3.3V REVOLUTIONARY PINOUT
SEPTEMBER 2000
FEATURES
DESCRIPTION
• High-speed access times:
8, 10, 12 and 15 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
• CE power-down
• Fully static operation: no clock or refresh
required
• 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)
The ISSI IS63LV1024 is a very high-speed, low power,
131,072-word by 8-bit CMOS static RAM in revolutionary
pinout. The IS63LV1024 is fabricated using ISSI's
high-performance CMOS technology. This highly reliable
process coupled with innovative circuit design
techniques, yields higher 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 to 250 µW (typical) with CMOS input levels.
The IS63LV1024 operates from a single 3.3V power
supply and all inputs are TTL-compatible.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation of the
device at these or any other conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.

Notes:
1. Test conditions assume signal transition times of 3ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V and
output loading specified in Figure 1a.
2. Tested with the load in Figure 1b. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
3. The internal write time is defined by the overlap of CE LOW 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.
