etary, high performance CMOS SuperFlash technology.
The split gate cell design and thick oxide tunneling
injector attain better reliability and manufacturability
compared with alternate approaches. The 29EE010/
29LE010/29VE010 write with a single power supply.
Internal Erase/Program is transparent to the user. The
29EE010/29LE010/29VE010 conform to JEDEC stan-
dard pinouts for byte-wide memories.
Featuring high performance page write, the 29EE010/
29LE010/29VE010 provide a typical byte-write time of
39 碌sec. The entire memory, i.e., 128K bytes, can be
written page by page in as little as 5 seconds, when using
interface features such as Toggle Bit or Data# Polling to
indicate the completion of a write cycle. To protect
against inadvertent write, the 29EE010/29LE010/
29VE010 have on-chip hardware and software data
protection schemes. Designed, manufactured, and
tested for a wide spectrum of applications, the 29EE010/
29LE010/29VE010 are offered with a guaranteed page-
write endurance of 10
4
or 10
3
cycles. Data retention is
rated at greater than 100 years.
The 29EE010/29LE010/29VE010 are suited for applica-
tions that require convenient and economical updating of
program, configuration, or data memory. For all system
applications, the 29EE010/29LE010/29VE010 signifi-
cantly improve performance and reliability, while lower-
ing power consumption, when compared with floppy disk
or EPROM approaches. The 29EE010/29LE010/
29VE010 improve flexibility while lowering the cost for
program, data, and configuration storage applications.
To meet high density, surface mount requirements, the
29EE010/29LE010/29VE010 are offered in 32-pin
TSOP and 32-lead PLCC packages. A 600-mil, 32-pin
PDIP package is also available. See Figures 1 and 2 for
pinouts.
Device Operation
The SST page mode EEPROM offers in-circuit electrical
write capability. The 29EE010/29LE010/29VE010 does
not require separate erase and program operations. The
internally timed write cycle executes both erase and
program transparently to the user. The 29EE010/
29LE010/29VE010 have industry standard optional
Software Data Protection, which SST recommends al-
ways to be enabled. The 29EE010/29LE010/29VE010
are compatible with industry standard EEPROM pinouts
and functionality.
Read
The Read operations of the 29EE010/29LE010/
29VE010 are controlled by CE# and OE#, both have to
be low for the system to obtain data from the outputs.
CE# is used for device selection. When CE# is high, the
