IS80C31 General Description
The ISSI IS80C51 and IS80C31 are high-performance microcontrollers fabricated using high-density CMOS technology. The CMOS IS80C51/31 is functionally compatible with the industry standard 80C51 microcontrollers.
The IS80C51/31 is designed with 4K x 8 ROM (IS80C51 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;a six-source, two-priority-level, nested interrupt tructure;and an on-chip oscillator and clock circuit. The IS80C51/31 can be expanded using standard TTL compatible memory.

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.
