Procurement Notes

Verify current availability status as this part may be subject to end-of-life notifications. Confirm package type and suffix requirements against specific design constraints. Ensure compatibility with existing development tools such as PSoC Designer. Check for any alternative recommendations from the manufacturer due to product lifecycle changes.

Selection Notes

Select this component when a highly configurable mixed-signal solution is required within the PSoC 1 ecosystem. Consider the resource allocation of digital and analog blocks relative to application complexity. Evaluate the need for CapSense functionality if touch interfaces are involved. Assess power consumption requirements against the available voltage options and sleep modes.

Part Context

This device belongs to the CY8C28xxx subgroup of the PSoC 1 family, characterized by a full feature set of resources. It shares architectural similarities with other members like the CY8C28645 but differs in pin count and specific I/O configurations. The family emphasizes programmability to replace multiple discrete components.

Replacement Considerations

Consult official documentation for direct substitutes within the CY8C28xxx series. Verify pin-to-pin compatibility and resource equivalence before transitioning. Review product change notifications for any functional updates or obsolescence notices affecting legacy designs.
