GL850G is Genesys Logic’s advanced version Hub solutions which fully comply with Universal Serial Bus Specification Revision 2.0. GL850 inherits Genesys Logic’s cutting edge technology on cost and power efficient serial interface design. GL850G has proven compatibility, lower power consumption figure and better cost structure above all USB2.0 hub solutions. GL850G provide multiple advantages to simplify board level design that help achieve lowest BOM (bill of material) for system integrator. GL850G integrated both 5V to 3.3V and 3.3V to 1.8V voltage drop regulator into single chip, therefore no external LDO required. Also, GL850G’s power enable pin supports both high-enable and low-enable power switch that provides better flexibility on component selection. GL850G embeds an 8-bit RISC processor to manipulate the control/status registers and respond to the requests from USB host. 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. Default settings in the internal mask ROM is responded to the host without having external EEPROM. GL850G 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.
