M41T00
Serial real-time clock
Features
■ For new designs use M41T00S
■ Counters for seconds, minutes, hours, day,
month, years, and century
■ 32 kHz crystal oscillator integrating load
capacitance (12.5 pF) providing exceptional
oscillator stability and high crystal series
resistance operation
■ Serial interface supports I2C bus (100 kHz
protocol)
■ Ultra low battery supply current of 0.8 A
(typ at 3 V)
■ 2.0 to 5.5 V clock operating voltage
■ Automatic switchover and deselect circuitry
(for 3 V application select M41T00S datasheet)
■ Software clock calibration to compensate
crystal deviation due to temperature
■ Automatic leap year compensation
■ Operating temperature of -40 to 85 °C
Description
The M41T00 is a low power serial real time clock
with a built-in 32.768 kHz oscillator (external
crystal controlled). Eight 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 bidirectional bus. The built-in address
register is incremented automatically after each
WRITE or READ data byte.
The M41T00 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 RAM and clock operations can be
supplied from a small lithium coin cell.
Typical data retention time is in excess of 5 years
with a 50 mA/h 3 V lithium cell (see Section 2.10:
Data retention mode for AC/DC characteristics).
The M41T00 is supplied in 8-lead plastic small
outline package.
