Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the required pinout configuration for the 16-pin SOIC variant. Check for any silicon errata or recommended workarounds relevant to the production batch before finalizing procurement specifications.

Application Specific Microcontrollers Selection Notes

Select this model when a solution requiring integrated capacitive sensing without external components is needed. The 16-pin SOIC package limits sensing inputs to 10 pins; verify that this count meets application requirements. Consider the 1.71 V minimum operating voltage for low-power battery applications and ensure the 24 MHz clock speed aligns with processing demands.

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 like the CY8C20237 but differs in memory size and specific feature sets. The series is designed to replace multiple traditional MCU-based system components with a single programmable chip.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the same package and pinout include other variants from the CY8C20x37/47/67/S family, such as the CY8C20237-24SXI, provided memory and I/O requirements are met. Verify electrical specifications and firmware compatibility when cross-referencing with similar devices.
