Product Summary
The FM3130 integrates a real-time clock (RTC) and
FRAM nonvolatile memory. The device operates
from 2.7 to 3.6V.
The FM3130 provides nonvolatile FRAM which
features fast write speed and unlimited endurance.
This allows the memory to serve as extra RAM for
the system microcontroller or conventional
nonvolatile storage. This memory is truly nonvolatile
rather than battery backed.
The real-time clock (RTC) provides time and date
information in BCD format. It can be permanently
powered from external backup voltage source, either
a battery or a capacitor. The timekeeper uses a
common external 32.768 kHz crystal and provides a
calibration mode that allows software adjustment of
timekeeping accuracy.
