Procurement Notes
Verify the specific ordering suffix against the official Infineon datasheet to confirm package type and temperature range. Ensure compatibility with PSoC Designer software versions for development. Confirm RoHS compliance status through manufacturer documentation before procurement.
Selection Notes
Select this component when design requirements include both analog signal processing and digital control within a single chip. The CY8C28xxx series provides varied resource options; verify that the specific subgroup meets the necessary digital block count and analog channel requirements for the application.
Part Context
This part belongs to the CY8C28xxx PSoC 1 family, which combines an 8-bit microcontroller with programmable analog and digital blocks. The family allows designers to minimize board size and component count by integrating multiple functions into one silicon solution.
Replacement Considerations
Check the official datasheet for cross-reference information. Verify pinout compatibility and resource availability if substituting with other CY8C28xxx variants or legacy Cypress parts.
