GL850G provides tested compatibility, lower energy consumption amount and better cost structure above all USB2.0 center solutions world-wide.GL850G provides multiple benefits to make easier board level style that assist achieve most affordable BOM (bill of materials) for system integrator.GL850G included both 5V to 3.3V and 3.3V to 1.8V voltage drop regulator into single chip, thus no external LDO required.
Furthermore, GL850Gs strength enable pin facilitates both high-enabIe and low-enabIe power switch that provides better flexibility on element selection. GL850G embeds an 8-bit RISC processor to manipulate the controlstatus registers and react to the demands from USB host. Firmware of GL850G will control its general objective IO (GPIO) to access the exterior EEPROM and after that react to the host the customized PID and VID set up in the external EEPROM. Default settings in the inner mask ROM is reacted to the web host without getting external EEPROM. The more complicated settings like as PID, VID, and amount of downstream slots settings are usually easily achieved by encoding the external EEPROM (Ref. ![]() The GL850G is a complete function answer which supports both IndividualGang energy management settings and the twó-color (greenamber) position LEDs. Please pertain the desk in the end of this part for more detail. Amount of downstream ports setting up can become set up by IO establishing in absence of EEPROM. Ref. to Part 5) To fully satisfy the costperformance requirement, GL850G is definitely a one TT hub option for the cost requirement. Genesys Logic also offers GL852 for multiple TT hub remedy to target on systems which require higher efficiency for fulllow-speed products, like docking train station, embedded system etc. Please recommend to GL852 datasheet for even more detailed info. TT (deal translator) is usually the main traffic control engine in an USB 2.0 centre to deal with the unbalanced visitors swiftness between the upstream port and the downstream ports.
