GENESYS/创惟科技 GL854G-MSG10 LQFP7x7-64 USB 2.0 MTT 7端口集线器控制器

Features

● Multiple Chip Package (MCP) architecture

Integrates two standard USB 4-port hub silicon dies into single chip

Supports 7 USB 2.0 compliant downstream ports

● Multiple Transaction Translator (MTT)

Provides dedicated TT control logics for each downstream port

Superior performance when multiple FS devices operate concurrently

● Compliant with USB specification Revision 2.0

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

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

Backward compatible to USB specification Revision 1.1

Each downstream port supports status indicator, with automatic and manual modes

Conform to self power and bus power requirements

● Integrated USB transceiver

Compliant with USB electrical requirements

Ultralow power consumption

Improve output drivers with slew-rate control for EMI reduction

Internal power-fail detection for ESD recovery

● On-chip 8-bit micro-processor

Support customized PID, VID by reading external EEPROM

Support downstream port configuration by reading external EEPROM

● Smart power management features

Support individual / gang mode over-current detection for all downstream ports

Automatic switching between self-powered and bus-powered modes

● Lower BOM cost

Single external 12 MHz crystal / Oscillator clock input

On-chip 5V to 3.3V power regulator

Built-in upstream port 1.5KΩ pull-up and downstream port 15KΩ pull-down resistors

Support low-cost 24C02 EEPROM

● Features for hub compound applications

Support compound-device (non-removable in downstream ports) by I/O pin configuration

Provide 12MHz clock source for other USB device connected to the downstream ports

● GL854G-MSG10 Available package type: 64 pin LQFP package (7x7mm)
