IC80LV51  
IC80LV31  
CMOS SINGLE CHIP  
LOW VOLTAGE  
8-BIT MICROCONTROLLER  
FEATURES  
GENERAL DESCRIPTION  
• 80C51 based architecture  
• 4K x 8 ROM (IC80LV51 only)  
• 128 x 8 RAM  
The ICSI IC80LV51 and IC80LV31 are high-performance  
microcontrollers fabricated using high-density CMOS  
technology. The CMOS IC80LV51/31 is functionally  
compatible with the industry standard 80C51 micro-  
controllers.  
• Two 16-bit Timer/Counters  
• Full duplex serial channel  
• Boolean processor  
The IC80LV51/31 is designed with 4K x 8 ROM (IC80LV51  
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  
IC80LV51/31 can be expanded using standard TTL  
compatible memory.  
• Four 8-bit I/O ports, 32 I/O lines  
• Memory addressing capability  
– 64K ROM and 64K RAM  
• Programmable lock  
– Lock bits (2)  
• Power save modes:  
– Idle and power-down  
• Six interrupt sources  
• Most instructions execute in 0.5 µs  
• CMOS and TTL compatible
