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).
