GENESYS/创惟科技 GL850S SSOP-28 USB 2.0 4端口集线器控制器

GL850S FEATURES

● Compliant to USB specification Revision 2.0
● 4 downstream ports
● Upstream port supports both high-speed (HS) and full-speed (FS) traffic
● Downstream ports support HS, FS, and low-speed (LS) traffic
● 1 control pipe (endpoint 0, 64-byte data payload) and 1 interrupt pipe (endpoint 1, 1-byte data payload)
● Backward compatible to USB specification Revision 1.1
● On-chip 8-bit micro-processor
● RISC-like architecture
● USB optimized instruction set
● Dual cycle instruction execution
● Performance: 6 MIPS @ 12MHz
● With 64-byte RAM and 2K internal ROM
● Support customized PID, VID by reading external EEPROM
● Support downstream port configuration by reading external EEPROM
● Single Transaction Translator (TT) architecture
● Single TT shares the same TT control logics for all downstream port devices. This is the most cost effective solution for TT
● Each downstream port supports two-color status indicator, with automatic and manual modes compliant to USB specification Revision 2.0
● Support both individual and gang modes of power management and over-current detection for downstream ports
● Conform to bus power requirements
● Automatic switching between self-powered and bus-powered modes
● Integrated USB2.0 transceiver
● 0.35um CMOS technology
● PLL embedded with external 12 MHz crystal
● Operate on 3.3 Volts
● Improved output drivers with slew-rate control for EMI reduction
● Internal power-fail detection for ESD recovery
● 64-pin LQFP package

GL850S Applications
● Stand-alone USB hub
● PC motherboard USB hub, Ducking of notebook
● Any compound device to support USB HUB function
