TTL compatible interface levels
Single 2.7V-3.6V Vcc power supply
Fully static operation: no clock or refresh re-
quired
Three state outputs
Data control for upper and lower bytes
Industrial temperature available
Available in the 44-pin TSOP-2 and 48-pin
6*8mm TF-BGA
DESCRIPTION
The
1+51
IS62LV12816L and IS62LV12816LL are high-speed,
2.097,152-bit static RAMs organized as 131,072 words by 16
bits. They are fabricated using
1+51
's high-performance CMOS
technology. This highly reliable process coupled with innova-
tive 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 by using CMOS
input levels.
Easy memory expansion is provided by using Chip Enable
Output and 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 IS62LV12816L and IS62LV12816LL are packaged in the
JEDEC standare 44-pin 400mil TSOP-2 and 48-pin 6*8mm
TF-BGA.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at these or any other conditions above
those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

of 0.4V to 2.2V and output loading specified in Figure 1.
2. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
