General Description
The NM29A040/080are 4-Mbitand 8-Mbit Flash memories
designed witha MICROWIRETM serial interface.Allofthe
featuresofthe deviceare designedto providethe most cost
effective solutionfor applications requiringlow bandwidth
file storage. Examplesof these applications include digital
answering machinesand personal digital recorders (digital
audio)or FAX and digital scanners (digital imaging). The
Serial Flash requires onlya single5V power supply,hasa
small erase blocksize(4 kbytes)andalow EMI serial inter-
face.
The NM29A040/080 have been designedto work seam-
lessly with National’s CompactRISCTM family (e.g.
NSAM266)of processors.Inthis manner Nationalis ableto
providethe complete system solutionto digital audiore-
cording (processor, CODEC, Flash memory, software)or
digital imaging.
