CHAPTER 1 GENERAL DESCRIPTION
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.
*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.
