INTRODUCTION
The QCOTSTM UT7Q512 Quantified Commercial Off-theShelf product is a high-performance CMOS static RAM organized as 524,288 words by 8 bits. Easy memory expansion is provided by an active LOW Chip Enable (E), an active LOWOutput Enable (G), and three-state drivers. This device has a power-down feature that reduces power consumption by more than 90% when deselected.
