GL85芯片规格书：
FEATURES:
l 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
l 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 reading external EEPROM
- Support downstream port configuration by reading external EEPROM
l 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. Multiple TT provides individual TT control logics for each downstream port.
This is a performance better choice for USB 2.0 hub. Please refer to GL852 datasheet for more
detailed information.
l Integrate USB 2.0 transceiver
l Each downstream port supports two-color status indicator, with automatic and manual modes compliant to USB specification Revision 2.0
l Built-in upstream 1.5K pull-up and downstream 15K pull-down
l Embed serial resister for USB signals
l Support both individual and gang modes of power management and over-current detection for
downstream ports
l Conform to bus power requirements
l Automatic switching between self-powered and bus-powered modes
l Support compound-device (non-removable in downstream ports) by I/O p
