Ramtron International Corporation announces the availability of its 4 Mb F-RAM memory in a streamlined FBGA package. The FM22LD16 is a 3 V, parallel nonvolatile RAM in a 48-pin ball grid array (FBGA) package that features fast access, virtually unlimited read/write cycles and low power consumption. Pin-compatible with asynchronous static RAM (SRAM), the FM22LD16 targets industrial control systems, such as robotics, network and data storage applications, multi-function printers, auto navigation systems and a host of other SRAM-based system designs. The memory is also available in a 44-pin thin small outline plastic (TSOP) package. The FM22LD16 is organized as a 256K × 16 nonvolatile memory, accessed with an industry standard parallel interface. Access time is 55 ns and cycle time is 110 ns. The device reads and writes at bus speed for NoDelay? writes with endurance of at least 1E14 (100 trillion) writes and 10-year data retention. The FRAM is a drop-in replacement for standard asynchronous SRAMs, but far superior as it does not require a battery for data backup and is inherently more reliable due to its monolithic form.
