Ramtron gets Grade 1 automotive qualification for nonvolatile state savers
Ramtron International has announced that two of its nonvolatile state savers, the FM1105-GA and FM1106-GA, have received AEC-Q100 Grade 1 qualification. The state saver device saves the state of signals on demand and restores them to the correct state automatically upon power up. F-RAM technology uniquely enables this capability due to its fast write time, virtually unlimited write endurance, and low-power requirements.The
“The Ramtron state saver is an elegant solution that simplifies the design of system control functions. The state saver is unique because it remembers the stored output values without power,” explains Mike Peters, Ramtron marketing manager. “The AEC-Q100 Grade 1 qualification of the FM1105-GA and FM1106-GA helps grow our Grade 1 automotive compliant product portfolio, further enabling intelligent automotive applications that respond to the timeliest information available,” Peters adds.
The low-power nonvolatile state saver provides continuous access to nonvolatile system settings without reading a memory or consuming dedicated processor I/O pins. It enables storage of signals that may change frequently and without notice, and it allows the nonvolatile storage of system settings without the system overhead and extra pins of a serial memory.
The FM1105-GA operates from 4.5 volts to 5.5 volts with a standby current of 20 microamps. The FM1106-GA operates from 2.7 volts to 3.6 volts with a standby current of 8 microamps. Both devices can drive 10 milliamp loads, change state continuously as fast as 1 microsecond, offer 1E12 (1-trillion) state changes, and operate over the AEC-Q100 Grade 1 automotive temperature range (-40 degrees C to +125 degrees C).
