Ramtron Expands F-RAM Family with Automotive-grade 128kb Devices

Ramtron International Corp. has added two new serial ferroelectric RAM (F-RAM) devices to its V-Family product line that meet stringent AEC-Q100 Grade 3 automotive qualification standards. The FM24V01-G and FM25V01-G are 128kb high-performance nonvolatile F-RAM memories that operate over a wide operating voltage range of 2V to 3.6V. The rigorous automotive-grade qualification, established by the Automotive Electronic Council’s Stress Test Qualification for Integrated Circuits, serves the demanding requirements of the automotive market, ensuring reliable device operation over the automotive temperature range of -40°C to 85°C.

Featuring wide-voltage operation of 2V to 3.6V, the FM24V01-G and FM25V01-G are the newest members of Ramtron’s broad line of V-Family nonvolatile F-RAM memory products. The FM24V01, with a serial I2C interface, has an active current of 90µA (typical at 100kHz). The FM25V01 performs at full bus speed of 40MHz with an active current of 2.5mA over a standard Serial Peripheral Interface (SPI). F-RAM memory features NoDelay writes, virtually unlimited read/write cycles (10E14), and low power consumption. The devices are hardware drop-in replacements for 128kb serial EEPROM memories in automotive, industrial controls, metering, medical, military, gaming, and computing applications, among others. The FM24V01-G and FM25V01-G are offered in an industry standard 8-pin SOIC package.

The V-Family product line offers a device ID feature that reads out manufacturer and part number identification. The devices also offer an optional unique, read-only serial number that helps thwart counterfeiting by identifying a board or system.

Ramtron’s V-Family of F-RAM products is a line of serial I2C, serial SPI, and parallel memories with densities ranging from 128kb to 1Mb. In addition to high-performance nonvolatile F-RAM memory, serial V-Family products offer an optional unique 64-bit serial number. The serial number is comprised of a 16-bit unique customer ID (upon request), a 40-bit manufacturing serial number, and an 8-bit cyclic redundancy check for systems that require unique electronic numbering for added security.
