White SRAM module meets height needs for E-Systems

Officials at E-Systems in Springfield, Mass., needed a static random access memory (SRAM) module with packaging height small enough to fit the needs for a classified military contract. The 16-bit SRAM module from White Microelectronics in Phoenix, Ariz., met their needs.

It came down to White and another supplier, and White won the E-Systems job because White`s packaging height was small enough to fit, says Brian Conant, an E-Systems representative.

The WS512K32-XG2X module, qualified under Standard Military Drawing 5962-94611, is housed in White`s dual-cavity gull-wing "G2" package designed to fit the JEDEC-standard .990-inch-square JLCC footprint.

The module is organized as 512K by 32, and is user configurable as 1M by 16 or 2M by 8. Access times range from 17 to 120 nanoseconds in commercial, industrial, and military temperature ranges.

Cofired ceramic layers allow a height of only 5.1 millimeters. The hermetically sealed package body is only 22.4 millimeters on a side, with leads extending to fit the JEDEC-standard 68-lead footprint. In addition, the number of solder connections is reduced from 128 or 144 respectively to 68 with the G2 package for the same memory density.

These SRAM modules are suitable for airborne, missile, satellite, radar, guidance, and ordnance systems.
