uring wide-voltage operation of 2.0 to 3.6-volts, 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. “The 128-kilobit F-RAM V-Family devices demonstrate stringent automotive-grade compliance and offer unique integrated security features,” comments Ramtron marketing manager, Mike Peters.
