GENERAL DESCRIPTION
The DS89C420 offers the highest performance
available in 8051-compatible microcontrollers. It
features a redesigned processor core that executes
every 8051 instruction (depending on the instruction
type) up to 12 times faster than the original for the
same crystal speed. Typical applications see a speed
improvement of 10 times using the same code and
crystal. The DS89C420 offers a maximum crystal
speed of 33MHz, achieving execution rates up to 33
million instructions per second (MIPS).
The DS89C430 ultra-high-speed flash microcontroller
is an improved version of the DS89C420. The device
offers
more
features,
programming, for approximately the same price.
Engineers
