Product Summary

The AT43301-SU is a 5-port USB hub chip supporting one upstream and four downstream ports. The AT43301-SU connects to an upstream hub or host/root hub via Port0, while the other ports connect to external downstream USB devices. The hub re-transmits the USB differential signal between Port0 and Ports[1:4] in both directions. The AT43301-SU is designed for very low-cost bus-powered or self-powered hub applications and is available in a 24-lead SOIC and a 32-lead LQFP packages. The 32-lead version of the AT43301, the AT43301-AC, has a 48 MHz clock input. The AT43301-SUupports the 12 Mb/s full speed as well as 1.5 Mb/s slow speed USB transactions. To reduce EMI, the AT43301-SU’s oscillator frequency is 6 MHz even though some internal circuitry operates at 48 MHz.
