It consists of standard 8XC251Sx peripherals plus a USB module. The USB module provides both USB hub and USB embedded function capabilities. The 8 x930Hx 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 x930Hx uses the standard instruction set of the MCS 251 architecture, which is binary code compatible with the MCS 51 architecture. |
