A family of robust FRAM products targets the industrial and metering sectors with a voltage range of 3.0 V to 5.5 V. The FRAM V Series from Fujitsu Semiconductor Europe meets the main requirements of these markets, such as low power consumption, robustness, and high reliability. The higher operating voltage offered by the components leads to a higher signal-to-noise ratio. Plus, the FRAM aims for a more efficient design and logistics process by minimizing the number of components that need to be qualified and stocked at customer sites.
The V Series will offer products ranging from 16 kb to 256 kb, covering both I²C and SPI interfaces. The first two offerings from the new product series, MB85RC16V and MB85RC64V, feature I²C serial interfaces at an operating frequency of maximum 400 kHz, covering the densities of 16 kbit and 64 kbit respectively. In comparison to 3-V products, the devices deliver an active current consumption of 40 µA (typical at 400 kHz) while maintaining the 5-µA typical standby current. In addition, the products deliver 10 years’ data retention at 85°C, as well as an endurance of 1012 read/write cycles over the industrial temperature range of -40°C to +85°C.
MB85RC16V and MB85RC64V are in mass production. Additional devices incorporating 256 kbit with I²C or SPI interfaces also will launch later in 2012. All products of this series are or will be available in EEPROM-compatible 8-pin plastic SOP packages. For more information, view the data sheets.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
