Description
General part information
DS89C450 Series
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.The DS89C440 is a 32kB version of the DS89C450 that is no longer available. The DS89C450 can be used as a drop-in replacement.ApplicationsAutomated Test Equipment (ATE)Building Energy Control and ManagementBuilding Security and Door Access ControlConsumer ElectronicsData LoggingGaming EquipmentHVACIndustrial Control and AutomationMagstripe Reader/ScannerMotor ControlProgrammable Logic ControllersTelephonesUninterruptible Power SuppliesVendingWhite Goods (Washers, Microwaves, Etc.)
