Download the DS89C440 datasheet PDF.
This datasheet also covers the DS8 variant, as both devices belong to the same ultra-high-speed flash microcontrollers family and are provided as variant models within a single manufacturer datasheet.
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.

ION 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.
