PRODUCT DESCRIPTION  
The SST29EE/LE/VE020 are 256K x8 CMOS Page-Write  
EEPROM manufactured with SST’s proprietary, high per-  
formance CMOS SuperFlash technology. The split-gate  
cell design and thick oxide tunneling injector attain better  
reliability and manufacturability compared with alternate  
approaches. The SST29EE/LE/VE020 write with a single  
power supply. Internal Erase/Program is transparent to the  
user. The SST29EE/LE/VE020 conform to JEDEC stan-  
dard pinouts for byte-wide memories.  
The SST29EE/LE/VE020 are suited for applications that  
require convenient and economical updating of program,  
configuration, or data memory. For all system applications,  
the SST29EE/LE/VE020 significantly improve performance  
and reliability, while lowering power consumption. The  
SST29EE/LE/VE020 improve flexibility while lowering the  
cost for program, data, and configuration storage applica-  
tions.  
To meet high density, surface mount requirements, the  
SST29EE/LE/VE020 are offered in 32-lead PLCC and 32-  
lead TSOP packages. A 600-mil, 32-pin PDIP package is  
also available. See Figures 1, 2, and 3 for pinouts.  
Featuring high performance Page-Write, the SST29EE/LE/  
VE020 provide a typical Byte-Write time of 39 µsec. The  
entire memory, i.e., 256 KBytes, can be written page-by-  
page in as little as 10 seconds, when using interface fea-  
tures such as Toggle Bit or Data# Polling to indicate the  
completion of a Write cycle. To protect against inadvertent  
write, the SST29EE/LE/VE020 have on-chip hardware and  
Software Data Protection schemes. Designed, manufac-  
tured, and tested for a wide spectrum of applications, the  
SST29EE/LE/VE020 are offered with a guaranteed Page-  
Write endurance of 10,000 cycles. Data retention is rated at  
greater than 100 years.  
Device Operation  
The SST Page-Mode EEPROM offers in-circuit electrical  
write capability. The SST29EE/LE/VE020 does not require  
separate Erase and Program operations. The internally  
timed Write cycle executes both erase and program trans-  
parently to the user. The SST29EE/LE/VE020 have indus-  
try standard optional Software Data Protection, which SST  
recommends always to be enabled. The SST29EE/LE/  
VE020 are compatible with industry standard EEPROM  
pinouts and functionality.
