Ramtron qualifies 4-kilobit F-RAM memory device to +125C for powertrain apps
( 01 Feb 2008 )
Ramtron International Corporation’s FM25L04-GA is a 4Kb nonvolatile RAM with an industry-standard SPI that enhances the high-speed write capability of F-RAM technology. The device is a direct hardware replacement for equivalent EEPROMs, yet far superior because of its fast writes, virtually unlimited endurance, and low operating currents.
The FM25L04-GA reads and writes at bus speeds up to 10MHz and boasts an advanced write protection scheme to prevent inadvertent writes and data corruption. It is guaranteed to retain data for 9,000 hours at +125C degrees as well as 17 years at +55C degrees, and operates at 3 volts over the automotive temperature range.
The FM25L04-GA is designed into advanced powertrain systems where F-RAM is required to record data quickly and frequently so that the gearbox can continually adapt itself to changing driver behavior and road conditions. F-RAM’s No Delay writes and virtually unlimited endurance, coupled with a high-speed SPI interface, uniquely enables reliable data writes at maximum bus speed in this and other advanced automotive applications.
The FM25L04-GA is available in a “green” 8-pin SOIC package.
