Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'LKXI' against the manufacturer's ordering guide to confirm the exact package type (24-pin QFN) and temperature grade. Ensure compatibility with the required flash size variant within the CY8C20xx7/S family.

Application Specific Microcontrollers Selection Notes

Select this model if the design requires 16 KB of program memory and a 24-pin footprint. Confirm that the 24 MHz clock speed meets timing requirements. Verify that the GPIO count (up to 34 total) satisfies the pinout constraints for the specific application.

Application Specific Microcontrollers Part Context

This component belongs to the CY8C20xx7/S series, which are 1.8 V CapSense controllers. The '24' in the part number indicates the 24 MHz maximum frequency and typically corresponds to the 24-pin QFN package variant offering 16 sensing inputs or more depending on configuration.

Application Specific Microcontrollers Replacement Considerations

Check for other variants in the CY8C20xx7/S family with different memory sizes (8 KB or 32 KB) or package options (16-pin, 32-pin, 48-pin) if pin count or memory requirements differ. Ensure the replacement maintains the same operating voltage and temperature range.
