GENERAL DESCRIPTION  
FEATURES  
Cꢀ High-Speed 8051 Architecture  
One Clock-Per-Machine Cycle  
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  
DC to 33MHz Operation  
Single Cycle Instruction in 30ns  
Optional Variable Length MOVX to Access  
Fast/Slow Peripherals  
Dual Data Pointers with Automatic  
Increment/Decrement and Toggle Select  
Supports Four Paged Memory-Access Modes  
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.  
Cꢀ On-Chip Memory  
16kB/32kB/64kB Flash Memory  
In-Application Programmable  
In-System Programmable Through Serial Port  
1kB SRAM for MOVX
