Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly. Check current lifecycle status as the part may be discontinued. Ensure packaging specifications match design requirements for surface-mount installation.

Application Specific Microcontrollers Selection Notes

Select this component when a low-pin-count MCU with integrated CapSense functionality is required. Verify that the 16-UFQFN package fits the PCB layout constraints. Ensure the 16 kB program memory and 2 KB RAM meet application storage needs. Confirm compatibility with 1.71 V to 5.5 V power rails.

Application Specific Microcontrollers Part Context

This part belongs to the Cypress PSoC 1 family, specifically the CY8C20xx6A series. It combines digital and analog resources on a single CMOS chip. The 'A' suffix typically denotes an enhanced version of the base CY8C20246 model. The 'LKXI' suffix indicates the 16-UFQFN package and temperature grade.

Application Specific Microcontrollers Replacement Considerations

Check for direct pin-to-pin replacements within the CY8C20246A series. Consider newer Infineon PSoC 4 or PSoC 6 devices for upgraded performance. Verify software compatibility if migrating to different core architectures like ARM Cortex-M.
