FEATURES
DESCRIPTION
• High-speed access time:
12 ns: 3.3V + 10%
15 ns: 2.5V-3.6V
• CMOS low power operation:
50 mW (typical) operating
25 µW (typical) standby
The ISSI IS61/64WV3216BLL is a high-speed, 524,288-bit
static RAM organized as 32,768 words by 16 bits. It is
fabricated using ISSI's high-performance CMOS
technology. This highly reliable process coupled with inno-
vative circuit design techniques, yields access times as
fast as 12ns (3.3V + 10%) and 15ns (2.5V-3.6V) with low
power consumption.
• TTL compatible interface levels
• Fully static operation: no clock or refresh
required
When CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be
reduced down with CMOS input levels.
• Three state outputs
• Data control for upper and lower bytes
• Automotive Temperature Available
• Lead-free available
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.
DataShee
The IS61/64WV3216BLL is packaged in the JEDEC stan-
DataSheet4U.dcaormd 44-pin TSOP-II, and 48-pin mini BGA (6mm x 8mm).
