SUMMARY DESCRIPTION
The M41T00 TIMEKEEPER
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.
The M41T00 clock has a built-in power sense cir-
cuit which detects power failures and automatical-

failures. The energy needed to sustain the RAM
and clock operations can be supplied from a small
lithium coin cell.
Typical data retention time is in excess of 5 years
