Infineon Technologies have launched two advanced Ferroelectric RAM (F-RAM) memory devices in response to the growing demand in the automotive event data recorder (EDR) market. The company claims that the data-logging memory components, available in 1Mbit and 4Mbit densities, are specifically designed to capture and securely store critical data for extended periods instantly. Notably, the 1Mbit devices mark a significant milestone as they are the industry’s inaugural automotive-qualified serial F-RAMs. These new components are Automotive Electronics Council – Q100 standard (AEC-Q100) Grade 1 qualified, ensuring high automotive reliability, and they can operate effectively over an extended temperature range of -40°C to +125°C.

As per the press release, the devices boast exceptional performance, with rapid and dependable read/write capabilities at up to 50 MHz in SPI mode and up to 108 MHz in Quad SPI (QSPI) mode. Moreover, they offer an endurance of 10 trillion read/write cycles, making them ideal for data logging applications requiring capturing information at 10-microsecond intervals for over two decades. The device’s unique zero delay write capability empowers the system to capture and record crucial data until the last moment before an accident or any user-defined trigger event occurs. These devices operate efficiently within a 1.8 V to 3.6 V voltage range and are available in a standard 8-pin SOIC package. Apart from its outstanding endurance, the device is designed to retain data for over 100 years, even after a power loss. This feature ensures data integrity and longevity, making it a highly reliable choice for various applications.
