Procurement Notes

Verify the specific suffix 'LTXI' against official Infineon documentation to confirm the QFN-32 tape-and-reel packaging configuration. Ensure compatibility with the required operating voltage and temperature ranges for your specific application environment before finalizing procurement decisions.

Selection Notes

Select this component when a mixed-signal SoC with integrated analog peripherals and an 8-bit processor is required. Consider the 24 MHz maximum clock speed and 16 kB memory capacity relative to processing needs. Verify that the QFN-32 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the PSoC 1 CY8C27xxx series, designed as a complete system-level solution. It targets markets requiring minimized board size and chip count by integrating configurable analog and digital blocks with a standard microcontroller core on a single chip.

Replacement Considerations

Consult official Infineon cross-reference guides for verified substitutes. Generic equivalents may lack the specific PSoC configurability or pinout compatibility required for direct replacement.
