Description

The processor companion includes commonly needed

CPU support functions. Supervisory functions

include a reset output signal controlled by either a

low VDD condition or a watchdog timeout. /RST

goes active when VDD drops below a programmable

threshold and remains active for 100 ms after VDD

rises above the trip point. A programmable watchdog

timer runs from 100 ms to 3 seconds. The watchdog

timer is optional, but if enabled it will assert the reset

signal for 100 ms if not restarted by the host before

the timeout. A flag-bit indicates the source of the

reset.

The FM3127x is a family of integrated devices that

includes the most commonly needed functions for

processor-based systems. Major features include

nonvolatile memory available in various sizes, real-

time clock, low-VDD reset, watchdog timer,

nonvolatile event counter, lockable 64-bit serial

number area, and general purpose comparator that

can be used for an early power-fail (NMI) interrupt or

other purpose. The family operates from 4.0 to 5.5V.

Each FM3127x provides nonvolatile RAM available

in sizes including 64Kb and 256Kb versions. Fast

write speed and unlimited endurance allow the

memory to serve as extra RAM 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.

This product conforms to specifications per the terms of the Ramtron standard warranty. The product has completed Ramtron’s

internal qualification testing and has reached production status.
