2Mb Ultra-Low Power Asynchronous CMOS SRAM
128Kx16 bit
Features
Overview
The N02L6181A is an integrated memory device
containing a 2 Mbit Static Random Access Memory
organized as 131,072 words by 16 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 base design is the same as ON
Semiconductor’s N02L63W3A, which is processed
to operate at higher voltages. The device operates
with a single chip enable (CE) control and output
enable (OE) to allow for easy memory expansion.
Byte controls (UB and LB) allow the upper and
lower bytes to be accessed independently. The
N02L6181A 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 128Kb x
16 SRAMs.
