updating of program, configuration, or data memory. For

all system applications, the SST29EE010A/29LE010A/

29VE010A significantly improve performance and reli-

ability, while lowering power consumption. The

SST29EE010A/29LE010A/29VE010A improve flexibil-

ity while lowering the cost for program, data, and configu-

ration storage applications.

To meet high density, surface mount requirements, the

SST29EE010A/29LE010A/29VE010A 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 SST29EE010A/29LE010A/

29VE010A does not require separate Erase and

Program operations. The internally timed write cycle

executes both erase and program transparently to the

user. The SST29EE010A/29LE010A/29VE010A have

industry standard Software Data Protection. The

SST29EE010A/29LE010A/29VE010A are compatible

with industry standard EEPROM pinouts and

functionality.

Read

The Read operations of the SST29EE010A/29LE010A/

29VE010A are controlled by CE# and OE#, both have to

be low for the system to obtain data from the outputs.

PRODUCT DESCRIPTION

The SST29EE010A/29LE010A/29VE010A are 128K x 8

CMOS Page Write EEPROMs manufactured with SST’s

proprietary, high performance CMOS SuperFlash tech-

nology. The split-gate cell design and thick oxide tunnel-

ing injector attain better reliability and manufacturability

compared with alternate approaches. The

SST29EE010A/29LE010A/29VE010A write with a

single power supply. Internal Erase/Program is transpar-

ent to the user. The SST29EE010A/29LE010A/

29VE010A conform to JEDEC standard pinouts for byte-

wide memories.

Featuring high performance page write, the

SST29EE010A/29LE010A/29VE010A provide a typical

byte-write time of 39 µsec. The entire memory, i.e., 128

KBytes, 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

SST29EE010A/29LE010A/29VE010A have on-chip

hardware and software data protection schemes. De-

signed, manufactured, and tested for a wide spectrum of

applications, the SST29EE010A/29LE010A/29VE010A

are offered with a guaranteed page write endurance of

cycles. Data retention is rated at greater than 100

years.

The SST29EE010A/29LE010A/29VE010A are suited

for applications that require convenient and economical
