GENERAL DESCRIPTION
The
ISSI
IS80LV51 and IS80LV31 are high-performance
microcontrollers fabricated using high-density CMOS
technology. The CMOS IS80LV51/31 is functionally
compatible with the industry standard 80C51
microcontrollers.
The IS80LV51/31 is designed with 4K x 8 ROM (IS80LV51
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 structure;
and an on-chip oscillator and clock circuit. The
IS80LV51/31 can be expanded using standard TTL
compatible memory.
