1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. Minimum DC input voltage is 0.5V. During transitions, inputs may undershoot to 2. 0V for periods less than 20 ns. Maximum DC voltage on output pins is Vcc + 0.5V which may overshoot to Vcc + 2.0V for periods less than 20 ns.
3. Operating temperature is for commercial products only defined by this specification.


Description

The IC80C31 are high-performance microcontroller fabricated using high-density CMOS technology. The CMOS IC80C51/31 is functionally compatible with the industry standard 80C51/31 microcontrollers.

The IC80C31 is designed with 4K x 8 ROM (IC80C51 only); 128 x 8 RAM; 32 programmable I/O lines; a serial I/ O port for either multiprocessor communications, I/O expansion or full duplex UART; two 16-bit timer/counters; an six-source, two-priority-level, nested interrupt structure;and an on-chip oscillator and clock circuit. The IC80C31 can be expanded using standard TTL compatible memory.
