The UT8SP2M40 is a high performance 83,886,080-bit synchronous static random access memory (SSRAM) device that is organized as 2M words of 40 bits. This device is equipped with
three chip selects (CS0, CS1, and CS2), a write enable (WE), and an output enable (OE) pin, allowing for significant design flexibility without bus contention. The device supports a four
word burst function using (ADV_LD).  All synchronous inputs are registered on the rising edge of the clock provided the Clock Enable (CEN) input is enabled LOW.  Operations are suspended when CEN is disabled HIGH and the previous operation is extended. Write operation control signals are WE and six byte write enables BWE[5:0]. All write operations are performed by internal self-timed circuitry.
