Fujitsu Releases 64 Kbit FRAM with Best-in-Class Operational Power Consumption

Non-volatile memory optimal for miniature, low power consumption uses

Fujitsu Electronics Pacific Asia Ltd.

Singapore, April 14, 2016

Fujitsu Electronics Pacific Asia Ltd. today announced the release of the MB85RC64T, 64Kbit FRAM* with the industry's lowest operational power consumption. Samples are now available.

This FRAM product uses the I2C interface that can operate at a maximum of 3.4 MHz, and which operates with a wide range of power supply voltage, from 1.8V to 3.6V. It features an extremely low average current of 170 μA when operating at 3.4 MHz, and of 80 μA when operating at 1 MHz.

Fujitsu has prepared an industry-standard 8-pin small outline package (SOP), and also a miniature 8-pin small outline non-leaded package (SON). This product is ideal for devices that require miniature electronic components with low power consumption, such as battery-operated wearable devices, measurement devices, and smart meters.

Fujitsu provides batteryless solutions for the wearable and IoT market using FRAM and its features of non-volatility, high-speed writing, high read/write endurance, and low power consumption.

Now, in response to the market demand for lower power consumption, Fujitsu has developed the MB85RC64T, 64Kbit FRAM that offers the lowest class of operating current among Fujitsu’s FRAM product line (Figure 1).

This product with I2C interface operates with a wide range of power supply voltage, from 1.8V to 3.6V, at up to 3.4MHz and offers as major features extremely low average current when operating (170 μA at 3.4 MHz, 80 μA at 1 MHz). It offers an approximately 80% reduction in operating power consumption compared with Fujitsu Semiconductor’s existing products (Figure 2), achieving the lowest industry class of operating power consumption for 64Kbit FRAM.

Fujitsu offers this product in an industry-standard 8-pin SOP, and also in a small-sized 8-pin SON. The mounting area for the SON is about 20% that of the SOP (Figure 3), and the mounting volume is 8% that of the SOP, making it optimal for applications requiring miniaturization.

The MB85RC64T, featuring low power consumption in a small package, is expected to be used as memory in such devices as battery-operated wearables and measurement devices, smart meters, and gas and water meters.

Fujitsu will continue to provide products and solutions to improve the values and convenience of customers’ applications.

Glossary and Notes

* FRAM:
Ferroelectric random-access memory. A type of memory that uses a ferroelectric file as capacitors that store data. Retains contents even when power is removed. Combines benefits of both ROM and RAM, with fast write speed, low-power consumption, and high read/write cycle endurance. Also known as FeRAM. Produced by Fujitsu Semiconductor since 1999.
