General Description
The DS1341/DS1342 low-current real-time clocks (RTCs) are timekeeping devices
that provide an extremely low standby current, which permits longer life from
a power supply. The DS1341/DS1342 support high-ESR crystals, which broaden the
pool of usable crystals for the devices. The DS1341 uses a 6pF crystal, while
the DS1342 uses a 12.5pF crystal. These devices are accessed through an I2C
serial interface. Other features include two time-of-day alarms, two interrupt
outputs, a programmable square wave output, and a serial bus timeout
mechanism.
The clock/calendar provides seconds, minutes, hours, day, date, month, and
year information. The date at the end of the month is automatically adjusted
for months with fewer than 31 days, including corrections for leap year. The
clock operates in either 24hr or 12hr format
with an AM/PM indicator.
