2Mb Ultra-Low Power Asynchronous CMOS SRAM
256K × 8 bit
Overview
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 -40
o
C to
+85
o
C and is available in JEDEC standard
packages compatible with other standard 256Kb x
8 SRAMs
