DESCRIPTION The ISSI IS61LV3216L is a high-speed, 512K static RAM
organized as 32,768 words by 16 bits. It is fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields fast access times with low power consumption. When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be reduced down to 150 W (typical) with CMOS input levels. Easy memory expansion is provided by using Chip Enable and Output Enable inputs, CE and OE. The active LOW Write Enable (WE) controls both writing and reading of the memory.A data byte allows Upper Byte (UB) and Lower Byte (LB) access. The IS61LV3216L is packaged in the JEDEC standard 44-pin 400-mil SOJ and 44-pin TSOP (Type II).

Tested with the load in Figure 1b. Transition is measured 500 mV from steady-state voltage. Not 100% tested. 3. The internal write time is defined by the overlap of CE LOW and UB or LB, and WE LOW. All signals must be in valid states to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the rising or falling edge of the signal that terminates the write.
