Procurement Notes

Verify the specific suffix '483' against official Infineon documentation to confirm pinout and electrical characteristics match project requirements. Confirm RoHS compliance status through current datasheets. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference lead markings with manufacturer standards for authenticity.

Selection Notes

Select this model when a compact UFQFN-40 footprint is required alongside moderate I/O counts. It is appropriate for designs needing 48 MHz processing speed with integrated analog peripherals. Consider alternative packages if higher pin counts or different thermal performance are necessary. Evaluate power consumption profiles against specific application duty cycles.

Part Context

This component belongs to the PSoC 4 family, which combines a standard MCU core with configurable analog and digital hardware resources. The LQI variant specifically denotes the UFQFN-40 package option within the CY8C4245 line. This series targets cost-sensitive embedded applications requiring flexibility in peripheral integration without external components.

Replacement Considerations

Check for CY8C4245AXQ-483 for TQFP-44 packaging compatibility. Verify CY8C4245PVI-482 for SSOP-28 alternatives. Ensure functional equivalence regarding memory size and clock speed before substitution.
