Pin Functions
SERIAL DATA INPUT DI
The DI pin is used for transferring in commands and data
Data is latched on the rising edge of SK
SERIAL DATA OUT DO
The DO pin is used for transferring out status and data Data
output will change following the falling edge of SK
CHIP SELECT CS
This signal indicates which device is selected When this
signal is inactive the device ignores SK This signal can be
tied to ground when there is only one Serial Flash device
The CS pin may be pulled high to reset command input
SERIAL DATA CLOCK SK
This is the standard synchronous MICROWIRE clock which
determines the rate of data transfer On each toggle one
data bit is shifted into or out of the Serial Flash

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 CompactSPEECHTM 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 and digital cameras Combining the
NM29A040 080 with the CompactRISC family of embedded
processors can enable complete solutions for image stor-
age
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
