DESCRIPTION
The ISSI IS61WV12816BLL and IS64WV12816BLL are
high-speed, 2,097,152-bit static RAM organized as 131,072
words by 16 bits. They are fabricated using ISSI's high-
performance CMOS technology. This highly reliable process
coupled with innovative circuit design techniques, yields
access times as fast as 12 ns with low power consumption.
When CE 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, 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 IS61WV12816BLL and IS64WV12816BLL are packaged
in the JEDEC standard 44-pin TSOP (Type II) and 48-pin
mini BGA (6mm x 8mm).
