Ramtron International Corporation (Nasdaq: RMTR), a leading developer and supplier of nonvolatile ferroelectric random access memory (F-RAM) and integrated semiconductor products, 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 -40ºC to +85ºC. The FM24CL64 is part of Ramtron’s growing family of Grade 1 (+125ºC) 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[tm] writes, virtually unlimited endurance, and low operating currents, coupled with its I2C interface, uniquely enable reliable data collection/storage at maximum bus speed and low power in intelligent infotainment applications.
“This achievement demonstrates Ramtron’s dedication to meeting the design and sourcing challenges of the automotive market,” explained Duncan Bennett, Ramtron International Strategic Marketing Manager. “The FM24CL64 is a popular choice for automotive radio applications with its fast writes and high endurance, which are ideal for recording continuously changing data that must be immediately available on power up.”
F-RAM in Intelligent Audio Systems
F-RAM collects and stores dynamic data to enable advanced radio features such as favourite artist/song alert, favourite 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 3V over the Grade 3 automotive temperature range, draws 75µA for reads and writes at 100KHz, and is available in a “green” 8-pin SOIC package.
