Overview
Pin Configuration
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.

Data In
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:
