Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer's current production status and lifecycle stage, as availability may vary. Ensure compatibility with the required operating temperature range and voltage specifications for the target application environment before procurement.
Selection Notes
Select this component for designs requiring a balance of processing power and analog integration. The 48 MHz speed and 12-bit ADC suit moderate-performance tasks. Consider the TQFP-48 package constraints for PCB layout. Evaluate power consumption requirements against the available sleep modes to ensure efficiency meets system goals.
Part Context
This part belongs to the Infineon PSoC 4200M family, designed for cost-sensitive embedded applications. It combines a standard ARM Cortex-M0 processor with Cypress's proprietary programmable analog fabric. This architecture allows customization of peripheral functions without external components, reducing bill-of-materials complexity.
Replacement Considerations
Check for direct pin-compatible substitutes within the same PSoC 4200M series with matching memory sizes. Verify that any alternative maintains the TQFP-48 footprint and identical electrical characteristics.
