The 8x930Ax USB microcontroller is based on an 8xC251Sx microcontroller core. 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.
