General Description
M41T00 General Description
The M41T00 TIMEKEEPER® RAM is a low power Serial TIMEKEEPER with a built-in 32.768kHz oscillator (external crystal controlled). Eight bytes of the RAM are used for the clock/calendar function and are configured in binary coded decimal (BCD) format. Addresses and data are transferred serially via a two-line bi-directional bus. The built-in address register is incremented automatically after each write or read data byte.

Note: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to the absolute maximum rating conditions for extended periods of time may affect reliability.
CAUTION: Negative undershoots below 0.3V are not allowed on any pin while in the Battery Back-up mode.
