Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix 'N' against the manufacturer's official documentation to confirm package type, temperature grade, and tape-and-reel specifications. Ensure compatibility with the required development tools, such as PSoC Designer, for firmware implementation. Cross-reference the datasheet revision *Y for any silicon errata relevant to this specific batch.

Application Specific Microcontrollers Selection Notes

Select this component when a design requires integrated capacitive sensing without external controllers. The 16 KB Flash and 2 KB SRAM accommodate moderate application complexity. Verify that the QFN-24 package pinout aligns with the PCB layout constraints. Consider the 1.71 V minimum supply voltage if designing for battery-operated applications.

Application Specific Microcontrollers Part Context

This part belongs to the CY8C20xx6A/S series of programmable system-on-chip controllers. These devices are designed to replace multiple traditional MCU components by integrating configurable analog and digital blocks. The series emphasizes ease of use through SmartSense technology, reducing manual tuning efforts during production.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the same family include CY8C20346A-24LQXIT (higher I/O count) or CY8C20236A-24LQXIT (lower memory). Verify pin compatibility and memory size requirements before substitution. Other packages in the series offer different I/O counts but may require schematic redesign.
