Procurement Notes
Verify the specific ordering suffix against official Infineon or Cypress documentation to confirm package type and temperature grade. Ensure compatibility with PSoC Designer software versions for development. Confirm RoHS compliance status if required by your manufacturing standards before finalizing procurement orders.
Selection Notes
Select this component when a flexible architecture combining analog and digital capabilities is needed. It is suitable for designs requiring configurable peripherals to reduce bill-of-materials count. Consider the 16 KB Flash limit for complex firmware requirements and verify GPIO availability matches the pinout configuration.
Part Context
This part belongs to the CY8C22x45 series within the broader PSoC 1 family. These devices are designed to replace multiple discrete components with a single programmable chip. The series emphasizes low cost and high integration for embedded control applications.
Replacement Considerations
Check for CY8C22545 variants with different package options such as SOIC or QFN if lead-free or space constraints differ. Verify functional equivalence with CY8C21x45 series parts if fewer GPIOs are sufficient.
