Ramtron updates FRAM series with 256Kbit chips

Ramtron announced 256Kbit 3V FRAM chips with SPI interface — M25L256. These novelties are designed for consumer and industrial markets. According to the press release, most competing products have parallel interface and are 16% larger in size.


FM25L256 read and write performance is comparable to that of hi-speed memory types. From EEPROM or flash memory this nonvolatile FRAM differs by no write latency. Similar to RAM chips FM25L256 allow unlimited rewrite cycles, while EEPROM endures about a million of them. New chips that have 25MHz bus are pin-compatible with EEPROM that enables to swap memory types during development without performance losses. FM25L256 voltage ranges from 2.7V to 3.6V, while the temperature range is —40°C to +85°C. FM25L256 is already sampling in 8-pin SOIC package.
