The FM1106 is an innovaTIve FRAM-based devicethat stores inputs like convenTIonal logic and retainsthe stored state in the absence of power. This productsolves three basic problems in an elegant fashion.First, it provides conTInuous access to nonvolaTIlesystem settings without performing a memory readoperation or using dedicated processor I/O pins.Second, it allows the storage of signals that maychange frequently and possibly without notice. Third,it allows the nonvolatile storage of a system settingwithout the system overhead and extra pins of a serialmemory.Functionally, the inputs are stored and passed to theoutput on the rising edge of the clock CLK. Thisunique product serves a variety of applications. Hereare a few applications:! Control relays or valves with automatic settingon power-up without processor intervention! Interface to soft/momentary front-panel switchand indicator lamp. Capture switch settings anddrive LEDs without processor intervention! Replaces jumpers & control signal routing! Initialize state of I/O card signals! Eliminate the overhead of serial memory forsystems needing only a bit of data
