Please refer to GL852 datasheet for more detailed information. Genesys Logic also provides GL852 for multiple TT hub solution to target on systems which require higher performance for full/low-speed devices, like docking station, embedded system … etc. To fully meet the cost/performance requirement, GL850G is a single TT hub solution for the cost requirement. Number of downstream ports setting can be configured by IO setting in absence of EEPROM. Please refer the table in the end of this chapter for more detail.
GENESYS LOGIC USB HUB DRIVER FULL
The GL850G is a full function solution which supports both Individual/Gang power management modes and the two-color (green/amber) status LEDs. GL850G also support both Individual and Gang modes (4 ports as a group) for power management. to Chapter 5).Įach downstream port of GL850G supports two-color (green/amber) status LEDs to indicate normal/abnormal status. The more complicated settings such as PID, VID, and number of downstream ports settings are easily achieved by programming the external EEPROM (Ref. GL850G is designed for customers with much flexibility. Default settings in the internal mask ROM is responded to the host without having external EEPROM. Firmware of GL850G 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.
GL850G embeds an 8-bit RISC processor to manipulate the control/status registers and respond to the requests from USB host. Also, GL850G’s power enable pin supports both high-enable and low-enable power switch that provides better flexibility on component selection. GL850G integrated both 5V to 3.3V and 3.3V to 1.8V voltage drop regulator into single chip, therefore no external LDO required. GL850G provides multiple advantages to simplify board level design that help achieve lowest BOM (bill of material) for system integrator. GL850G has proven compatibility, lower power consumption figure and better cost structure above all USB2.0 hub solutions worldwide.
