DS80C310-MCL DALLAS [Dallas Semiconductor], DS80C310-MCL Datasheet - Page 2

• Manufacturer Part Number: DS80C310-MCL
• Description: High-Speed Micro
• Manufacturer: DALLAS [Dallas Semiconductor]

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.
