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.

Note: Load capacitors are integrated within the M41T00. Circuit board layout considerations for the 32.768kHz crystal of minimum trace
lengths and isolation from RF generating signals should be taken into account.
STMicroelectronics recommends the KDS DT-38 Tuning Fork Type quartz crystal for industrial temperature operations.
