FRAM device speeds into powertrain
systems
Automotive-temperature FRAM is a direct hardware replacement for equivalent EEPROMs, yet far superior because of its fast writes, virtually unlimited endurance and low operating currents.
Ramtron has expanded its line of +125C-qualified automotive FRAM devices The FM25L04-GA, a 4Kbit 3V serial peripheral interface (SPI) FRAM, is now Grade 1 AEC-Q100-specified to operate over the automotive temperature range of -40 to +125C and is guaranteed to retain data for 9000 hours at that extreme temperature

F-RAM qualifies for automotive duties
The FM24CL64 is a popular choice for automotive radio applications with its fast writes and high endurance.
The FM25L04-GA is already designed into advanced powertrain systems where FRAM is required to record data quickly and frequently so that the gearbox can continually adapt itself to changing driver behaviour and road conditions.
FRAM'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.
"Ramtron's FRAM has been accepted as a mainstream memory technology in intelligent automotive applications in the passenger cab and under the hood", says Duncan Bennett, Ramtron International Strategic Marketing Manager.
"Ramtron is growing its line of Grade 1 automotive parts to meet the emerging demands of automobile manufacturers worldwide".
The FM25L04-GA is a 4Kbit nonvolatile RAM with an industry-standard SPI that enhances the high-speed write capability of FRAM 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 9kh at +125C as well as 17 years at +55C and operates at 3V over the automotive temperature range.
The FM25L04-GA is available in a "green" 8-pin SOIC package.
