Fujitsu Semiconductor Asia Pte Ltd has announced that it is currently sampling new FRAMs based on its 0.18?m technology. This series features an IIC interface and operates at a voltage of 5V.

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: MB85RC16V and MB85RC64V, which represent two density levels of 16Kbit and 64Kbit respectively. All devices operate at a voltage range between 3.0 and 5.5V and provide an endurance of 1 trillion write/read cycles as well as 10 years of data retention at 85C. The maximum operating frequency for these products is 400kHz, and they are well-suited for low power applications as well. The products are offered in 8-pin plastic SOP packages with standard memory pin assignment, making them fully compatible with EEPROM devices.

5V IIC FRAM lineup.

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.

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.
