FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The ISSI IS62LV12816BLL 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 high-performance
and low power consumption devices.
When CE is HIGH (deselected) or when CE is low and
both LB and UB are HIGH, 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 IS62LV12816BLL is packaged in the JEDEC standard
44-pin TSOP (Type II) and 48-pin mini BGA (6mm x 8mm).
