or memory sizes. Verify that any substitute maintains the same 48-TQFP package dimensions and electrical characteristics to ensure mechanical and functional interchangeability.
