Procurement Notes

Verify that the component is sourced from authorized distributors or directly from Infineon/Cypress to ensure authenticity. Confirm the specific ordering suffix matches the required package type and temperature grade. Check for any obsolescence notices or lifecycle status updates from the manufacturer before finalizing procurement plans.

Selection Notes

Select this model when an automotive-rated mixed-signal controller with configurable analog peripherals is required. Ensure the design utilizes the full feature set available in the CY8C28x45 subgroup. Verify that the 28-pin SSOP package dimensions fit the PCB layout constraints and that the 3.0 V to 5.25 V supply range aligns with the system power architecture.

Part Context

This component belongs to the CY8C28xxx family of Programmable System-on-Chips (PSoC). Originally developed by Cypress Semiconductor, these devices are now managed under Infineon Technologies' portfolio. The CY8C284xx subgroup represents a specific resource configuration within this broader family, offering a complete set of analog and digital blocks for complex mixed-signal designs.

Replacement Considerations

Consult official Infineon documentation for qualified substitute part numbers within the CY8C28xxx series. Verify compatibility regarding pinout, memory size, and peripheral availability before replacing the component. Ordering suffixes may indicate variations in packaging or temperature ratings that must be matched.
