Preliminary
FM1107
Nonvolatile 3V Dual State Saver
Features
Nonvolatile State Saver
• Logic States Retained in Absence of Power
• Outputs Automatically Restored at Power-up
• Unlimited Number of State Changes
• Max tPD 50ns at 2.7V
• Max Frequency 1 MHz
Overview
The FM1107 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

Notes
1. CLK = VSS, all other inputs at VDD or VSS.
2. To calculate device power dissipation, PD = CPD*VDD2*fi + CL*VDD2*fo, where fi is the input clk freq, fo is the output freq,
and CL is the output load capacitance. Active current IDD may be calculated as IDD = CPD*VDD*fi, assuming outputs are
floating.
3. VIN or VOUT = VSS to VDD.
4. This parameter is characterized but not tested.
