Non-volatile F-RAM memory takes just 20µA
The FM25e64 64-Kbit F-RAM memory chip provides high endurance, symmetrical read/write speeds, and -40 to 85C operation. This version runs on either a 1.5- or 1.8-V supply and takes only 20 µA (typ.) active current at 1 MHz. It needs just 0.1 µA typical (5 µA maximum) in standby and takes only about 20-µs to start up, write data, and shut back down.
The 8-pin SOIC packaged IC runs at up to 20 MHz and has software and hardware write-protection. The IC is organized as 8,192 x 8 bits and features 1 Trillion read/write endurance, plus 36 year data retention at 75ºC. ($0.95 ea/10,000 — samples now, production Q3)
