GENERAL DESCRIPTION
The
ISSI IS89C51 is a high-performance microcontroller
fabricated using high-density CMOS technology. The
CMOS IS89C51 is functionally compatible with the
industry standard 80C51 microcontrollers.
The IS89C51 is designed with 4-Kbytes of Flash
memory, 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;
an six-source, two-priority-level, nested interrupt structure;
and an on-chip oscillator and clock circuit. The IS89C51
can be expanded using standard TTL compatible memory.
