Colorado Springs, Colo. - The FM24L256 from Ramtron International Corporation is a 256-kilobit, 2.7- to 3.6-volt nonvolatile F-RAM memory device with a high-speed serial I2C memory interface. The FM24L256 provides high-performance data collection in a tiny, 8-pin package, designed to cut costs and board space in a range of applications from multi-function printers to industrial motor controllers.
The FM24L256 performs write operations at bus speed without write delays and the next bus cycle can start immediately without the need for data polling. According to the company, the device offers write endurance that is orders of magnitude higher than EEPROM and uses much lower power during writes than EEPROM, since write operations do not require an internally elevated power supply voltage for write circuits.
The device is designed for nonvolatile memory applications requiring frequent or rapid writes. Examples range from data collection, where the number of write cycles may be critical, to demanding industrial controls, where the long write time of EEPROM can cause data loss.
The FM24L256 is a hardware drop-in replacement for serial EEPROM, and is available in industry standard 8-pin SOIC package, operates from 2.7 to 3.6 volts, and is rated over the industrial temperature range of -40 degrees C to +85 degrees C.
Samples of the FM24L256 are currently available in an 8-pin Green/RoHS SOIC (lead-free) package, with pricing starting at $4.56 in low volume.
