General Description  
Features  
Y
g
Single 5V 10% power supply  
4 kbyte erase block  
The NM29A040/080 are 4-Mbit and 8-Mbit Flash memories  
designed with a MICROWIRETM 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.  
Y
Y
Organized as 128 (256) Blocks per 4-Mbit (8-Mbit)  
Device  
Ð 128 pages per block  
Ð 32 bytes per page (256 bits)  
MICROWIRETM compatible interface  
Low operating current (typical)  
Ð 5 mA read current  
Y
Y
Ð 15 mA write current  
Ð 10 mA erase current  
Ð 5 mA standby current  
The NM29A040/080 have been designed to work seam-  
lessly with National’s CompactRISCTM 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.

100k write/erase cycle endurance  
Offered in PLCC and SOIC packages
