NM29A040080

General Description

The NM29A040080 are 4-Mbit and 8-Mbit Flash memories

features of the device are designed to provide the most cost

effective solution for applications requiring low bandwidth

file storage Examples of these applications include digital

answering machines and personal digital recorders (digital

audio) or FAX and digital scanners (digital imaging) The

Serial Flash requires only a single 5V power supply has a

small erase block size (4 kbytes) and a low EMI serial inter-

face

The NM29A040080 have been designed to work seam-

lessly

with

National’s

family

(eg

NSAM266) of processors In this manner National is able to

provide the complete system solution to digital audio re-

cording (processor CODEC Flash memory software) or

digital imaging
