Description

Pin Configuration

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.
