Logic States Retained in Absence of Power
Outputs Automatically Restored at Power-up
Number of State Changes: 1012
Max tPD 50ns at 4.5V
Max Frequency 1 MHz
Overview
The FM1110 is an innovative FRAM-based device
that stores inputs like conventional logic and retains
the stored state in the absence of power. This product
solves three basic problems in an elegant fashion.
First, it provides continuous access to nonvolatile
system settings without performing a memory read
operation or using dedicated processor I/O pins.
Second, it allows the storage of signals that may
change frequently and possibly without notice. Third,
it allows the nonvolatile storage of a system setting
without the system overhead and extra pins of a serial
memory.
Functionally, the inputs are stored and passed to the
output on the rising edge of the clock CLK. This
unique product serves a variety of applications. Here
are a few applications:
! Control relays or valves with automatic setting
on power-up without processor intervention
! Interface to soft/momentary front-panel switch
and indicator lamp. Capture switch settings and
drive LEDs without processor intervention
! Replaces jumpers & control signal routing
! Initialize state of I/O card signals
! Eliminate the overhead of serial memory for
systems needing only a bit of data

Description
Nonvolatile storage applied to logic is a
revolutionary concept. The FM1110 simplifies the
design of system control functions. This product is
unique because it remembers the stored output
values in the absence of power. Any change in the
latched state is automatically written to a nonvolatile
ferroelectric latch. This function is possible due to
the fast write time and extremely high write
endurance of the underlying ferroelectric memory
technology.

Use of Enable Pin
The FM1110 has an enable pin that is intended to be
used in conjunction with a system reset. An active-
low reset may be tied directly to the EN pin. At
power-up, /RESET will be held low for some time
during which the data input and CLK pins will be
ignored. Once the system comes out of reset and EN
goes high, the outputs QN drive to the state that were
previously latched and the device operates normally.
When the EN pin is low, the outputs QN are tri-
stated.
The enable pin may be tied to VDD since the device
integrates a power management circuit that monitors
the VDD level during power cycles.
