HS88458规格书详情

描述 Description

• Compliant to USB specification Revision 2.0

- Support 4/3/2 downstream ports by 1/0 pin configuration

USB 2.0 HUB Controller

- Upstream port supports both high-speed (HS) and full-speed (FS) traffic

- Downstream ports support HS, FS, and low-speed (LS) traffic

• On-chip 8-bit micro-processor

- RISC-like architecture

- USB optimized instruction set

• Single Transaction Translator {STT)

- Single TT shares the same TT control logics for all downstream port devices. This is the most cost

effective solution for TT. Multiple TT provides individual TT control logics for each downstream port.

This is a performance better choice for USB 2.0 hub

• Integrate USB 2.0 transceiver

• Each downstream port supports two-color status indicator, with automatic and manual modes compliant to

USB specification Revision 2.0

• Embed serial resister for USB signals

• Support both individual and gang modes of power management and over-current detection for

downstream ports

• Conform to bus power requirements

• Automatic switching between self-powered and bus-powered modes

• Support compound-device (non-removable in downstream ports) by 1/0 pin configuration

• Configurable non-removable device support

• Embeds 5V to 3.3V regulator

• Improve output drivers with slew-rate control for EMI reduction

• Internal power-fail detection for ESD recovery

• Applications:

— Stand-alone USB hub

— PC motherboard USB hub, Docking of notebook

— LCD monitor hub

- Any compound device to support USB HUB function
