N01M0818L1A
1Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
128Kx8 bit
Overview
Features
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
-40oC to +85oC and is available in JEDEC
standard packages compatible with other standard
256Kb x 8 SRAMs

1. When the device is in standby mode, control inputs (WE and OE), address inputs and data input/outputs are internally isolated
from any external influence and disabled from exerting any influence externally.
2. When WE is invoked, the OE input is internally disabled and has no effect on the circuit.
