Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding pinout and resource allocation. Confirm RoHS compliance status through current datasheet revisions before finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate I/O count and extensive analog programmability is required. The CY8C28243 offers a distinct resource profile compared to other CY8C28xxx variants, specifically lacking CapSense hardware but providing full analog block access. Evaluate the available digital and analog block counts against application needs to ensure optimal resource utilization without over-specifying.

Part Context

This part belongs to the CY8C28xxx subgroup of the PSoC 1 family, characterized by up to 12 regular analog blocks and 12 digital blocks. It shares architectural similarities with the CY8C28x43 and CY8C28x45 series but differs in specific resource availability such as CapSense support. The device integrates system resources like low voltage detection and power-on reset circuits.
