The 8 x 930H x USB hub peripheral controller is 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 930H x 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 trans-

ceivers, serial bus interface engine (SIE), hub interface unit (HIU), function interface unit (FIU), and

transmit/receive FIFOs. The 8 x 930H x uses the standard instruction set of the MCS 251 architecture, which is

binary code compatible with the MCS 51 architecture.
