Controllers Procurement Notes

Verify the specific suffix MX against the manufacturer's official documentation to confirm the SOIC-28 package configuration. Ensure that the NOPB designation aligns with current RoHS compliance requirements before finalizing procurement orders. Cross-reference the part number with the latest datasheet revision to confirm functional equivalence and availability status.

Controllers Selection Notes

Select this component when designing USB 1.0 or 1.1 compliant full-speed nodes. It is suitable for applications requiring integrated transceivers and multiple endpoint FIFOs. Consider the available interface modes, such as the 8-bit parallel bus or MICROWIRE, based on the host controller's connectivity options. Evaluate the power consumption characteristics relative to system battery life requirements.

Controllers Part Context

This device belongs to the USBN960x family of USB node controllers manufactured by Texas Instruments, formerly National Semiconductor. It serves as an advanced version of the USBN9602, offering improved DMA support and flexible interface options. The series is designed to simplify USB implementation in embedded systems by integrating critical physical layer functions into a single IC.

Controllers Replacement Considerations

The USBN9604-28M/NOPB is a pin-to-pin compatible alternative within the same family. Verify functional differences regarding specific endpoint configurations or interface modes before substitution. Consult the manufacturer's compatibility matrix to ensure equivalent performance in the target application.
