Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus channels. Designers must confirm lead times and authenticity through verified supply chain partners due to the discontinued status.

Selection Notes

Select this part for applications requiring integrated USB connectivity and high configurability in an 8-bit MCU. Consider the EOL status when planning long-term production. Evaluate alternative PSoC 1 variants or newer generations if future supply stability is critical. Ensure design tools support the legacy M8C architecture.

Part Context

Part of the CY8C24x94 series within the PSoC 1 family, designed to replace multiple discrete components. It combines a CPU, memory, and programmable analog/digital peripherals on a single chip. This integration reduces board space and component count compared to traditional MCU solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers should consult official replacement guides or contact technical support for qualified alternatives.
