High-Performance, Highly-Reliable and Instant Non-Volatile Memory in Low-Pin-Count Interfaces

Next-generation industrial and automotive systems need high-performance non-volatile memories to log user and sensor data continuously, over long periods of time, and to instantly capture system state data in the case of power loss. In these next-generation systems, there is also a need to reduce the number of microcontroller pins used to interface with external memories. This need is driving a conversion from parallel to low-pin-count serial interface memories. For these systems, Excelon-Ultra and Excelon-Auto families provide the highest-performance-to-date FRAMs with the addition of a 108-MHz low-pin-count QSPI interface with unlimited read/write endurance, fast writes, and instant non-volatility. Excelon-Ultra and Excelon-Auto are superior to battery backed SRAMs traditionally used in these systems due to higher reliability and a reduced maintenance requirement resulting from the elimination of batteries. Additionally, Excelon reduces the BOM cost by replacing a multi-component solution (SRAM + battery + power management controller) with a single chip solution. Excelon-Auto F-RAMs are AEC-Q100 qualified and Functional Safety compliant to meet the demanding data-logging requirements of Automotive Event-Data-Recorder (EDR) systems.

Programmable Logic Controller (PLC)

PLCs are required to continuously log real-time system data, and capture the system state data, automatically on power loss or system failure. This is required to enable efficient and safe factory operation as well as advancements like predictive analytics and preventive maintenance. Click here to learn why Excelon F-RAMs are the ideal memory for the highly demanding data-logging needs of PLCs.


ADAS Vision System

Camera-based Vision Systems form an integral part of ADAS and are the key to driver assistance functions, such as collision avoidance, and can also support the driver in reducing the severity of an accident. As motor vehicles become autonomous, there is an urgent need for the highest reliability event-data-recorders in ADAS Vision Systems, to ensure last event capture. Click here to learn how Excelon F-RAMs enable instant and reliable data-capture in ADAS Vision Systems.
