DESCRIPTION
The
RAM organized as 262,144 words by 16 bits. It is fabricated
using
reliable process coupled with innovative circuit design tech-
niques, yields high-performance and low power consumption
devices.
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 IS61LV25616 is packaged in the JEDEC standard
44-pin 400-mil SOJ, 44-pin TSOP Type II, 44-pin LQFP and
48-pin Mini BGA (8mm x 10mm).
