Application Specific Microcontrollers Procurement Notes

Verify the specific suffix '24LQXI' against official Cypress/Infineon documentation to confirm package type (24-QFN) and operating temperature range (-40°C to 85°C). Ensure compatibility with design requirements for the M8C architecture and CapSense peripheral integration before procurement.

Application Specific Microcontrollers Selection Notes

Select this part when a dedicated CapSense controller with an integrated MCU is required. Compare pin counts and memory sizes against other CY8C20xx7 variants if fewer I/Os or different memory configurations are needed. Verify that the 24-pin QFN package fits the PCB layout constraints.

Application Specific Microcontrollers Part Context

This component belongs to the CY8C20xx7/S family of PSoC Mixed Signal Arrays. These devices combine analog and digital peripherals with an 8-bit microcontroller core, specifically optimized for low-power capacitive sensing solutions.

Application Specific Microcontrollers Replacement Considerations

Check for updated Infineon part numbers within the CY8C20xx7 series. Verify functional equivalence regarding CapSense channel count and memory size if substituting with similar models like the CY8C20337.
