2Mb Ultra-Low Power Asynchronous CMOS SRAM
256K × 8 bit
Overview
The N02L83W2A 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 ON
Semiconductor’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
N02L83W2A 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. 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.
