DESCRIPTION
The M41T00 TIMEKEEPER RAM is a low power
Serial TIMEKEEPER with a built-in 32.768 kHz
oscillator (external crystal controlled). Eigth 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 ad-
dress register is incremented automatically after
each write or read data byte.
