• M8C CPU operating at up to 24 MHz with Harvard architecture
• Up to 34 GPIOs with high sink current capability (25 mA per pin)
• Integrated I2C Slave and SPI Master/Slave modules

Application Specific Microcontrollers Applications

• Capacitive touch button interfaces
• Slider and proximity sensor applications
• Low-power embedded control systems

Application Specific Microcontrollers Procurement Notes

Verify the specific memory configuration (Flash/SRAM size) required for the design, as the CY8C20xx7/S family offers variants with 8 KB, 16 KB, or 32 KB Flash. Confirm that the 48-pin QFN package dimensions align with the PCB footprint. Ensure development tools like PSoC Designer are available for configuration.

Application Specific Microcontrollers Selection Notes

Select this component when a combination of programmable analog/digital resources and dedicated CapSense functionality is needed. The 'S' suffix indicates support for SmartSense auto-tuning. Compare against other CY8C20xx7 variants if different pin counts or memory sizes better suit the application constraints.

Application Specific Microcontrollers Part Context

This part belongs to the CY8C20xx7/S series of 1.8 V CapSense Controllers. It shares architectural similarities with other members of the family but is distinguished by its specific package type and memory configuration options available within the 48-pin QFN form factor.

Application Specific Microcontrollers Replacement Considerations

Check for updated revisions within the CY8C20467S series. Verify compatibility with existing firmware due to potential silicon errata or minor electrical specification changes between manufacturing lots.
