Serial 256 Kb FRAM Devices offer no write delays.
July 23, 2009 -
Respectively featuring 2-wire (I²C) interface and serial peripheral interface (SPI), FM24V02 and FM25V02 operate from 2.0-3.6 V and come in RoHS-compliant, 8-pin SOIC package. Nonvolatile products offer NoDelay(TM) writes and read-only Device ID, which allows host to determine manufacturer, product density, and product revision. Power consumption rates for FM24V02, which supports up to 100-trillion read/write cycles, is 150 µA at 100 kHz, 90 µA in standby, and 5 µA in sleep mode.

Ramtron Extends V-Family Product Line with Serial 256-Kilobit F-RAM
Two new serial low power, high performance F-RAM devices announced by Ramtron
COLORADO SPRINGS, CO - July 15, 2009 - Ramtron International Corporation (Nasdaq: RMTR), the leading developer and supplier of nonvolatile ferroelectric random access memory (F-RAM) and integrated semiconductor products, today announced two new serial nonvolatile F-RAM products that offer high-speed read/write performance, low voltage operation, and optional device features. The 256-Kilobit (Kb) devices, which are part of Ramtron's V-Family of F-RAM products, include the FM24V02, a two-wire (I2C) interface and the FM25V02 with serial peripheral interface (SPI). The serial I2C and SPI V-Family devices operate at a voltage range of 2.0 to 3.6-volts in an industry standard 8-pin SOIC package. The FM24V02 and FM25V02 feature fast access, NoDelay(TM) writes, virtually unlimited read/write cycles, and low power consumption. The devices are drop-in replacements for 256 Kb serial Flash and serial EEPROM memories in industrial controls, metering, medical, military, gaming, and computing applications, among others.
"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," explains Ramtron marketing manager, Mike Peters. "Our expanding V-Family product line supports our environmental commitment to provide power-efficient nonvolatile memory, while eliminating the need for batteries."
About the FM24V02 and FM25V02
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. No write delays are incurred and the next bus cycle may commence immediately without the need for data polling. In addition, the product offers up to 100-trillion (1E14) read/write cycles, which are orders of magnitude higher than EEPROM. The FM24V02 exhibits much lower power during writes than EEPROM since write operations do not require an internally elevated power supply voltage for write circuits. The FM24V02 operates at 150 microamps at 100 kHz, with 90 microamps in standby and 5 microamps during sleep mode.
The FM25V02 consumes only 3 milliamps while running at a 40 MHz SPI clock rate, 90 microamps during standby, and 5 microamps during sleep mode. The FM25V02 offers a typical active power consumption of 38 microamps per MHz, which is an order of magnitude lower current than similar serial Flash or EEPROM products.
A read-only Device ID, standard on both serial devices, allows the host to determine the manufacturer, product density, and product revision. An optional unique read-only serial number is also available, which can be used to identify a board or system with an ID that is different from any other host in the world. The FM24V02 and FM25V02 are guaranteed over an industrial temperature range of -40°C to +85°C.
