Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure compliance with RoHS directives and check for any end-of-life notifications regarding production status before finalizing procurement plans.

Application Specific Microcontrollers Selection Notes

Select this model when a design requires integrated capacitive sensing alongside standard digital peripherals. The 24 MHz clock speed suits moderate processing loads. Verify that the 1 kB RAM and 8 kB Flash meet firmware size constraints. Consider the QFN-32 footprint for PCB layout compatibility and thermal management requirements in the target enclosure.

Application Specific Microcontrollers Part Context

This component belongs to the CY8C20xx6A series of PSoC 1 mixed-signal arrays. It shares architectural similarities with other members like the CY8C20346A but offers distinct memory and pin configurations. The part utilizes the Cypress Semiconductor legacy branding now under Infineon Technologies.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes include CY8C20346A-24LQXI and CY8C20446A-24LQXI. These alternatives share the same package and core architecture but differ in memory capacity and peripheral availability. Validate pinout compatibility and software register mappings before implementing any cross-model replacement.
