DS87C530/DS83C530 EPROM/ROM Microcontrollers with Real-Time Clock

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

Operating Temperature Range………………………………………………………………………………….0°C to +70°C

Storage Temperature Range……………………………………………………………………...-55°C to +125°C (Note 1)

Soldering Temperature.…………………………………………………………See IPD/JEDEC J-STD-020 Specification

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.
