Fujitsu Semiconductor Releases New 1 Mbit FRAM Product with I2C Interface, Extending Serial-Memory Lineup
Suitable memory for Factory-Automation control, metering and industrial equipment
Yokohama, Japan, February 20, 2014 — Fujitsu Semiconductor announced the developed of a new FRAM product, the MB85RC1MT, with 1 Mbit of memory, the highest memory density of the company's products with an I2C serial interface. The new product is available in sample quantities starting today.
The new product is guaranteed for up to 10 trillion read/write cycles, and is optimum for use in applications requiring frequent rewriting of the data, such as real-time data logging for factory-automation, metering , and industrial equipment. Now with the broad range of lineup for both the I2C and SPI serial interface products, Fujitsu Semiconductor can offer its customers non-volatile memory products that best fit their requirements.
Larger View
FRAM is a type of memory that features both non-volatility, which allows data to be retained even when the power is switched off, and random access, which enables fast data writing. Especially noteworthy among non-volatile memory technologies, it guarantees maximum 10 trillion read/write cycles. Since Fujitsu Semiconductor began mass production of FRAM products in 1999, these features of FRAM have led to their wide use in such applications as factory-automation equipment, instrumentation, financial terminals, and medical devices.
Fujitsu Semiconductor recently developed a new addition to its FRAM lineup, the MB85RC1MT, with 1 Mbit of memory (128K word x 8 bit), the highest memory density of the company's products with the I2C serial interface.
The product operates at the voltage between 1.8 and 3.3V in the temperature range between -40 and 85 °C. As to operation frequency, the product supports "high-speed" mode, which enables read and write at 3.4MHz, as well as 1MHz operation, the same speed as conventional EEPROMs. It guarantees 10 trillion rewritings, which well exceeds conventional EEPROMs, and supports the frequent rewriting of the data, such as real-time data logging for I2C interface products, as well as ones with other interfaces. Furthermore, applications that have used other products with I2C interfaces, such as EEPROMs and microcontrollers, can now replace EEPROMs, with the new FRAM products, enabling high-precision data capture through high-frequency logging (Figure 1) and reducing the power consumption during the data writing (Figure 2).
The addition of the MB85RC1MT extends the line of FRAM products with the I2C interface to cover the range from 4 Kbit to 1 Mbit, and those with the SPI interface from 16 Kbit to 2 Mbit (Figure 3). These FRAM products are offered in industry-standard 8-pin SOP packages, so they can replace EEPROMs or serial Flash memories, used in applications such as factory-automation, metering, and industrial equipment, without the major change in the PCB design.
Fujitsu Semiconductor is highly acknowledged for its manufacturing, and has recently received the 60th "Okochi Memorial Technology Prize" for the FRAM production technology development. Leveraging its expertise on both the design and the manufacturing, Fujitsu will continue to provide high quality FRAM products which meet customer's requirements. The future product lineup will include low-power products which are increasingly demanded for applications such as energy harvesting, where low voltage operation is essential.
