Underwriters Laboratory (UL) Recognized

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.

Description

The FM32L27x 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, 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 2.7 to 3.6V.

The FM32L27x family is software and pinout

compatible with the FM31L27x family which also

includes a real-time clock. The common features

allow a system design that easily can be assembled

with or without timekeeping by simply selecting the

FM31L27x or FM32L27x, respectively.

A general-purpose comparator compares an external

input pin to the onboard 1.2V reference. This is

useful for generating a power-fail interrupt (NMI) but

can be used for any purpose. The family also includes

a programmable 64-bit serial number that can be

locked making it unalterable.

Each FM32L27x provides nonvolatile RAM

available in sizes including 4Kb, 16Kb, 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.

Additionally the FM32L27x offers a dual event

counter that tracks the number of rising or falling

edges detected on dedicated input pins. The counter

can optionally be battery backed and even battery

operated by attaching a backup power source to the

VBAK pin. If VBAK is connected to a battery or

capacitor, then events will be counted even in the

absence of V_DD

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.
