• TTL compatible interface levels
• Single 2.5V-3.0V VCC power supply
• Fully static operation: no clock or refresh
required
• Three state outputs
• Data control for upper and lower bytes
• Industrial temperature available
• Available in the 44-pin TSOP (Type II) and
48-pin mini BGA
DESCRIPTION
The
ISSI
IS62LV12816L and IS62LV12816LL are high-
speed, 2,097,152-bit static RAMs organized as 131,072
words by 16 bits. They are 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), 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 IS62LV12816L and IS62LV12816LL are packaged in the
JEDEC standard 44-pin TSOP (Type II) and 48-pin mini BGA.

Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0.4V to
2.2V and output loading specified in Figure 1.
2. The internal write time is defined by the overlap of CE LOW and UB or LB, and WE LOW. All signals must be in valid states
to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to
the rising or falling edge of the signal that terminates the write.
3. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
