4Mb Ultra-Low Power Asynchronous Medical CMOS SRAM
256Kx16 bit
Overview
Features
The N04M1618L1A is an integrated memory
device intended for non life-support (Class 1 or
2) medical applications. This device is a 4
megabit memory organized as 262,144 words by
16 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
N04M1618L2A, 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. Byte
controls (UB and LB) allow the upper and lower
bytes to be accessed independently and can also
be used to deselect the device. This device 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 a JEDEC standard BGA package
