... TT buffer for all downstream devices. Each downstream port of GL850 supports two-color (green/amber) status LEDs to indicate normal/abnormal status. The downstream ports of GL850 can be configured as individual mode or gang mode (4 ports as a group) for power management. Gang mode is very helpful for cost consideration, since we can use one poly-fuse, but not expensive power switch chips, to detect over current. GL850 passes the current requirement (< ...

... This pin is default put in input mode after power-on reset. Individual/gang mode is strapped during this period. After the strapping period, this pin will be set to output mode, and then B output high for normal mode. When GL850 is suspended, this pin (pd) will output low. *For detailed explanation, please see Chapter 5 ...

... The functionality of FRTIMER is described in section 11.2 of USB Specification Revision 2.0. 5.1.4 ôC ôC is the micro-processor unit of GL850 8-bit RISC processor with 2K ROM and 64 bytes RAM. It operates at 6MIPS of 12Mhz clock to decode the USB command issued from host and then prepares the data to respond to the host. In addition, ôC can handle GPIO (general purpose I/O) settings and reading content of EEPROM to support high flexibility for customers of different configurations of hub ...

... TT implements the control logic defined in section 11.14 ~ 11.22 of USB specification Revision 2.0. TT basically handles the unbalanced traffic speed between the USPORT (operating in HS) and DSPORTS (operating in FS/LS) of hub. GL850 adopts the single TT architecture to provide the most cost effective solution. Single TT shares the same buffer control module for each downstream port. ...

... Figure 5.3 - RESET# (External Reset) setting and application GL850 internally contains a power on reset circuit. The power on sequence is depicted in the next picture. To fully control the reset process of GL850, we suggest the reset time applied in the external reset circuit should more than that of the internal reset circuit. ...

... Figure 5.4 - Power on sequence of GL850 5.2.2 PGANG/SUSPND Setting To save pin count, GL850 uses the same pin to decide individual/gang mode as well as to output the suspend flag. The individual/gang mode is decided in the period of 1ms after power on reset. After that period of time, this pin is changed to output mode. GL850 outputs the suspend flag once it is globally suspended. For individual mode, a pull low resister greater than 100Kè ...

... Figure 5.6 - GANG Mode Setting 5.2.3 SELF/BUS Power Setting GL850 can operate under bus power and conform to the power consumption limitation completely (suspend current < 2.5 mA, normal operation current < 100 mA). By setting PSELF, GL850 can be configured as a bus-power or a self-power hub. 1: Power Self 0: Power Bus Figure 5.7 - SELF/BUS Power Setting © ...

... PGANG Figure 5.9 - Schematics Between GL850 and 93C46 GL850 firstly verifies the check sum after power on reset. If the check sum is correct, GL850 will take the configuration of 93C46 as part of the descriptor contents. To prevent the content of 93C46 from being over-written, amber LED will be disabled when 93C46 exists. ...

... Descriptors replied are different between full speed and high speed for an USB2.0 hub. Once an USB2.0 hub is plugged into a host/hub, it needs to firstly decide the host/hub is an USB1.1 host/hub or an USB2.0 host/hub. If the host/hub being plugged is an USB1.1 hub, GL850 replies to the host the full speed descriptors defined in section 6.2.1. Otherwise, GL850 replies the high speed descriptors defined in section 6.2.2. For hub class-specific descriptor, there’ ...
