DS89C450 Datasheet PDF - Maxim Integrated

●GENERAL DESCRIPTION

●The DS89C430 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.
