Digital ICs/DSP: Multichip Package Delivers 2-Mword By 32-Bit Asynchronous SRAM

Dec. 18, 2003

Housed in a 255-contact plastic ball-grid-array package that measures just 25 by 25 mm, the W82M32V-XBX multichip memory module provides up to 2 Mwords by 32 bits of asynchronous static memory. The module is available with access times of 12, 15, 17, or 20 ns and operates from a 3.3-V supply. It has three-state transistor-transistor-level-compatible outputs and is fully static: No clock or refresh signals are required. The module comes in commercial, industrial, and military temperature-range options. In lots of 1000 units, the commercial temp-range version costs $250 apiece. Delivery is four to six weeks.
