NM29A040 080
4-Mbit 8-Mbit CMOS Serial FLASH E²PROM
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 family (e g
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
