Product Summary

The GL850 is a Low Power HUB Controller which fully complies with Universal Serial Bus Specification Revision 2.0. GL850 embeds an 8-bit RISC processor to manipulate the control/status registers and respond to the requests from USB host. Firmware of the GL850 will control its general purpose I/O (GPIO) to access the external EEPROM and then respond to the host the customized PID and VID configured in the external EEPROM. Default settings in the internal mask ROM is responded to the host without having external EEROM. The GL850 is designed for customers with much flexibility. The more complicated settings such as PID, VID, and number of downstream ports settings are easily achieved by programming the external EEPROM (Ref. to Chapter 5).

Parametrics

GL850 absolute maximum ratings: (1)VCC Power Supply: －0.5 to +3.6 V; (2)VIN Input Voltage for digital I/O(EE_DO)pins: －0.5 to +3.6 V; (3)VIN Input Voltage for digital I/O(Ovcur1－4,Pself,Reset)pins: －0.5 to +5.25 V; (4)VINUSB Input Voltage for USB signal (DP, DM)pins: －0.5 to +3.6 V; (5)TS Storage Temperature under bias: －60 to +100 ℃.

Features

GL850 features: (1)Each downstream port supports two－color status indicator, with automatic and manual modes compliant to USB specification Revision 2.0; (2)Support both individual and gang modes of power management and over－current detection for downstream ports (64－pin LQFP); (3)Support gang mode of power management and over－current detection for downstream ports; (4)Conform to bus power requirements; (5)Automatic switching between self－powered and bus－powered modes; (6)Integrate USB 2.0 transceiver; (7)PLL embedded with external 12 MHz crystal; (8)Operate on 3.3 Volts; (9)Embed serial resister for USB signals and integrate pull－up resister for upstream USB signal; (10)Improve output drivers with slew－rate control for EMI reduction; (11)Internal power－fail detection for ESD recovery; (12)64/48－pin LQFP package.
