High Speed Inter-Chip (HSIC) USB 2.0 Hub and Flash Media Controller
Datasheet
SMSC USB4640/USB4640i
OEM Selectable Hub Features
A default configuration is available in the USB4640/USB4640i following a reset. The
USB4640/USB4640i may also be configured by an external I
flash.
Compound Device support on a port-by-port basis
- a port is permanently hardwired to a downstream USB peripheral device
Select over-current sensing and port power control on an individual or ganged (all ports together)
basis to match the OEM’s choice of circuit board component selection
Port power control and over-current detection/delay features
Configure the delay time for filtering the over-current sense inputs
Configure the delay time for turning on downstream port power
Bus- or self-powered selection
Hub port disable or non-removable configurations
Flexible port mapping and disable sequencing supports multiple platform designs
Programmable USB differential-pair pin location eases PCB layout by aligning USB signal lines
directly to connectors
Programmable USB signal drive strength recovers USB signal integrity using 4 levels of signal drive
strength
Indicate the maximum current that the 2-port hub consumes
Indicate the maximum current required for the hub controller
