FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION The ISSI IS61/64WV204816ALL/BLL are high-speed, 32M bit static RAMs organized as 2048K 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 CS# is HIGH (deselected), 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 device is packaged in the JEDEC standard 48-Pin TSOP (TYPE I) and 48-pin mini BGA (6mm x 8mm).
