FRAM chips from Cypress semiconductors are made available in 44-pin TSOPII package option for its 1 Mb parallel asynchronous interface F-RAM with extended temperature range of -40˚C to +105˚C for its 2 Mb Serial Peripheral Interface (SPI) F-RAM.
The advantage offered by Cypress' FRAM chips is they are package compatible with (pin-to-pin replacement) Cypress's battery integrated SRAM based nonvolatile memory for high-rel applications such as industrial, networking and automotive electronics.
The designers who have used SRAM based nonvolatile memories in their designs can now replace them with FRAM chips. By using a FRAM chips they don't need to worry about issues related to battery and also FRAM is more reliable for long usage.
FRAM can retain the data for one hundred years with no batteries. The new FRAM chips from Cypress also address another issue of operating temperature range, where 2 Mb SPI F-RAM is designed to operate in the range of -40°C to +105°C.
The 1 Mb parallel asynchronous interface F-RAM device in a 44-pin TSOPII package and the extended temperature range of -40˚C to +105˚C for the 2 Mb SPI F-RAM device in an 8-pin TDFN package are both available now.
Cypress gained FRAM capability after acquiring FRAM specialist Ramtron.
