2Mb Serial Nonvolatile F-RAM Memory
07 February 2012
Ramtron International has released the FM25V20, a 2Mb high performance serial F-RAM device.
The FM25V20 is a member of Ramtron’s V-Family of F-RAM products, which offers a wide operating voltage range of 2.0 to 3.6 volts. The FM25V20 features fast access, NoDelay writes, virtually unlimited read/write cycles (1e14), and low power consumption.
The latest F-RAM device is a drop-in replacement for 2Mb serial Flash and serial EEPROM memories in a number of applications including industrial controls, metering, medical, military, gaming, and computing applications.
“The FM25V20 provides more non-volatile memory capacity for demanding data collection applications as well as an easy upgrade path to higher densities for our current V-Family F-RAM customers,” said Ramtron’s, Craig Taylor. “The expansion of our V-Family product line supports our on-going initiative to provide low energy and high data integrity memory solutions that eliminate the complexities, overhead, and system level reliability issues often encountered with other nonvolatile memories.”
FM25V20 employs an advanced ferroelectric process that yields virtually unlimited endurance of 100-trillion (1e14) read/write cycles and reliable data retention for 10 years. The FM25V20 uses a fast serial peripheral interface (SPI), operating up to full bus speed of 40MHz frequency. The low power operation features a wide-voltage operation of 2.0V to 3.6V, a typical standby current of 100µA, and a sleep mode current of 3µA. A read-only Device ID feature, standard on the serial V-Family devices, allows the host to determine the manufacturer, product density, and product revision. The FM25V20 operates over an industrial temperature range of -40°C to +85°C and is available in standard ‘Green’/RoHS-compliant 8-pin EIAJ SOIC and 8-pin TDFN packages.
Manufactured on a low-power 130nm CMOS manufacturing process, the Ramtron V-Family of F-RAM products includes serial I2C, serial SPI, and parallel memories. The full V-Family line of F-RAM products includes the following devices:
The FM25V20 is sampling now in 8-pin EIAJ SOIC and TDFN packages.
