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.
