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.
1.1
Calibration
As the crystal is molded together with the silicon in this package, ST can program the
appropriate calibration value necessary to achieve ±5 ppm accuracy at 25°C after two SMT
reflows (see
Figure 4
). This calibration value will be written into address 1550h of
the EEPROM. This clock accuracy can then be guaranteed to drift no more than ±3 ppm the
first year, and ±1 ppm for each following year due to crystal aging.
