4Mb Ultra-Low Power Asynchronous Medical CMOS SRAM

256Kx16 bit

Overview

The N04M163WL1A 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

available in a JEDEC standard BGA package
