3 / 8 page  FM1112 NV Quad State Saver Rev. 1.0 Aug. 2007 Page 3 of 8 Description Nonvolatile storage applied to logic is a revolutionary concept. The FM1112 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 FM1112 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. |
