GENERAL DESCRIPTION

The DS89C430, DS89C440, and DS89C450 offer the

highest performance available in 8051-compatible

microcontrollers.

processor cores that execute instructions up to 12

times faster than the original 8051 at the same

crystal speed. Typical applications will experience a

speed improvement up to 10x. At 1 million

instructions per second (MIPS) per megahertz, the

microcontrollers achieve 33 MIPS performance from

a maximum 33MHz clock rate.
