Fujitsu expands its memory range

News

Fujitsu Semiconductor America (FSA) has introduced the latest in its family of FRAMs. The MB85RC1MT has 1 Mbit of memory.

This, FSA says, is 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 -400C and 850C.

It 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 ten 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.
