2Mb Ultra-Low Power Asynchronous CMOS SRAM
256K × 8 bit
Overview
Features
The N02L083WC2A is an integrated memory
device containing a 2 Mbit Static Random Access
Memory organized as 262,144 words by 8 bits. The
device is designed and fabricated using
NanoAmp’s advanced CMOS technology to
provide both high-speed performance and ultra-low
power. The device operates with two chip enable
(CE1 and CE2) controls and output enable (OE) to
allow for easy memory expansion. The
N02L083WC2A is optimal for various applications
where low-power is critical such as battery backup
and hand-held devices. The device can operate
over a very wide temperature range of -40oC to
+85oC and is available in JEDEC standard
packages compatible with other standard 256Kb x
8 SRAMs

1. When the device is in standby mode, control inputs (WE and OE), address inputs and data input/outputs are internally isolated
from any external influence and disabled from exerting any influence externally.
2. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.

1. Stresses greater than those listed above 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 operating section of this specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

1. Typical values are measured at Vcc=Vcc Typ., TA=25°C and not 100% tested.
2. This parameter is specified with the outputs disabled to avoid external loading effects. The user must add current required to drive
output capacitance expected in the actual system.
3. This device assumes a standby mode if the chip is disabled (CE1 high or CE2 low). In order to achieve low standby current all
inputs must be within 0.2 volts of either VCC or VSS.
