Description

GL850A is Genesys Logic's advanced version Hub solutions which fully comply with Universal Serial Bus Specification Revision 2.0. GL850A embeds an 8-bit RISC processor to manipulate the control/status registers and respond to the requests from USB host. Firmware of GL850A 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. GL850A 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). Each downstream port of GL850A supports two-color (green/amber) status LEDs to indicate normal/abnormal status. GL850A also support both Individual and Gang modes (4 ports as a group) for power management. The GL850A (64-pin) is a full function solution which supports both Individual/Gang power management modes and the two-color (green/amber) status LEDs. The low pin-count version GL850A (48-pin) only supports Gang mode. Please refer the table in the end of this chapter for more detail. To fully meet the cost/performance requirement, GL850A is a single TT hub solution for the cost requirement. 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. *TT (transaction translator) is the main traffic control engine in an USB 2.0 hub to handle the unbalanced traffic speed between the upstream port and the downstream ports.
