The 8x930Hx USB hub peripheral controller i s based on the MCS 251 microcontroller. It consists of standard
8XC251Sx peripherals plus a USB module. The USB module provides both USB hub

and USB embedded

function capabilities. The 8

x

930Hx supports USB hub functionality, embedded function, suspend/resume
modes, isochronous/non-isochronous transfers, and it is fully USB rev 1.0 specification compliant. The USB
module contains one internal and three (or four) external downstream ports and integrates the USB trans­ceivers, serial bus interface engine (SIE), hub interface unit (HIU), function interface unit (FIU), and
transmit /receive FIFOs. The 8

x

930Hx uses the standard instruction set of t he MCS 251 architecture, which is

binary code compatible with the MCS

51 architecture.
