8x930Ax
UNIVERSAL SERIAL BUS
MICROCONTROLLER
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.
