GENERAL DESCRIPTION

The DS89C420 offers the highest performance

available in 8051-compatible microcontrollers. It

features a redesigned processor core that executes

every 8051 instruction (depending on the instruction

type) up to 12 times faster than the original for the

same crystal speed. Typical applications see a speed

improvement of 10 times using the same code and

crystal. The DS89C420 offers a maximum crystal

speed of 33MHz, achieving execution rates up to 33

million instructions per second (MIPS).
