DS89C430/DS89C440/DS89C450 Ultra-High-Speed Flash Microcontrollers
ABSOLUTE 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°C to +85°C
Storage Temperature Range……………………………………………………………………………………………….-55°C to +125°C
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.
