Procurement Notes

Verify the exact part number against official Infineon documentation, as the provided model contains a potential typo. Confirm availability status through authorized distributors, as this component may be subject to lifecycle changes. Ensure compliance with RoHS directives and check moisture sensitivity levels for proper handling during assembly.

Selection Notes

Select this component when an 8-bit architecture with integrated analog capabilities is required. Consider the 16 kB Flash size and 256 B RAM limits for application complexity. Evaluate the 48-pin SSOP package constraints against board space requirements. Compare against other PSoC 1 variants if different pin counts or memory sizes are needed.

Part Context

This microcontroller belongs to the Infineon PSoC 1 series, which combines an 8-bit CPU with programmable analog and digital blocks. The CY8C27xxx series specifically targets applications needing mixed-signal integration in a small form factor. It represents a solution for reducing component count by integrating peripheral functions onto a single chip.

Replacement Considerations

Check for direct substitutes within the CY8C27xxx series with identical memory and pin configurations. Verify compatibility with existing firmware due to potential minor architectural differences between revisions. Consult Infineon's obsolescence notices for long-term supply assurance.
