N01M0818L1A
1Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
128Kx8 bit
Overview
The N01M0818L1A is an integrated memory
device
intended for non life-support (Class 1 or
2) medical applications.
This device
comprises a
1 Mbit Static Random Access Memory organized
as 131,072 words by 8 bits. The device is designed
and fabricated using NanoAmp’s advanced CMOS
technology with reliability inhancements for
medical users. The base design is the same as
NanoAmp’s N01M0818L2A, which has further
reliability processing for life-support (Class 3)
medical applications. The device operates with two
chip enable (CE1 and CE2) controls and output
enable (OE) to allow for easy memory expansion.
The N01M0818L1A 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
