NOVEMBER 1998  
8-BIT MICROCONTROLLER  
GENERAL DESCRIPTION  
FEATURES  
The ISSI IS80C52 and IS80C32 are high-performance  
microcontrollers fabricated using high-density CMOS  
technology. The CMOS IS80C52/32 is functionally  
compatible with the industry standard 8052/32  
microcontrollers.  
• 80C51 based architecture  
• 8K x 8 ROM (IS80C52 only)  
• 256 x 8 RAM  
The IS80C52/32 is designed with 8K x 8 ROM (IS80C52  
only); 256 x 8 RAM; 32 programmable I/O lines; a serial  
I/O port for either multiprocessor communications, I/O  
expansionorfullduplexUART;three16-bittimer/counters;  
an eight-source, two-priority-level, nested interrupt  
structure; and an on-chip oscillator and clock circuit. The  
IS80C52/32 can be expanded using standard TTL  
compatible memory.  
• Three 16-bit Timer/Counters  
• Full duplex serial channel  
• Boolean processor  
• Four 8-bit I/O ports, 32 I/O lines  
• Memory addressing capability  
– 64K ROM and 64K RAM  
• Program memory lock  
– Encrypted verify (32 bytes)  
– Lock bits (2)  
• Power save modes:  
– Idle and power-down
