PRODUCT DESCRIPTION
The SST29EE/VE010 are 128K x8 CMOS Page-Write
EEPROMs manufactured with SST’s proprietary, 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 SST29EE/VE010 write with a single
power supply. Internal Erase/Program is transparent to the
user. The SST29EE/VE010 conform to JEDEC standard
pinouts for byte-wide memories.
Featuring high performance Page-Write, the SST29EE/
VE010 provide a typical Byte-Write time of 39 µsec. The
entire memory, i.e., 128 Kbyte, can be written page-bypage 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 SST29EE/VE010 have on-chip hardware and Software
Data Protection schemes. Designed, manufactured, and
tested for a wide spectrum of applications, the SST29EE/
VE010 are offered with a guaranteed Page-Write endurance of 10,000 cycles. Data retention is rated at greater
than 100 years.

The SST29EE/VE010 are suited for applications that
require convenient and economical updating of program, configuration, or data memory. For all system
applications, the SST29EE/VE010 significantly
improve performance and reliability, while lowering
power consumption. The SST29EE/VE010 improve
flexibility while lowering the cost for program, data, and
configuration storage applications.
To meet high density, surface mount requirements, the
SST29EE/VE010 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 pin assignments.
Device Operation
The SST Page-Write EEPROM offers in-circuit electrical
write capability. The SST29EE/VE010 does not require
separate Erase and Program operations. The internally
timed Write cycle executes both erase and program transparently to the user. The SST29EE/VE010 have industry
standard optional Software Data Protection, which SST
recommends always to be enabled. The SST29EE/VE010
are compatible with industry standard EEPROM pinouts
and functionality.
