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

While CLK is high or low, the QN outputs do not change regardless of the state of the data inputs. See truth table. Enable. This active-high input enables the device. When low, inputs are ignored and updates to the nonvolatile cells are prevented. When high, the device operates normally. Power Supply (2.7V to 3.6V) Ground

Description
Nonvolatile storage applied to logic is a 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 activelow 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 tristated. The enable pin may be tied to VDD since the device integrates a power management circuit that monitors the VDD level during power cycles.

Slope measured at any point on VDD waveform. After power up, when EN goes high the nonvolatile latches are read and the values restored to the outputs QN. After power up, this is the minimum time required before a state change operation may occur. EN and VDD may be coincident at power up, and in this case tEHFC time is referenced to VDD (min) and CLK .
