PRODUCT DESCRIPTION

The SST29EE512 is a 64K 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 SST29EE512 writes with a single

power supply. Internal Erase/Program is transparent to

the user. The SST29EE512 conforms to JEDEC stan-

dard pin assignments for byte-wide memories.

Featuring

high

performance

Page-Write,

the

SST29EE512 provides a typical Byte-Write time of 39

µsec. The entire memory, i.e., 64 KByte, can be written

page-by-page in as little as 2.5 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 SST29EE512 have on-chip

hardware and Software Data Protection schemes.

Designed, manufactured, and tested for a wide spectrum

of applications, the SST29EE512 is offered with a guar-

anteed Page-Write endurance of 10,000 cycles. Data

retention is rated at greater than 100 years.

The SST29EE512 is suited for applications that require

convenient and economical updating of program, config-

uration, or data memory. For all system applications, the

SST29EE512 significantly improves performance and

reliability, while lowering power consumption. The

SST29EE512 improves flexibility while lowering the cost

for program, data, and configuration storage applications.

To meet high density, surface mount requirements, the

SST29EE512 is 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 SST29EE512 does not require sepa-

rate Erase and Program operations. The internally timed

Write cycle executes both erase and program transparently

to the user. The SST29EE512 has industry standard

optional Software Data Protection, which SST recom-

mends always to be enabled. The SST29EE512 is com-

patible with industry standard EEPROM pinouts and

functionality.
