Non-Volatile SRAM Family
Cypress Semiconductor Corporation introduces the first products in a family of non-volatile SRAMs (nvSRAMs) that internally store data when power is lost, with no battery required. The nvSRAMs are appropriate for any application requiring continuous high-speed writing of data and absolute non-volatile data security, such as RAID (Redundant Array of Independent Disks) applications, copiers, PoS terminals, handheld meters and consumer electronics products. These nvSRAMs use a charge stored on an external capacitor instead of a battery, allowing the devices to be manufactured on a standard PCB assembly process. Operating with access times of 25 ns, the nvSRAMS are available in 1 Mbit/3 V, 256 kbit/3 V, 256 kbit/5 V, 64 kbit/5 V and 16 kbit/5 V configurations. The devices are highly scalable, with all of the configurations available in 32-pin SOIC packages and the 1-Mbit and 256-kbit devices also available in 48-pin SSOP packages.
