16MByte SRAM SIMM

White Microelectronics has introduced a 16MByte SRAM SIMM. This original design places eight 512K x 32 SRAM PLCCs on a 72-pin SIMM with laminate substrate and gold edge connectors. It offers 4.73Mbits per square inch, a 170 percent increase in density when compared to the industry standard 1MByte SRAM SIMM, at 2.77Mbits per square inch.

The WPS4M32-XMSC is organized as 4M x 32 and has access times of 25-, 35-, and 45ns. It operates on a 5V power supply; 3.3V parts are also available. JEDEC standard pinouts and presence detect pins allow use of multiple memory configurations on the same board design and upgrades from existing lower densities. Four chip selects provide the design flexibility of 8 bit, 16 bit, or 32 bit access. These features make the SIMM ideal for high-speed network switches, VME and DSP boards, and access servers.

The WPS4M32-XMSC has built-in decoupling caps, buffered inputs and outputs, and multiple ground pins for low noise operation.
