V-Family 256 kb parallel F-RAM launched


Colorado Springs, CO, U.S.A. — (METERING.COM) — July 31, 2009 – The second parallel device in a family of new parallel and serial F-RAM products that offer higher speed read/write performance and lower voltage operation has been launched by Ramtron International Corporation.

The latest device in Ramtron’s V-Family of F-RAM products is the FM28V020, a 256 kb, 2.0 to 3.6 V, parallel non-volatile RAM in an industry standard 28-pin SOIC package that features fast access, NoDelay™ writes, virtually unlimited read/write cycles, and low power consumption. The FM28V020 may be used as a drop-in replacement for battery-backed SRAM in industrial control and metering, as well as other applications including medical, automotive, military, gaming, and computing applications, among others.

“The FM28V020 offers a number of enhancements over our existing 256 kb parallel memory devices and provides an easy upgrade path for battery backed SRAM or NVSRAM users,” states Mike Peters, Ramtron’s marketing manager. “Relative to our popular FM18L08, the FM28V020 provides improved access and cycle time, allows operation down to 2 V with a lower active current, and accesses page mode operation up to 40 MHz.”

The FM28V020 also provides data retention for over 10 years while eliminating the reliability concerns, functional disadvantages, and system design complexities of battery-backed SRAM (BBSRAM). Removing the battery from the system simplifies the manufacturing process, reduces system maintenance, and is more environmentally friendly due to the elimination of battery by-products.

In-system operation of the FM28V020 is similar to other RAM devices, allowing it to be used as a drop-in replacement for standard SRAM.

F-RAM memory is nonvolatile due to its unique ferroelectric memory process, making it ideal for nonvolatile memory applications that require frequent or rapid writes. The device operates over the full industrial temperature range of -40°C to +85°C.
