Non-volatile memory technology has extended temperature range for automotive applications

Fujitsu Electronics Europe has launched its new FRAM solution MB85RS256TY. It is the first component of a completely new product group which is designed for an operating temperature of up to 125C and is qualified according to the AEC Q100 industry standard, making it particularly suitable for use in the automotive sector. With the new series, the company wants to serve various applications in the automotive market and support innovative projects. The ever increasing demand from the automotive industry for electronic control systems, which access a wide variety of sensor data, has led to a growing demand for high-performance non-volatile memory technology. Only in this way can data collected by sensors be reliably stored without a delay - for example, for analysis purposes or for other forms of data processing. Because FRAM (ferroelectric RAM) is non-volatile, provides high-speed random access and has high write endurance, it satisfies the requirements of such applications in an optimal manner. FRAM reduces system complexity and increases data integrity by allowing instant and continuous data storage in applications such as air bag data storage, event data recorders (EDR), battery management systems (BMS), automatic driving assistance systems (ADAS) or navigation and infotainment systems. The new automotive FRAM product offers a 256kbit FRAM with SPI interface and an extended operating voltage range of 1.8V to 3.6V. The operating temperature of this device ranges from -40C to +125C. This extended temperature range meets the standard requests from the automotive market as well as industrial applications within hot environments. It offers a write endurance of 1013 and is housed in a standard SOP-8 package. “The automotive industry is undergoing the biggest transformation in its history”, says Dr. Klaus-Peter Dyck, senior manager marketing and application at FEEU. “With products such as our new FRAM solution we support innovative companies, enabling them to make their ideas a reality. We act as a gateway for components from all around the world while providing expert consultancy throughout each project. In this way, we find a solution for every challenge and accelerate our clients’ innovation process.”
