Ramtron International, a developer and supplier of non-volatile ferroelectric random access memory (F-RAM) and integrated semiconductor products, has unveiled two new serial nonvolatile F-RAM products.
According to Ramtron, the new 256-Kilobit (Kb) devices are part of its V-Family of F-RAM products. These include the FM24V02, a two-wire (I2C) interface and the FM25V02 with serial peripheral interface (SPI). These devices operate at a voltage range of 2.0 to 3.6-volts in an 8-pin SOIC package.
The company claims the new devices to offer fast access, NoDelay writes, virtually unlimited read/write cycles and low power consumption.
Ramtron said, the FM24V02 performs write operations up to the full I2C bus speed of 3.4 MHz, while supporting legacy timing for 100 kHz and 400 kHz. It offers up to 100-trillion (1E14) read/write cycles and its write operations do not require an internally elevated power supply voltage for write cirtuits. The FM24V02 operates at 150 microamps at 100 kHz, with 90 microamps in standby and 5 microamps during sleep mode.
The FM25V02 consumes 3 milliamps while running at a 40 MHz SPI clock rate, 90 microamps during standby, and 5 microamps during sleep mode. It offers an active power consumption of 38 microamps per MHz, the company said.
Mike Peters, marketing manager of Ramtron, said: The 256-Kilobit V-Family serial devices are lower voltage, higher performance alternatives to our existing 256 Kb serial products, specifically the FM24L256 and FM25L256B. Our expanding V-Family product line supports our environmental commitment to provide power-efficient nonvolatile memory, while eliminating the need for batteries.
