PROM
General Description
The NM29A040/080 are 4-Mbit and 8-Mbit Flash memories
designed with a MICROWIRE
TM
serial interface. All of the
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 NM29A040/080 have been designed to work seam-
lessly
with
National’s
CompactRISC
TM
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.
