Controllers Procurement Notes

Verify the specific suffix NU-02 against official Microchip documentation to confirm pinout compatibility and electrical specifications. Ensure that the source document explicitly identifies this part number as distinct from similar variants within the USB2230 family. Cross-reference the manufacturer designation to confirm Microchip Technology as the sole authorized producer.

Controllers Selection Notes

Select this component when system design requires combined USB flash media control and IrDA functionality within a single integrated circuit. Evaluate the 128-pin TQFP package constraints against available PCB real estate. Confirm that the integrated power FETs meet the voltage and current requirements of the target memory cards without external components.

Controllers Part Context

This controller belongs to the fifth generation of USB flash media controllers produced by SMSC, which was subsequently acquired by Microchip Technology. The series represents a transition period where legacy SMSC designs were maintained under the Microchip portfolio. The USB2230 variant specifically targets applications needing both high-speed data transfer and infrared connectivity.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified sources. Designers should consult Microchip Technology directly for current equivalent recommendations or updated family members that may have replaced this specific revision.
