Procurement Notes

Verify the specific suffix LFXI against official Infineon documentation to confirm package type and temperature grade. Confirm availability status as distribution listings may vary. Ensure compatibility with PSoC Designer software versions for development. Check for any end-of-life notifications or obsolescence warnings prior to procurement.

Selection Notes

Select this component when a high pin count MCU with integrated touch sensing is required. Compare memory sizes and I/O counts against alternatives like the CY8C24x94 series if different packaging is needed. Verify that the 3V to 5.25V operating range matches the system power design constraints.

Part Context

This part belongs to the PSoC 1 architecture, which combines a processor with configurable analog and digital peripherals. It is designed for low-power, cost-sensitive applications requiring mixed-signal capabilities. The family emphasizes ease of use through graphical configuration tools.

Replacement Considerations

Check for direct substitutes within the CY8C24x94 family with compatible pinouts. Verify functional equivalence regarding CapSense channel counts and ADC resolution before substitution.
