Procurement Notes

Verify the specific package suffix 'PVXI' against the manufacturer's current ordering guide to ensure correct pinout and thermal specifications. Confirm that the component is sourced from authorized Infineon or Cypress distributors to guarantee authenticity. Check for any recent lifecycle status changes or obsolescence notices associated with this specific part number variant before finalizing procurement plans.

Selection Notes

Select this component when a design requires a high density of configurable analog and digital blocks on a single chip. It is suitable for applications needing precise analog signal conditioning alongside robust digital control logic. Consider the 24 MHz processing speed and available memory sizes relative to application complexity. Ensure the required I/O count and analog channel availability fit within the 28-pin SSOP package constraints.

Part Context

This device belongs to the CY8C29x66 family of PSoC 1 Programmable System-on-Chip devices. These parts are designed to replace multiple traditional MCU-based components by integrating configurable analog and digital peripherals. The family shares common architectural features but varies in resource counts and package options to suit different application scales.

Replacement Considerations

Consult the official datasheet for cross-reference information. Verify compatibility with existing firmware due to potential differences in register mappings or peripheral configurations between legacy Cypress and current Infineon revisions.
