INTRODUCTION

The UT8R128K32 is a high-performance CMOS static RAM organized as 131,072 words by 32 bits. Easy memory expansion is provided by active LOW and HIGH chip enables (E1, E2), an active LOW output enable (G), and three-state drivers. This device has a power-down feature that reduces power consumption by more than 90 when deselected.
