USBN9604-28MX/NOPB

Controllers Overview

The USBN9604-28MX/NOPB is a Universal Serial Bus Full Speed Node Controller compatible with USB Specification versions 1.0 and 1.1. It integrates a high-speed transceiver, a 3.3V regulator, a Serial Interface Engine (SIE), endpoint FIFOs, an 8-bit parallel interface, and a clock generator. The device supports seven endpoint pipes: one bidirectional control endpoint with an 8-byte FIFO and six unidirectional endpoints with 64-byte FIFOs each. It operates on a 24 MHz oscillator with internal 48 MHz clock generation and features enhanced DMA support for automatic data handling.

Controllers Feature Summary

• Integrates a full-speed USB node controller with an embedded transceiver and 3.3V regulator
• Supports seven endpoint pipes including one control endpoint and six unidirectional endpoints
• Features an advanced Automatic DMA mechanism for CPU-independent bulk or isochronous transfers
• Provides versatile microcontroller interfacing via selectable 8-bit parallel or MICROWIRE modes

Controllers Applications

• USB peripheral devices requiring full-speed connectivity
• Portable applications utilizing bus-powered operation
• Systems needing direct memory access for high-throughput data transfer

Controllers Procurement Notes

Verify the package type matches the specific suffix requirements, as the -28M designation indicates a standard SOIC package distinct from other variants in the family. Confirm that the NOPB suffix aligns with lead-free manufacturing specifications required by the target assembly process. Ensure the source documentation explicitly lists this part number to avoid confusion with similar controllers.

Controllers Selection Notes

Select this component when a USB 1.0/1.1 compliant node controller with integrated transceiver functionality is required. It is suitable for designs needing an 8-bit parallel interface or MICROWIRE serial connection to a host processor. Consider the enhanced DMA capabilities if large block data transfers are necessary without constant CPU intervention.

Controllers Part Context

This device belongs to the USBN9603/USBN9604 family of Universal Serial Bus Full Speed Node Controllers. It serves as an advanced version of the USBN9602, offering improved DMA support and integrated voltage regulation. The USBN9604 variant specifically refers to the standard package configuration compatible with existing designs using the predecessor model.

Controllers Replacement Considerations

The USBN9604-28M is pin-to-pin compatible with the USBN9602-28M. Designers upgrading from older hardware should verify register compatibility and ensure that the enhanced DMA features do not require firmware adjustments.
