Ramtron International Corporation has expanded its line of AEC-Q100-specified F-RAM memory devices, qualifying the FM24CL64 64-kilobit (Kb) serial F-RAM to operate over the Grade 3 automotive temperature range of -40 to +85 degrees Celsius. The FM24CL64 is part of Ramtron’s growing family of Grade 1 (+125C) and Grade 3 AEC-Q100-qualified automotive memory products.
The FM24CL64 is already designed into advanced automotive audio platforms in which F-RAM is used to record dynamic data quickly and frequently while maintaining data integrity even upon sudden power loss. The FM24CL64’s NoDelay™ writes, virtually unlimited endurance, and low operating currents, coupled with its I2C interface, uniquely enables reliable data collection/storage at maximum bus speed and low power in intelligent infotainment applications.
F-RAM in Intelligent Audio Systems
F-RAM collects and stores dynamic data to enable advanced radio features such as favorite artist/song alert, favorite station memory, and last channel recall. F-RAM’s low-power advantage also enables the collection/storage of traffic information while the vehicle is off so that drivers can access the most current data when they start the vehicle. F-RAM is also used to store digital sound parameters such as filter configuration and factory settings, as well as manual DSP and EQ settings, time delay adjustments for each channel, and advanced controls for crossover and filter settings on each channel.

About the FM24CL64
The FM24CL64 is a 64Kb nonvolatile RAM with an industry-standard I2C interface. The device is a direct hardware replacement for equivalent EEPROMs, yet far superior because of its fast writes, virtually unlimited endurance (1-trillion writes), 45 years of data retention, and low power consumption. The FM24CL64 operates at 3 volts over the Grade 3 automotive temperature range, draws 75 microamps (μA) for reads and writes at 100 kHz, and is available in a “green” 8-pin SOIC package.
