Procurement Notes

Verify the specific suffix 'Z' status if applicable, as it may indicate lead-free or end-of-life conditions. Confirm the exact package variant matches the design footprint. Check RoHS compliance documentation for regulatory requirements. Ensure the operating temperature range meets environmental specifications. Validate pin compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when a balance of processing speed and low power consumption is required. The 48 MHz Cortex-M0 core suits applications needing moderate computational throughput. The integrated CapSense and LCD drivers reduce bill of materials by eliminating external components. Consider the 28-pin SSOP package for space-constrained designs requiring surface mount assembly.

Part Context

This part belongs to the Infineon PSoC 4200 family, designed for cost-sensitive and power-efficient applications. The family utilizes the ARM Cortex-M0 processor core, offering a scalable platform for various embedded needs. The PSoC architecture allows for customizable analog and digital peripherals, providing flexibility in system design without requiring multiple discrete chips.

Replacement Considerations

Check for equivalent parts within the PSoC 4200S or PSoC 4200L families that offer similar pin counts and peripheral sets. Verify that any substitute maintains the same package dimensions and thermal characteristics. Ensure the replacement supports the required flash size and memory configuration.
