DESCRIPTION
The DS80C320/DS80C323 is a fast 80C31/80C32–
compatible microcontroller. Wasted clock and memory
cycles have been removed using a redesigned proces-
sor core. As a result, every 8051 instruction is executed
between 1.5 and 3 times faster than the original for the
same crystal speed. Typical applications will see a
speed improvement of 2.5 times using the same code
and same crystal. The DS80C320/DS80C323 offers a
maximum crystal rate of 33 MHz, resulting in apparent
execution speeds of 82.5 MHz (approximately 2.5X).
