IC61LV5128
512K x 8 HIGH-SPEED CMOS STATIC RAM
FEATURES
• High-speed access times:
— 8, 10, 12 and 15 ns
• High-preformance, lower-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
reguired
• TTL compatible inputs and outputs
• Single 3.3V ± 10% power supply
• Packages available:
— 36-pin 400mil SOJ
— 44-pin TSOP-2
DESCRIPTION
The ICSI IC61LV5128 is a very high-speed, low power,
524,288-word by 8-bit COMS static RAM. The IC61LV5128 is
fabricated using ICSI's high-performance CMOS technology.
This highly reliable process coupled with innovative circuit
design techniques, yields higher preformance and low power
consumotion 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 IC61LV5128 operates from a single 3.3V power supply and
all inputs are TTL-compatible.
The IC61LV5128 is available in 36-pin, 400mil SOJ and 44-pin
TSOP-2 package.

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.

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.
