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 M41T00 is incremented automatically after each write or read data byte.
