Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the exact operating voltage limits and pinout compatibility with the target PCB layout. Ensure the component meets RoHS compliance requirements for the intended market. Cross-reference the datasheet revision to confirm peripheral availability.

Selection Notes

Select this model for designs requiring moderate processing speed with integrated analog capabilities. The PSoC architecture allows flexible routing of peripherals to GPIOs. Consider the limited I/O count compared to larger packages if extensive external connections are needed. Evaluate power consumption profiles against the specific application duty cycle.

Part Context

This component belongs to the PSoC 4200 family, designed for cost-sensitive and low-power applications. It combines a standard ARM processor with configurable analog blocks. The series targets consumer electronics and industrial control where small form factors and mixed-signal integration are prioritized over high-performance computing.
