FEATURES

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).

80C32–Compatible

High–speed architecture

High integration controller includes:

Two full–duplex hardware serial ports

13 total interrupt sources with six external

Available in 40–pin DIP, 44–pin PLCC and TQFP

– 8051 Pin and instruction set compatible

– Four 8–bit I/O ports

– Three 16–bit timer/counters

– 256 bytes scratchpad RAM

– Addresses 64KB ROM and 64KB RAM
