GENERAL DESCRIPTION
The ICSI IS80C52 and IS80C32 are high-performance m i c r o c o n t r o l l e r fabricated using high-density CMOS t e c h n o l o g y . The CMOS IS89C52/32 is functionally c o m p a t i b l e with is the industry standard 80C52/32 microcontrollers. 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 expansion or full duplex UART; three 16-bit timer/counters; a n eight-source, two-priority-level, nested interrupt structure; and an on-chip oscillator and clock circuit. The I S 8 0 C 5 2 / 3 2 can be expanded using standard TTL compatible memory.
