N80515

The N80515 is a kind of stand-alone, high-performance, single-chip microcontroller based on the 8051 architecture. While maintaining all the 8051 operating characteristics, the device contains several enhancements which significantly increase design flexibility and overall system performance. With on-board A/D converter and watchdog timer, the device is ideal for motor control applications ranging from automotive engines to vending machines.

There are some features as follows: (1)8K*8 ROM; (2)256*8 RAM; (3)six 8-bit ports; 48 I/O lines; (4)three 16-bit timer/event counters; (5)reload, capture, compare capabilities on timer 2; (6)full-duplex serial port; (7)twelve interrupt sources; four priority levels; (8)8-bit A/D converter; (9)upward-compatible with 8051; (10)16-bit watchdog timer; (11)VPD provides stangcy current for 40 bytes of RAM; (12)boolean processor; (13)256 bit-adressable locations; (14)most instructives execute in 1s; (15)64K bytes program memory space; (16)64K bytes data memory space.

The following is about the absolute maximum ratings: (1)storage temperature: -65 to +150; (2)voltage on any pin with respect to ground (VSS): -0.5 to +7 V; (3)power dissipation: 2.0 W. Then is about the operating ratings: commercial devices: temperature (TA): 0 to +70; VCC: 5V±10%; ground (VSS): 0 V.
