Infineon claims its 8- and 16-Mbit F-RAMs are highest density available today
Claimed to be the industry’s highest density serial F-RAMs, Infineon’s 8- and 16-Mbit Excelon F-RAM (ferroelectric RAM) devices are for non-volatile data logging requirements in automotive and industrial systems. The company said they help prevent data loss in harsh operating environments.
The memories feature a wide voltage operation from 1.71 to 3.6V and support up to 54Mbytes per second of data throughput over a low pin count interface. The Excelon F-RAMs are available in a RoHS-compliant, 24-ball FBGA package.
“With the increase of automation and the rapid growth of connected sensors, datalogging requirements are driving the need for higher density memories that capture data reliably and instantly in the event of a power loss,” observed Ramesh Chettuvetty, who heads the RAM product line at Infineon’s automotive division. He said the Excelon F-RAM devices offer performance and reliability for mission-critical data capture, without sacrificing low power operation.
According to Infineon, the latest F-RAMs deliver the industry’s lowest power, mission-critical non-volatile memory by combining low power operation with high-speed interfaces, instant non volatility and unlimited read/write cycle endurance. The read and write performance of the serial memories are equivalent to parallel-interface, battery-backed SRAMs with 35ns access time. The fast write speeds, endurance and energy efficiency make them suitable for data logging in automotive, industrial and medical applications.
Infineon offers a broad portfolio of serial and parallel F-RAM products with densities ranging from 4kbit to 16Mbit and which support a 1.8 to 5.5V operating voltage range. They feature virtually unlimited endurance of 100 trillion read and write cycles for high performance, high reliability, low cost, non volatile memories in automotive, industrial, computing, networking, smart meter and multifunction printer applications.
The industrial-grade 8- and 16-Mbit Excelon F-RAMs are capable of supporting operating temperatures up to 105 degrees C.
The AEC-Q100 qualified, automotive-grade 3 16-Mbit devices can also be ordered presently and are available in the same 24-ball FBGA package.
