N04L163WC1A
4Mb Ultra-Low Power Asynchronous CMOS SRAM
256K × 16 bit
Overview
The N04L163WC1A is an integrated memory
device containing a 4 Mbit Static Random Access
Memory organized as 262,144 words by 16 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 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 N04L163WC1A 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 16 SRAMs.
