5 / 22 page M41T0 Description 5/22 1 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. Figure 1. Logic diagram Figure 2.
