maximum crystal speed of 33 MHz, resulting in apparent execution speeds of 82.5 MHz (approximately

2.5X).

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.
