FUNCTIONAL BLOCK DIAGRAM

The ISSI IS66WV51216ALL/BLL is a high-speed, 8M
bit static RAMs organized as 512K 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 high-performance and low power consumption devices.

When CS1 is HIGH deselected or when CS2 is low deselected or when CS1 is low, CS2 is high and both LB and UB are HIGH, the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels.

Easy memory expansion is provided by using Chip Enable and Output Enable inputs. 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 IS66WV51216ALL/BLL is packaged in the JEDEC standard 48-pin mini BGA 6mm x 8mm and 44-Pin TSOP TYPE II . The device is aslo available for die sales.
