System Concepts
The NM29A040/080 are 4-Mbit and 8-Mbit NAND Flash de-
signed to provide the most cost effective solution for file
storage applications. These applications include digital au-
dio recording, digital image storage and data logging appli-
cations.
For digital audio storage, the NM29A040/080 have been
matched with National’s NSAM266 voice processor. Appli-
cations that can benefit from this combination include digital
answering machines, personal digital recorders, pagers and
voicemail systems. When combined with National Semicon-
ductor’s CompactSPEECH
TM
embedded software and the
NSAM266 processor, customers can quickly bring to market
systems capable of recording up to 15 minutes of audio on
a single 4 Mb device. Multiple NM29A040/080’s can be
used to extend the record time up to 2 hours.
Digital imaging applications include FAX machines, hand-
held
scanners

cameras.
Combining
the
Data logging applications can take advantage of the
NM29A040/080’s simple interface and nonvolatility to allow
simple 8-bit microcontroller based systems to have access
to over 4 Mb of storage. The nonvolatility ensures data in-
tegrity in remote, battery powered applications.
