GENERAL DESCRIPTION
The ISSI IS89C52 is a high-performance microcontroller
fabricated using high-density CMOS technology. The
CMOS IS89C52 is functionally compatible with the
industry standard 80C51 microcontrollers.
The IS89C52 is designed with 8-Kbytes of Flash
memory, 258 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;
an eight-source, two-priority-level, nested interrupt
structure; and an on-chip oscillator and clock circuit. The
IS89C52 can be expanded using standard TTL compatible
memory.
