DESCRIPTION  
The M41T00 TIMEKEEPER RAM is a low power  
®
Serial TIMEKEEPER with a built-in 32.768kHz os-  
cillator (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 serial-  
ly via a two-line bi-directional bus. The built-in ad-  
dress register is incremented automatically after  
each write or read data byte.
