DESCRIPTION

GL850G is Genesys Logic’s advanced STT hub solutions which fully comply with Universal Serial Bus Specification Revision 2.0. GL850G 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 worldwide.

GL850G provides multiple advantages to simplify board level design that help achieving lowest BOM (Bill of Material) for system integrator. GL850G integrates both 5V to 3.3V and 3.3V to 1.8V low dropout voltage regulator into single chip, therefore no external LDO required.

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 provides better design flexibility for customers. The complicated settings such as PID, VID, and number of downstream ports settings…etc. are easily achieved by programming the external EEPROM or SMBUS mode.

GL850G is a full function solution which supports both Individual and Gang (4 ports as a group) mode for power management (Individual mode is only available in QFN28 package). Number of downstream ports and non/removable downstream port can be configured by different ways, such as EEPROM, SMBUS or I/O strapping. For the detailed configuration methods, please refer to the following table.
