Supports Battery or Capacitor Backup

The processor companion includes commonly needed

CPU support functions. Supervisory functions

include a reset output signal controlled by either a

low V_DDcondition or a watchdog timeout. /RST goes

active when V_DDdrops below a programmable

threshold and remains active for 100 ms (max.) after

V_DDrises above the trip point. A programmable

watchdog timer runs from 60 ms to 1.8 seconds. The

timer may also be programmed for a delayed start,

which functions as a window timer. The watchdog

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

signal for 100 ms if not restarted by the host within

the time window. A flag-bit indicates the source of

the reset.

Description

The FM33256 and FM3316 are devices that integrate

FRAM memory with the most commonly needed

functions for processor-based systems. Major

features include nonvolatile memory, real-time clock,

low-V_DDreset, watchdog timer, nonvolatile event

counter, lockable 64-bit serial number area, and

general purpose comparator that can be used for a

power-fail (NMI) interrupt or other purpose. The

devices operate from 2.7 to 3.6V.

Each FM33xx provides nonvolatile RAM available in

memory capacity of 16Kb and 256Kb. 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.

A comparator on PFI compares an external input pin

to the onboard 1.5V 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. Additionally it offers an

event counter that tracks the number of rising or

falling edges detected on a dedicated input pin. The

counter can be programmed to be non-volatile under

V_DDpower or battery-backed using only V_BAK. If

V_BAKis connected to a battery or capacitor, then

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.

events will be counted even in the absence of V_DD

This is a product that has fixed target specifications but are subject

to change pending characterization results.
