PRODUCT DESCRIPTION
The SST29EE/LE/VE512 are 64K 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/LE/VE512 write
with a single power supply. Internal Erase/Program is
transparent to the user. The SST29EE/LE/VE512 con-
form to JEDEC standard pinouts for byte-wide memories.
The SST29EE/LE/VE512 are suited for applications that
require convenient and economical updating of program,
configuration, or data memory. For all system applica-
tions, the SST29EE/LE/VE512 significantly improve per-
formance and reliability, while lowering power
consumption. The SST29EE/LE/VE512 improve flexibil-
ity while lowering the cost for program, data, and configu-
ration storage applications.
To meet high density, surface mount requirements, the
SST29EE/LE/VE512 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/VE512 provide a typical Byte-Write time of 39 µsec.
The entire memory, i.e., 64 KBytes, 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 inad-
vertent write, the SST29EE/LE/VE512 have on-chip
hardware and Software Data Protection schemes.
Designed, manufactured, and tested for a wide spectrum
of applications, the SST29EE/LE/VE512 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/VE512 do 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/VE512 have indus-
try standard optional Software Data Protection, which SST
recommends always to be enabled. The SST29EE/LE/
VE512 are compatible with industry standard EEPROM
pinouts and functionality.

512 Kbit Page-Mode EEPROM
SST29EE512 / SST29LE512 / SST29VE512
Data Sheet
consists of a specific three byte-load sequence that allows
writing to the selected page and will leave the SST29EE/
LE/VE512 protected at the end of the Page-Write. The
page load cycle consists of loading 1 to 128 Bytes of data
into the page buffer. The internal Write cycle consists of the
TBLCO time-out and the write timer operation. During the
Write operation, the only valid reads are Data# Polling and
Toggle Bit.
Read
The Read operations of the SST29EE/LE/VE512 are con-
trolled 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 chip is deselected and
only standby power is consumed. OE# is the output control
and is used to gate data from the output pins. The data bus
is in high impedance state when either CE# or OE# is high.
Refer to the read cycle timing diagram for further details
(Figure 4).
The Page-Write operation allows the loading of up to 128
Bytes of data into the page buffer of the SST29EE/LE/
VE512 before the initiation of the internal Write cycle. Dur-
ing the internal Write cycle, all the data in the page buffer is
written simultaneously into the memory array. Hence, the
Page-Write feature of SST29EE/LE/VE512 allows the
entire memory to be written in as little as 2.5 seconds. Dur-
ing the internal Write cycle, the host is free to perform addi-
tional tasks, such as to fetch data from other locations in
the system to set up the write to the next page. In each
Page-Write operation, all the bytes that are loaded into the
page buffer must have the same page address, i.e. A7
through A16. Any byte not loaded with user data will be writ-
ten to FFH.
Write
The Page-Write to the SST29EE/LE/VE512 should always
use the JEDEC Standard Software Data Protection (SDP)
three-byte command sequence. The SST29EE/LE/VE512
contain the optional JEDEC approved Software Data Pro-
tection scheme. SST recommends that SDP always be
enabled, thus, the description of the Write operations will
be given using the SDP enabled format. The three-byte
SDP Enable and SDP Write commands are identical;
therefore, any time a SDP Write command is issued,
Software Data Protection is automatically assured. The
first time the three-byte SDP command is given, the device
becomes SDP enabled. Subsequent issuance of the same
command bypasses the data protection for the page being
written. At the end of the desired Page-Write, the entire
device remains protected. For additional descriptions,
please see the application notes The Proper Use of
JEDEC Standard Software Data Protection and Protecting
Against Unintentional Writes When Using Single Power
Supply Flash Memories.
See Figures 5 and 6 for the Page-Write cycle timing dia-
grams. If after the completion of the three-byte SDP load
sequence or the initial byte-load cycle, the host loads a sec-
ond byte into the page buffer within a byte-load cycle time
(TBLC) of 100 µs, the SST29EE/LE/VE512 will stay in the
page load cycle. Additional bytes are then loaded consecu-
tively. The page load cycle will be terminated if no addi-
tional byte is loaded into the page buffer within 200 µs
(TBLCO) from the last byte-load cycle, i.e., no subsequent
WE# or CE# high-to-low transition after the last rising edge
of WE# or CE#. Data in the page buffer can be changed by
a subsequent byte-load cycle. The page load period can
continue indefinitely, as long as the host continues to load
the device within the byte-load cycle time of 100 µs. The
page to be loaded is determined by the page address of
the last byte loaded.
The Write operation consists of three steps. Step 1 is the
three-byte load sequence for Software Data Protection.
Step 2 is the byte-load cycle to a page buffer of the
SST29EE/LE/VE512. Steps 1 and 2 use the same timing
for both operations. Step 3 is an internally controlled write
cycle for writing the data loaded in the page buffer into the
memory array for nonvolatile storage. During both the SDP
three-byte load sequence and the byte-load cycle, the
addresses are latched by the falling edge of either CE# or
WE#, whichever occurs last. The data is latched by the ris-
ing edge of either CE# or WE#, whichever occurs first. The
internal write cycle is initiated by the TBLCO timer after the
rising edge of WE# or CE#, whichever occurs first. The
Write cycle, once initiated, will continue to completion, typi-
cally within 5 ms. See Figures 5 and 6 for WE# and CE#
controlled Page-Write cycle timing diagrams and Figures
15 and 17 for flowcharts.
Software Chip-Erase
The SST29EE/LE/VE512 provide a Chip-Erase operation,
which allows the user to simultaneously clear the entire
memory array to the “1” state. This is useful when the entire
device must be quickly erased.
The Software Chip-Erase operation is initiated by using a
specific six-byte load sequence. After the load sequence,
the device enters into an internally timed cycle similar to the
Write cycle. During the Erase operation, the only valid read
is Toggle Bit. See Table 4 for the load sequence, Figure 10
for timing diagram, and Figure 19 for the flowchart.
The Write operation has three functional cycles: the Soft-
ware Data Protection load sequence, the page load cycle,
and the internal Write cycle. The Software Data Protection

Data Sheet
Write Inhibit Mode: Forcing OE# low, CE# high, or WE#
high will inhibit the Write operation. This prevents inadvert-
ent writes during power-up or power-down.
Write Operation Status Detection
The SST29EE/LE/VE512 provide two software means to
detect the completion of a Write cycle, in order to optimize
the system write cycle time. The software detection
includes two status bits: Data# Polling (DQ7) and Toggle Bit
(DQ6). The end of write detection mode is enabled after the
rising WE# or CE# whichever occurs first, which initiates
the internal Write cycle.
Software Data Protection (SDP)
The SST29EE/LE/VE512 provide the JEDEC approved
optional Software Data Protection scheme for all data alter-
ation operations, i.e., Write and Chip-Erase. With this
scheme, any Write operation requires the inclusion of a
series of three byte-load operations to precede the data
loading operation. The three byte-load sequence is used to
initiate the Write cycle, providing optimal protection from
inadvertent write operations, e.g., during the system power-
up or power-down. The SST29EE/LE/VE512 are shipped
with the Software Data Protection disabled.
The actual completion of the nonvolatile write is asynchro-
nous with the system; therefore, either a Data# Polling or
Toggle Bit read may be simultaneous with the completion
of the Write cycle. If this occurs, the system may possibly
get an erroneous result, i.e., valid data may appear to con-
flict with either DQ7 or DQ6. In order to prevent spurious
rejection, if an erroneous result occurs, the software routine
should include a loop to read the accessed location an
additional two (2) times. If both reads are valid, then the
device has completed the Write cycle, otherwise the rejec-
tion is valid.
The software protection scheme can be enabled by apply-
ing a three-byte sequence to the device, during a page-
load cycle (Figures 5 and 6). The device will then be auto-
matically set into the data protect mode. Any subsequent
write operation will require the preceding three-byte
sequence. See Table 4 for the specific software command
codes and Figures 5 and 6 for the timing diagrams. To set
the device into the unprotected mode, a six-byte sequence
is required. See Table 4 for the specific codes and Figure 9
for the timing diagram. If a write is attempted while SDP is
enabled the device will be in a non-accessible state for ~
300 µs. SST recommends Software Data Protection
always be enabled. See Figure 17 for flowcharts.
Data# Polling (DQ7)
When the SST29EE/LE/VE512 are in the internal Write
cycle, any attempt to read DQ7 of the last byte loaded dur-
ing the byte-load cycle will receive the complement of the
true data. Once the Write cycle is completed, DQ7 will
show true data. The device is then ready for the next opera-
tion. See Figure 7 for Data# Polling timing diagram and Fig-
ure 16 for a flowchart.
The SST29EE/LE/VE512 Software Data Protection is a
global command, protecting (or unprotecting) all pages in
the entire memory array once enabled (or disabled). There-
fore using SDP for a single Page-Write will enable SDP for
the entire array. Single pages by themselves cannot be
SDP enabled or disabled, although the page addressed
during the SDP write will be written.
Toggle Bit (DQ6)
During the internal Write cycle, any consecutive attempts to
read DQ6 will produce alternating 0s and 1s, i.e., toggling
between 0 and 1. When the Write cycle is completed, the
toggling will stop. The device is then ready for the next
operation. See Figure 8 for Toggle Bit timing diagram and
Figure 16 for a flowchart. The initial read of the Toggle Bit
will typically be a “1”.
Single power supply reprogrammable nonvolatile memo-
ries may be unintentionally altered. SST strongly recom-
mends that Software Data Protection (SDP) always be
enabled. The SST29EE/LE/VE512 should be programmed
using the SDP command sequence. SST recommends the
SDP Disable Command Sequence not be issued to the
device prior to writing.
Data Protection
The SST29EE/LE/VE512 provide both hardware and soft-
ware features to protect nonvolatile data from inadvertent
writes.

information on using SDP:

Product Identification
Product Identification Mode Exit
The product identification mode identifies the device as the
SST29EE/LE/VE512 and manufacturer as SST. This mode
is accessed via software. For details, see Table 4, Figure
11 for the software ID entry, and read timing diagram and
Figure 18 for the ID entry command sequence flowchart.
In order to return to the standard read mode, the Software
Product Identification mode must be exited. Exiting is
accomplished by issuing the Software ID Exit (reset) opera-
tion, which returns the device to the Read operation. The
Reset operation may also be used to reset the device to the
Read mode after an inadvertent transient condition that
apparently causes the device to behave abnormally, e.g.,
not read correctly. See Table 4 for software command
codes, Figure 12 for timing waveform, and Figure 18 for a
flowchart.
