Summary description
The M41T0 Real Time Clock is a low power Serial Real Time Clock with a built-in
32.768kHz oscillator (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 Outline package.
