Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm the specific ordering suffix matches design requirements for package and temperature grade. Check current lifecycle status as discontinuation notifications may apply. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this model when a single-chip solution replaces multiple discrete MCU and analog components. Evaluate the available GPIO count against interface needs. Consider the analog block configuration for required ADC/DAC resolution. Verify that the M8C instruction set and memory size meet firmware complexity constraints.

Part Context

This part belongs to the CY8C24x94 series within the PSoC 1 Programmable System-on-Chip portfolio. It shares architectural similarities with variants like the CY8C24994-24BVXI but differs in packaging and commercial/industrial temperature ratings. The series emphasizes design flexibility through its programmable interconnect and user-configurable logic blocks.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult official obsolescence notices or contact technical support for validated replacement strategies.
