2Mb Ultra-Low Power Asynchronous CMOS SRAM
128K × 16 bit
Features
Overview
The N02L63W2A 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 device operates with two chip enable
(CE1 and CE2) controls 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 and can also be used to
deselect the device. The N02L63W2A 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.

Note: Page mode operation is a method of addressing the SRAM to save operating current. The internal
organization of the SRAM is optimized to allow this unique operating mode to be used as a valuable power
saving feature.
The only thing that needs to be done is to address the SRAM in a manner that the internal page is left open
and 16-bit words of data are read from the open page. By treating addresses A0-A3 as the least significant
bits and addressing the 16 words within the open page, power is reduced to the page mode value which is
considerably lower than standard operating currents for low power SRAMs.
