com GENERAL DESCRIPTION The DS89C430, DS89C440, and DS89C450 offer the highest performance available in 8051-compatible microcontrollers.
They feature newly designed 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.
The Ultra-High-Speed Flash Microcontroller User’s Guide should be used in conjunction with this data sheet.
