Features
Compliant with Universal Serial Bus 3.0 Specification Revision 1.0
- 4 downstream ports for super-speed, high-speed, full-speed and low-speed traffic.
- Backward compatible with USB specification Revision 2.0, 1.1 and 1.0.
MTT(Mul t iple Transact ion Translator )
- One TT for each downst ream por t .
- Better data throughput when multiple downstream ports act on FS concurrently.
Support SMBUS to customize configurations
- SMBUS address is configurable by external SPI Flash or internal eFuse.
Support I2C to configure other chips on the same platform.
Compliant with USB Battery Charging Specification Revision 1.2 and other portable devices
- DCP Mode of BC 1.2.
- CDP Mode of BC 1.2.
- ACA-Dock functions of BC 1.2.
- Charger detection functions for upstream port’s charger which complies with BC1.2.
- D+/D– Divider Modes 2.0V/2.7V, 2.7/2.0V and 2.7/2.7V.
- D+/D- 1.2V Mode.
The Up Stream Port of the RTS5411 can detect the DSP it is connected to is a SDP, CDP, or DCP.
When the RTS5411 is connected to a charging port, it is allowed to draw more current from the DSP.
Support Gang mode and Individual mode for downstream port.
Support USB2.0 LPM-L1 function
Support USB3.0 U1/U2/U3 power saving mode
Integrated Fast 8051 microprocessor
Support serial flash for ISP function which can upgrade Firmware or configurations via USB directly.
Support EEPROM for ISP function which can upgrade configurations via USB directly.
Support 12MHz Crystal clock
Integrated 3.3V output LDO inside, the input range supports from 4.5V to 5.5V
Integrated 1.2V output switching regulator, the input range supports from 3.0V to 5.5V.
Support LED control function of indicating Downstream Ports transfer activity and over-current
condition.
