DS80C310
The DS80C310 is pin compatible with the standard
80C32 and includes standard resources such as three
timer/counters, 256 bytes of RAM, and a serial port. It
also provides dual data pointers (DPTRs) to speed
block data memory moves. It also can adjust the speed
of MOVX data memory access between two and nine
machine cycles for flexibility in selecting external
memory and peripherals. The DS80C310 offers upward
compatibility with the DS80C320.
