DESCRIPTION
廬
NOVEMBER 2000
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 8 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, 44-pin LQFP, and 48-pin mini
BGA (6mm x 8mm).
