Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix 'IT' against the manufacturer's current datasheet to confirm packaging details such as tape and reel specifications. Ensure compatibility with RoHS standards and check for any recent silicon errata or qualification status updates relevant to production integration.

Application Specific Microcontrollers Selection Notes

Select this component when 16 kB of Flash and 2 kB of SRAM are required alongside CapSense functionality. The 24-pin QFN package offers 16 sensing inputs plus additional GPIOs. Consider the 1.71 V to 5.5 V operating range for flexible power supply designs and verify that the 24 MHz maximum clock speed meets processing requirements.

Application Specific Microcontrollers Part Context

This part belongs to the CY8C20xx7/S series of PSoC devices, which combine programmable analog and digital blocks with an MCU core. The 'S' variant typically denotes specific feature sets or package options within the broader CapSense controller lineup, designed to replace multiple traditional components in single-chip solutions.

Application Specific Microcontrollers Replacement Considerations

Check for direct pin-compatible substitutes within the CY8C20x37/47/67/S family, such as CY8C20347 without the 'S' suffix if features align. Verify memory sizes and package dimensions (24-QFN) to ensure mechanical fit. Consult the latest Infineon/Cypress documentation for any discontinued status or recommended new parts.
