Overview

The FM1106 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
