DS89C430
DESCRIPTION
The DS89C430 and DS89C450 offer the highe st performance available in 8051- 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 k B version of th e DS89C450 that is no lo nger available. The DS8 9C450 can be used as a drop-in replacement.
