2Mb Ultra-Low Power Asynchronous Medical CMOS SRAM

256Kx8 bit

Overview

The N02M0818L1A is an integrated memory

device intended for non life-support (Class 1 or

2) medical applications. This device comprises a

2 Mbit Static Random Access Memory organized

as 262,144 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 N02M0818L2A, 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 N02M0818L1A 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

standard packages compatible with other standard

256Kb x 8 SRAMs
