5V IIC FRAMs developed using 0.18µm technology

Fujitsu Semiconductor is sampling its new FRAMs based on the 0.18µm technology. This series features an IIC interface and operates at a voltage of 5V. The FRAM standalone memory devices are widely used in metering and factory automation applications as well as various industrial segments, where data logging, high speed write access and high endurance is essential.

The new 5V IIC FRAM family incorporates two devices: the MB85RC16V and MB85RC64V, which represent two density levels of 16Kbit and 64Kbit, respectively. All devices operate at a voltage range between 3V and 5.5V, and provide an endurance of 1 trillion write/read cycles as well as 10 years of data retention at 85°C. The maximum operating frequency for these products is 400kHz, and are well-suited for low power applications. The products are offered in 8-pin plastic SOP packages with standard memory pin assignment, making them fully compatible with E2PROM devices.

Aside from the I²C FRAM family, Fujitsu also offers SPI FRAM standalone devices with parallel interfaces with density levels varying from 16Kbit to 4Mbit. Fujitsu intends to expand its FRAM portfolio to meet market requirements. FRAM can ideally replace all battery back-up solutions and enable environmentally-friendly products.

With in-house development and manufacturing capabilities, Fujitsu is able to ensure close co-operation between design and production. This provides the basis for a stable supply chain, thus allowing Fujitsu to bring a substantial and high-quality product to market.
