DESCRIPTION
FEATURES
The ISSI IS63LV1024/IS63LV1024L is a very high-speed,
low power, 131,072-word by 8-bit CMOS static RAM in
revolutionarypinout.TheIS63LV1024/IS63LV1024Lisfab-
ricated using ISSI's high-performance CMOS technology.
This highly reliable process coupled with innovative circuit
design techniques, yields higher performance and low
powerconsumptiondevices.
• High-speed access times:
8, 10, 12 ns
• High-performance, low-power CMOS process
• Multiple center power and ground pins for
greater noise immunity
• Easy memory expansion with CE and OE
options
When CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be
reduced down to 250 µW (typical) with CMOS input levels.
• CE power-down
• Fully static operation: no clock or refresh
required
TheIS63LV1024/IS63LV1024Loperatesfromasingle3.3V
power supply and all inputs are TTL-compatible.
• TTL compatible inputs and outputs
• Single 3.3V power supply
• Packages available:
– 32-pin 300-mil SOJ
– 32-pin 400-mil SOJ
– 32-pin TSOP (Type II)
– 32-pin STSOP (Type I)
– 36-pin BGA (8mmx10mm)
• Lead-free Available
