DESCRIPTION
The ISSI IS61LV12816 is a high-speed, 2,097,152-bit static
RAM organized as 131,072 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 access times as fast as 10 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 IS61LV12816 is packaged in the JEDEC standard 44-
pin 400-mil SOJ, 44-pin TSOP (Type II), 44-pin LQFP, and
48-pin mini BGA (6mm x 8mm).
