Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'I' versus 'IT' for tape-and-reel packaging requirements. Confirm RoHS compliance status through official datasheets. Check for end-of-life notifications or discontinuance alerts prior to procurement decisions.

Application Specific Microcontrollers Selection Notes

Select this component when 16 KB of code space and 2 KB of RAM are sufficient for the application logic. Ensure the design utilizes the QFN-24 footprint constraints. Verify that the required number of GPIOs fits within the 17-pin limit including CapSense channels.

Application Specific Microcontrollers Part Context

This part belongs to the CY8C20xx6A series of PSoC1 devices. It shares architectural similarities with other members like the CY8C20346A-24LQXIT, differing primarily in packaging quantities or minor revision identifiers. It serves as a bridge between standard 8-bit MCUs and more complex mixed-signal solutions.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes include the CY8C20346A-24LQXIT for identical functionality in reel packaging. Cross-reference with CY8C20436A-24LQXI if additional I/O count is acceptable.
