Ultra-High-Speed Flash Microcontrollers

GENERAL DESCRIPTION

The DS89C430 and DS89C450 offer the highe st

performance available in 8051-com patible

microcontrollers. They feature ne wly designed

processor cores that execute instructions up to 1 2

times faster than the original 8 051 at the same

crystal speed. Typical a pplications will experience a

speed improvement up to 10x. At 1 million

instructions per second (MIPS) per megahertz, the

microcontrollers achieve 33 MIPS performa nce from

a maximum 33MHz clock rate.

The DS89C440 is a 32 kB version of th e DS89C450

that is no lo nger available. The DS8 9C450 can be

used as a drop-in replacement.

The Ultra-High-Speed Flash Microcontroller User’s Guide should

be used in conjunction with this data sheet. Download it at
