Description The AU9254A21 is an integrated single chip USB hub controller designed for the emerging industry-standard Universal Serial Bus (USB). The AU9254A21 supports four USB downstream ports. Each downstream port has power switch control, and over-current sensing. Single chip integration makes the AU9254A21 the most cost effective stand-alone USB hub solution available in the market. Downstream ports can be used to connect various USB peripheral devices, such as USB printers, modems, scanners, cameras, mice, or joysticks to the system without adding external glue logic. 1.2. Features • • • • • • • Fully compliant with the Universal Serial Bus Specification, version 1.1. USB hub design is compliant with Universal Serial Bus Hub Specification, revision 1.1. Single chip integrated USB hub controller with embedded proprietary processor. Supports four bus-powered/self-powered downstream ports. Built-in 3.3v voltage regulator allows single +5V operating voltage, resulting in reduced overall system cost. Runs at 12Mhz frequency. 28-pin SSOP package, both normal size (body size 209 mil) and smaller size (body size 150 mil) are available. INTRODUCTION 1 This Page Intentionally Left Blank INTRODUCTION 2 2.0 Application Block Diagram The AU9254A21 is a single chip 4-port USB hub controller. The upstream port is connected to the USB system. The downstream ports can be used for a mouse, joystick, scanner, printer or other device.

Latch-Up Test Results Test Description: Latch-Up testing was performed at room ambient using an IMCS-4600 system which applies a stepped voltage to one pin per device with all other pins open except Vdd and Vss which were biased to 5Volts and ground respectively. Testing was started at 5.0V (Positive) or 0V (Negative), and the DUT was biased for 0.5 seconds. If neither the PUT current supply nor the device current supply reached the predefined limit (DUT=00mA, Icc=100mA), then the voltage was increased by 0.1Volts and the pin was tested again. This procedure was recommended by the JEDEC JC-40.2 CMOS Logic standardization committee. Notes: 1. DUT: The device under test. 2. PUT: The pin under test.
