Procurement Notes

Verify the specific ordering suffix 'SXI' corresponds to the SOIC tube package variant when sourcing components. Confirm that the required documentation matches the Infineon datasheet document number 38-12013 Rev. AD. Ensure compatibility with the PSoC Designer development environment for configuration and code generation. Check for any specific handling requirements related to moisture sensitivity levels indicated in the packaging information.

Selection Notes

Select this component when a design requires a high degree of hardware configurability within a single chip. It is suitable for applications needing precise analog signal conditioning combined with robust digital control logic. Consider this part if the design benefits from reducing component count by integrating multiple standard peripherals into programmable blocks. Evaluate the available Flash and SRAM sizes against application memory requirements before finalizing the selection.

Part Context

This device belongs to the CY8C29x66 series of PSoC Programmable System-on-Chip devices. These controllers are designed to replace multiple traditional MCU-based system components with one low-cost single-chip solution. The series emphasizes design flexibility and ease of use, targeting consumer, computation, communications, automotive, and industrial equipment markets through its configurable mixed-signal array architecture.

Replacement Considerations

Consult official replacement lists or cross-reference tools provided by Infineon for verified substitute part numbers. Ensure any alternative maintains compatible pinout, memory size, and peripheral configurations. Verify that the replacement supports the same operating voltage and temperature ranges required by the original design specifications.
