PRELIMINARY INFORMATION
DECEMBER 2001
FEATURES
DESCRIPTION
The ISSI IS62VV12816LL is a high-speed, 2,097,152 bit
static RAMs 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.
• High-speed access time: 70, 85 ns
• CMOS low power operation
– 36 mW (typical) operating
– 9 µW (typical) CMOS standby
• Single 1.7V-1.95V VCC power supply
For the IS62VV12816LL, when CE is HIGH (deselected)
or 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.
• Fully static operation: no clock or refresh
required
• Three state outputs
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.
• Data control for upper and lower bytes
• Industrialtemperatureavailable
• Available in the 44-pin TSOP (Type II) and
48-pin mini BGA (7.2mm x 8.7mm)
The IS62VV12816LL is packaged in the JEDEC standard
44-pin TSOP (Type II) and 48-pin mini BGA (7.2mm x
8.7mm).

Notes:
1. WRITE is an internally generated signal asserted during an overlap of the LOW states on the CE and WE inputs and at least one of
the LB and UB inputs being in the LOW state.
2. WRITE = (CE) [ (LB) = (UB) ] (WE).
