Ramtron International Corporation: Ramtron Extends V-Family Product Line With Serial 256-Kilobit F-RAM
COLORADO SPRINGS, CO--(Marketwire - July 15, 2009) - Ramtron International Corporation (
"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.
About the F-RAM V-Family
Manufactured on the proven 130nm CMOS manufacturing process developed by Ramtron and Texas Instruments, the Ramtron V-Family of F-RAM products includes a variety of serial I2C, serial SPI, and bytewide parallel memories. The advanced manufacturing process enables improved device specifications and increased feature sets. In addition to the FM24V02 and FM25V02, the V-Family line of F-RAM products includes the following devices:
-- FM24V10 (1Mb Serial I2C F-RAM) -- FM25V10 (1Mb Serial SPI F-RAM) -- FM24V05 (512Kb Serial I2C F-RAM) -- FM25V05 (512Kb Serial SPI F-RAM) -- FM28V100 (1Mb Parallel F-RAM)
Pricing and Availability
Samples of the FM24V02 and FM25V02 are available now in a RoHS-compliant, 8-pin SOIC package. Unit pricing begins at $2.39 in 10K volume for the FM24V02 and $2.35 in 10K volume for the FM25V02.
