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……………………………………………………………...-40°C to +85°C
Storage Temperature (Note 1)…………………………………………………………….-55°C to +125°C
Soldering Temperature………………………………………………………………+260°C for 10 seconds
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.
Note 1: Storage temperature is defined as the temperature of the device when VCC = 0V and VLI = 0V. In this state
the contents of SRAM are not battery-backed and are undefined.
