USBN9604SLBX/NOPB

Controllers Overview

The USBN9604SLBX/NOPB is a Universal Serial Bus controller manufactured by Texas Instruments, originally under the National Semiconductor brand. It implements the USB 1.0 and 1.1 specifications for full-speed node control. The device operates within a supply voltage range of 3 V to 5.5 V, with a nominal rating of 5 V. It features an 8-bit external data bus and an 8-bit address bus, supporting a maximum functional clock frequency of 24 MHz. The component is housed in a 28-pin Quad Flat Package (QCC28) or CSP-28 configuration. It functions as a single-function interface controller designed for embedded applications requiring standard USB connectivity.

Controllers Feature Summary

• Supports USB 1.0 and 1.1 protocol standards for full-speed data transfer
• Integrates parallel-to-serial conversion capabilities for host and peripheral modes
• Includes built-in power management features for suspend and resume operations

Controllers Applications

• USB peripheral devices requiring full-speed compliance
• Embedded systems integrating USB connectivity
• Industrial controllers utilizing standard USB interfaces

Controllers Procurement Notes

Verify the specific suffix 'SLBX' against official Texas Instruments documentation to confirm package type and pinout compatibility. Confirm RoHS status and lead-free plating requirements if applicable to the target assembly process. Check current product lifecycle status as older National Semiconductor designs may be discontinued or subject to last-time buy restrictions.

Controllers Selection Notes

Select this component when designing systems strictly adhering to USB 1.0 or 1.1 protocols rather than USB 2.0 high-speed requirements. Ensure the design accommodates the 28-pin QCC/CSP package constraints and the 3V to 5.5V operating voltage range. Verify that the host system provides the necessary 24 MHz clock signal required for proper controller operation.

Controllers Part Context

This part belongs to the USBN96 series of USB controllers produced by National Semiconductor, which was acquired by Texas Instruments. The USBN9604 variant specifically targets full-speed node applications. The 'NOPB' suffix indicates a non-lead-based (lead-free) packaging option compliant with environmental directives.
