Description
The M41T0 real-time clock is a low power serial real-time clock with a built-in 32.768 kHz
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 bidirectional 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.
