Description

Nonvolatile

storage

applied

logic

revolutionary concept. The FM1106 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 FM1106 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.
