Procurement Notes
Verify the specific suffix against official Infineon documentation to confirm pinout and electrical characteristics. Ensure compatibility with PSoC Creator development tools. Check moisture sensitivity levels and reflow soldering profiles prior to assembly. Confirm RoHS compliance status through current datasheets.
Selection Notes
Select this model for designs requiring integrated analog peripherals alongside digital control. The 8051 architecture offers established code compatibility. Consider the SSOP package constraints for board space. Validate that the 16 kB memory size meets application requirements before finalizing the component choice.
Part Context
This component belongs to the CY8C32xx series of PSoC 3 microcontrollers. It combines a standard 8051 CPU with configurable analog and digital blocks. The series is designed for cost-effective solutions in consumer electronics and industrial control where mixed-signal capabilities are essential.
Replacement Considerations
Consult official Infineon substitution guides for verified equivalents. Cross-reference pinouts and memory sizes when considering alternative packages within the same family.
