Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature rating. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents before procurement.

Application Specific Microcontrollers Selection Notes

Select this component when a compact 16-pin footprint is required alongside programmable analog capabilities. Ensure the design utilizes the available GPIO pins effectively, as the device offers limited I/O compared to higher-pin-count variants in the same series.

Application Specific Microcontrollers Part Context

This part belongs to the PSoC 1 CY8C20xx7/S series, which integrates programmable analog and digital blocks on a single chip. The CY8C20055 variant specifically provides 16 KB of Flash memory, distinguishing it from lower-capacity models like the CY8C20034 within the same family.

Application Specific Microcontrollers Replacement Considerations

Check for direct pin-compatible substitutes within the CY8C20xx7 series that offer equivalent memory sizes. Verify if alternative packages (e.g., SOIC) are available if surface-mount constraints change.
