GL850G-37是Genesys Logic先进的STT集线器解决方案,完全符合通用串行总线
规格修订2.0。 GL850G-37继承了Genesys Logic在成本和功耗方面的技术
高效的串行接口设计。 GL850G-37已被证明兼容,功耗更低,
优于全球所有USB2.0集线器解决方案的成本结构。
GL850G-37具有多种优势,可简化电路板级设计,帮助实现BOM(Bill
材料)用于系统集成商。 GL850G-37集成了5V至3.3V和3.3V至1.8V低压差
电压调节器集成到单芯片中,因此无需外部LDO。
GL850G-37嵌入一个8位RISC处理器来操纵控制/状态寄存器并响应
来自USB主机的请求。 GL850G-37的固件将控制其通用I / O(GPIO)来访问
外部EEPROM,然后响应主机在外部配置的定制PID和VID
EEPROM。内部掩膜ROM中的默认设置会响应主机而不需要外部
EEPROM。 GL850G-37为客户提供更好的设计灵活性。复杂的设置,如PID,
VID和下行端口设置数量等。通过对外部编程很容易实现
EEPROM,供应商命令或SMBUS模式(参考第5章)。
GL850G-37是一款全功能的解决方案,可支持Individual和Gang(4个端口作为一组)模式
电源管理(独立模式仅适用于QFN28封装)。下行端口号和
非可移动下游端口可以通过I / O捆扎,SMBUS或供应商命令进行配置。开关
模式只能由SMBUS和I / O捆扎配置。 GL850G-37也支持开关模式
高/全速/低速模式,上行端口可以绕过下行端口。这个功能只是
可在下游端口1中获得
--------Compliant to USB Specification Revision 2.0
**Support 4/3/2 downstream ports by I/O pin configuration
**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
**Performance: 6 MIPS @ 12MHz
**With 64-byte RAM and 2K mask ROM
**Support customized PID, VID by external EEPROM/vendor command/ SMBUS
**Support downstream port configuration by external EEPROM/vendor command/ SMBUS
--------Single Transaction Translator (STT)
**Single TT shares the same TT control logics for all downstream port devices. This is the most cost
effective solution for TT.
--------Integrate USB 2.0 transceiver
**Improve output drivers with slew-rate control for EMI reduction
**Internal power-fail detection for ESD recovery
--------Low BOM cost
**Built-in 5V to 3.3V regulator
**Built-in upstream 1.5KΩ pull high and downstream 15KΩ pull-down
**Built-in PLL supports external 12 MHz crystal / Oscillator clock input
**Embed serial resister for USB signals
--------Smart power consumption
**Support both individual and gang modes of power management and over-current detection for
downstream ports (Individual mode is not supported by SSOP 28 package)
**Conform to bus power requirements
--------Flexible design
**Number of Downstream port can be configured by I/O strapping without external EEPROM/vendor
command/ SMBUS
**Support compound-device (non-removable in downstream ports) by I/O strapping/vendor command/
SMBUS
**Automatic switching between self-powered and bus-powered modes
**Configurable non-removable device support
--------Available package:
**28 pin QFN (5x5mm) and 28 pin SSOP (209mil)
--------Applications:
**Stand-alone USB hub
**PC motherboard USB hub, Docking of notebook
**Gaming console
**LCD monitor hub
**Any compound device to support USB hub function
