SUMMARY DESCRIPTION
The M41T0 TIMEKEEPER® RAM is a low power
Serial TIMEKEEPER with a built-in 32.768kHz os-
cillator (external crystal controlled). Eight registers
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 is incremented automatically after each
WRITE or READ data byte.
The M41T0 is supplied in 8 lead Plastic Small Out-
line package.
