Fujitsu Semiconductor's New 1 Mbit FRAM with I2C Interface Extends Industry-Leading Serial-Memory Lineup

MB85RC1MT is Ideal for Factory Automation, Instrumentation and Industrial Equipment, Can Replace EEPROMS, Serial FLASH in Many Applications

SUNNYVALE, Calif., Feb. 20, 2014 /PRNewswire/ -- Fujitsu Semiconductor America (FSA) today introduced the latest in its industry-leading family of FRAMs, the MB85RC1MT, with 1 Mbit of memory - the highest memory capacity of the company's products with an I2C serial interface.


The new MB85RC1MT is an excellent design choice for applications requiring frequent rewriting of data, such as real-time data logging for factory-automation, instrumentation, and industrial equipment. It operates between 1.8V and 3.3V in temperature ranges between -40 degrees C and 85 degrees C, and supports "high-speed" mode, which enables read and write at operating frequencies of 3.4MHz and at 1MHz, the same speed as conventional EEPROMs. The new FRAM guarantees 10 trillion write-erase cycles, which significantly exceeds the ability of EEPROMs. It can replace EEPROMs to enable high-precision data capture and reduced power consumption during data writing.

FRAM's non-volatility means that data is retained even when the power is switched off. Random access to its memory cells enables rapid data writing.

Since Fujitsu Semiconductor began volume production of FRAM products in 1999, these features have led to the wide use of FRAMs in applications such as factory automation equipment, instrumentation, financial terminals, and medical devices. The development of the MB85RC1MT adds to Fujitsu's FRAM products that use the I2C interface covering a full range from 4 Kbit to 1 Mbit.  In addition, FRAMs with the SPI interface range from 16 Kbit to 2 Mbits. All are offered in industry-standard 8-pin SOP packages to replace EEPROMs and serial Flash memories in a broad variety of applications with no need for major changes in PCB design.

Samples of the new MB85RC1MT are available now.

Fujitsu Semiconductor, leveraging its expertise in both design and manufacturing, has been recognized and awarded the 60th "Okochi Memorial Technology Prize" for the FRAM production technology development. Fujitsu Semiconductor continues to develop FRAM products designed to meet customers' requirements, including the smaller 512kbit MB85RC512T with the I2C interface. These low-power products are in increasing demand for applications such as energy harvesting where low voltage operation is essential.

Today’s connected world is moving from devices towards things, what this means is that by using increasingly low cost sensors embedded in devices we can create many new use cases. These span across use cases in cities, vehicles, home, offices, factories, retail environments, worksites, health, logistics, and health. These use cases rely on ubiquitous connectivity and generate massive amounts of data at scale. These technologies enable new business opportunities, ways to optimize and automate, al...
The web app is agile. The REST API is agile. The testing and planning are agile. But alas, data infrastructures certainly are not.

Old-style ad-hoc trial-and-error ways will certainly lead you to the dead end. What is mandatory is an overarching and adaptive approach to effectively handle the rapid changes and exponential growth.
