GL852 is Genesys Logic’s brand new Hub solutions which fully comply with Universal Serial Bus Specification Revision 2.0. This series includes GL852.GL852 embeds an 8-bit RISC processor to manipulate the control/status registers and respond to the requests from USB host. Firmware of GL852 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. GL852 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 GL852 supports two-color (green/amber) status LEDs to indicate normal/abnormal status.To fully meet the performance requirement, GL852 series is a multiple TT hub solution to provide every down stream port with a TT. With the dedicated TT in each down stream port, GL852 can provide the best performance even connect with several Full/Low-Speed devices and running heavy bandwidth-consuming operations concurrently.
