Extremely Accurate I2C RTC with
Integrated Crystal and SRAM
ABSOLUTE MAXIMUM RATINGS
RECOMMENDED OPERATING CONDITIONS
(TA = -40掳C to +85掳C, unless otherwise noted.) (Notes 2, 3)
Stresses beyond those listed under 鈥淎bsolute Maximum Ratings鈥� 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
absolute maximum rating conditions for extended periods may affect device reliability.
