FM30C256-S – RAMTRON

The FM30C256-S, manufactured by Ramtron, is a 256-kilobit (32,768 x 8) nonvolatile Ferroelectric Random Access Memory (F-RAM) device housed in a 20-pin Small Outline Integrated Circuit (SOIC) package. This memory utilizes ferroelectric technology, providing high endurance (typically 1E14 read/write cycles), low power consumption, and fast write speeds compared to traditional EEPROM or Flash memory. The device operates as a data collector, implying its suitability for applications requiring frequent data logging or buffering. Given the 20-pin SOIC footprint, the FM30C256-S likely incorporates a serial interface, such as SPI or I2C, for communication with a host microcontroller or processor. Specific operating voltage, temperature range, and data retention characteristics should be confirmed via the manufacturer’s datasheet.
