General Description
DS89C450 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. 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.
DS89C450 Maximum Ratings
Voltage Range on Any Pin Relative to Ground..-0.3V to (VCC + 0.5V)
Voltage Range on VCC Relative to Ground.......-0.3V to +6.0V
Ambient Temperature Range (under bias).......-40 to +85
Storage Temperature Range..............-55to +125
Soldering Temperature...........See IPC/JEDEC J-STD-020
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only,and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to the absolute maximum rating conditions for extended periods may affect device reliability.
