The MCM67C518 is a 589,824 bit synchronous static random access memory designed to provide a burstable, high–performance, secondary cache for the i486? and Pentium? microprocessors. It is organized as 32,768 words of 18 bits, fabricated with Motorola’s high–performance silicon–gate BiCMOS technology.

This device is ideally suited for systems that require wide data bus widths and cache memory. See Figure 2 for applications information.
