Nonvolatile state saver retains logic states
The FM1105 and 1106 are said to be the industry’s first nonvolatile state savers—a device that saves the state of signals and restores them automatically upon power-up. The dual-logic-state devices use FRAM NV memory with its fast write time and virtually unlimited write endurance. They can be used to save the status of switches, relay, or LED drivers; for error flags; or for power-down detection, nonvolatile counters, and tamper indicators.
The chips need a supply current of less than 15 µA, while changing state at 1 kHz. They operate at 5 or 3.3 V over -40° to 85°C and come in a RoHS-compliant 8-pin SOT23 package. (From $0.36 ea/10,000—samples available now.)
