Overview
Introduction
The AT43312A is a 5 port USB hub chip supporting one upstream and four down-
stream ports. The AT43312A connects to an upstream hub or Host/Root Hub via Port0
and the other ports connect to external downstream USB devices. The hub re-trans-
mits the USB differential signal between Port0 and Ports[1:4] in both directions. A USB
hub with the AT43312A can operate as a bus-powered or self-powered through chip’s
power mode configuration pin. In the self-powered mode, port power can be switched
or unswitched. Overcurrent reporting and port power control can be individual or glo-
bal. An on-chip power supply eliminates the need for an external 3.3V supply.
The AT43312A supports the 12-Mb/sec full speed as well as 1.5-Mb/sec slow speed
USB transactions. To reduce EMI, the AT43312A’s oscillator frequency is 6 MHz even
though some internal circuitry operates at 48 MHz.
The AT43312A consists of a Serial Interface Engine, a Hub Repeater, and a Hub
Controller.
