256K x 16 HIGH SPEED ASYNCHRONOUS
CMOS STATIC RAM WITH 3.3V SUPPLY
ISSI®
AUGUST 2000
FEATURES
• High-speed access time:
— 7, 8, 10, 12, and 15 ns
• CMOS low power operation
• Low stand-by power:
— Less than 5 mA (typ.) CMOS stand-by
• TTL compatible interface levels
• Single 3.3V power supply
• Fully static operation: no clock or refresh
required
• Three state outputs
• Data control for upper and lower bytes
• Industrial temperature available

DESCRIPTION
The ISSI IS61LV25616 is a high-speed, 4,194,304-bit static
RAM organized as 262,144 words by 16 bits. It is fabricated
using ISSI's high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design tech-
niques, 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 IS61LV25616 is packaged in the JEDEC standard
44-pin 400-mil SOJ, 44-pin TSOP Type II, 44-pin LQFP and
48-pin Mini BGA (8mm x 10mm).

Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V,
input pulse levels of 0V to 3.0V and output loading specified in Figure 1.
2. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage.
