2Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
256Kx8 bit
Overview
Features
The N02M0818L2A is an integrated memory
device intended for implanted life-support (Class 3)
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 N02M0818L1A, which is intended for
non life-support (Class 1 and 2) medical
applications. The device operates with two chip
enable (CE1 and CE2) controls and output enable
(OE) to allow for easy memory expansion. The
N02M0818L2A is optimal for various applications
where low-power is critical such as implanted
pacemaker devices. The device can operate over a
very wide temperature range of -20oC to +60oC
and is available in die form as well as in JEDEC
standard packages compatible with other standard
256Kb x 8 SRAMs
