Description

The AUK 60C31/P 60C51/P is a high-performance micro controller fabricated with AUK

high-density CMOS technology. The AUK CMOS technology combines the high speed and

density characteristics of MOS with the low power attributes of CMOS.

The 60C51 contains a 4K×8 ROM, a 128×8 RAM, 32I/O lines, two 16-bit counter/times, a

five-source, two-priority level nested interrupt structure, a serial I/O port for either multi-

processor communication, I/O expansion or full duplex UART, and on-chip oscillator and

clock circuists.

In addition, the device has tow software selectable modes of power reduction idle mode

and powerdown mode. The idle mode freezes the CPU while allowing the RAM, times, serial

port, and interrupt system to continue functioning.
