Summary description

The M41T00SC64 is a low power, Serial Real Time Clock plus a 64Kb EEPROM (see Figure 3). A built-in 32,768Hz oscillator (crystal controlled) and the first 8 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 serially via a two-line, bi-directional bus. The built-in address register is incremented automatically after each WRITE or READ data byte. The M41T00SC64 clock has a built-in power sense circuit which detects power failures and automatically switches to the battery supply during power failures. The energy needed to sustain the clock operations can be supplied from a small lithium coin cell.

Typical data retention time for the Serial RTC is in excess of 9.5 years with a 50mAh, 3V lithium cell. The M41T00SC64 is supplied in an 18-lead Plastic SOIC package.
