It consists of standard 8xC251Sx peripherals plus an added USB function. The 8x930Ax uses the standard instruction set of the MCS 251 architecture, which is binary code compatible with the MCS 51 architecture. The USB function integrates the USB transceiver, serial bus interface engine (SIE), function interface unit (FIU) and transmit/receive FIFOs. The USB function also supports full-speed/low-speed data rates, suspend/resume modes, isochronous/non-isochronous transfers, and is fully compliant with the USB rev 1.0 specification.
