Microcontrollers Procurement Notes

Verify the specific suffix S443 against official Infineon documentation to confirm package type and moisture sensitivity level. Ensure compatibility with required operating temperature ranges (-40 °C to 105 °C). Confirm RoHS compliance status via the latest datasheet revision. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Microcontrollers Selection Notes

Select this component when 256 kByte flash and 32 kByte SRAM are sufficient for application code and data storage. Choose over lower-density variants if advanced analog peripherals like op-amps and comparators are required. Consider the 48 MHz clock speed for processing latency requirements. Verify pin count availability matches the PCB layout constraints.

Microcontrollers Part Context

This part belongs to the PSoC™ 4100S Plus series, designed for cost-sensitive applications requiring high integration. It shares the Cortex-M0+ core with other PSoC 4 devices but offers enhanced analog performance compared to the base PSoC 4000S series. The family targets general-purpose MCU needs with programmable interconnects.

Microcontrollers Replacement Considerations
