PRODUCT DESCRIPTION

The GLS29EE010 is a 128K x8 CMOS Page-Write

EEPROMs manufactured with high-performance Super-

Flash technology. The split-gate cell design and thick-oxide

tunneling injector attain better reliability and manufacturabil-

ity compared with alternate approaches. The

GLS29EE010 write with a single power supply. Internal

Erase/Program is transparent to the user. The

GLS29EE010 conform to JEDEC standard pinouts for

byte-wide memories.

Featuring high performance Page-Write, the GLS29EE010

provides a typical Byte-Write time of 39 µsec. The entire

memory, i.e., 128 Kbyte, 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

GLS29EE010 has on-chip hardware and Software Data

Protection schemes. Designed, manufactured, and tested

for a wide spectrum of applications, the GLS29EE010 is

offered with a guaranteed Page-Write endurance of 10,000

cycles. Data retention is rated at greater than 100 years.

The GLS29EE010 is suited for applications that

require convenient and economical updating of pro-

gram, configuration, or data memory. For all system

applications, the GLS29EE010 significantly improves

performance and reliability, while lowering power con-

sumption. The GLS29EE010 improves flexibility while

lowering the cost for program, data, and configuration

storage applications.

To meet high density, surface mount requirements, the

GLS29EE010 is offered in 32-lead PLCC and 32-lead

TSOP packages. A 600-mil, 32-pin PDIP package is also

available. See Figures 2, 3, and 4 for pin assignments.

Device Operation

The Greenliant Page-Write EEPROM offers in-circuit elec-

trical write capability. The GLS29EE010 does not require

separate Erase and Program operations. The internally

timed Write cycle executes both erase and program trans-

parently to the user. The GLS29EE010 has industry stan-

dard optional Software Data Protection, which Greenliant

recommends always to be enabled. The GLS29EE010 is

compatible with industry standard EEPROM pinouts and

functionality.

Read

The Read operations of the GLS29EE010 is controlled 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 5).

Write

The Page-Write to the GLS29EE010 should always use

the JEDEC Standard Software Data Protection (SDP)

three-byte command sequence. The GLS29EE010 con-

tains the optional JEDEC approved Software Data Protec-

tion scheme. Greenliant 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.

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

GLS29EE010. 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 rising

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 6 and 7 for WE# and CE#

controlled Page-Write cycle timing diagrams and Figures

16 and 18 for flowcharts.

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

consists of a specific three-byte load sequence that allows

writing to the selected page and will leave the

GLS29EE010 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.

The Page-Write operation allows the loading of up to 128

bytes of data into the page buffer of the GLS29EE010

before the initiation of the internal Write cycle. During the

internal Write cycle, all the data in the page buffer is written

simultaneously into the memory array. Hence, the Page-

Write feature of GLS29EE010 allows the entire memory to

be written in as little as 5 seconds. During the internal Write

cycle, the host is free to perform additional 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 written to FFH.

See Figures 6 and 7 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

second byte into the page buffer within a byte-load cycle

time (TBLC) of 100 µs, the GLS29EE010 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.

Software Chip-Erase

The GLS29EE010 provides 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

Data Sheet

1 Mbit Page-Write EEPROM

GLS29EE010

Write cycle. During the Erase operation, the only valid read

is Toggle Bit. See Table 4 for the load sequence, Figure 11

for timing diagram, and Figure 20 for the flowchart.

Write Operation Status Detection

The GLS29EE010 provides two software means to detect

the completion of a Write cycle, in order to optimize the sys-

tem 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.

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.

Data# Polling (DQ7)

When the GLS29EE010 is in the internal Write cycle, any

attempt to read DQ7 of the last byte loaded during the byte-

load cycle will receive the complement of the true data.

Once the Write cycle is completed, DQ7 will show true

data. Note that even though DQ7 may have valid data

immediately following the completion of an internal Write

operation, the remaining data outputs may still be invalid:

valid data on the entire data bus will appear in subsequent

successive Read cycles after an interval of 1 µs. See Fig-

ure 8 for Data# Polling timing diagram and Figure 17 for a

flowchart.

Toggle Bit (DQ6)

During the internal Write cycle, any consecutive attempts to

read DQ6 will produce alternating ‘0’s and ‘1’s, 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 9 for Toggle Bit timing diagram and

Figure 17 for a flowchart. The initial read of the Toggle Bit

will typically be a “1”.

Data Protection

The GLS29EE010 provides both hardware and software

features to protect nonvolatile data from inadvertent writes.

Hardware Data Protection

Noise/Glitch Protection: A WE# or CE# pulse of less than 5

ns will not initiate a Write cycle.

VDD Power Up/Down Detection: The Write operation is

inhibited when VDD is less than 2.5V.

Write Inhibit Mode: Forcing OE# low, CE# high, or WE#

high will inhibit the Write operation. This prevents inadver-

tent writes during power-up or power-down.

Software Data Protection (SDP)

The GLS29EE010 provides the JEDEC approved optional

Software Data Protection scheme for all data alteration

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 inadver-

tent Write operations, e.g., during the system power-up or

power-down. The GLS29EE010 is shipped with the Soft-

ware Data Protection disabled.

The software protection scheme can be enabled by apply-

ing a three-byte sequence to the device, during a page-

load cycle (Figures 6 and 7). 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 6 and 7 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

10 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. Greenliant recommends Software Data Protec-

tion always be enabled. See Figure 18 for flowcharts.

The GLS29EE010 Software Data Protection is a global

command, protecting all pages in the entire memory array

once enabled. Therefore using SDP for a single Page-

Write will enable SDP for the entire array. Single pages by

themselves cannot be SDP enabled.

Single power supply reprogrammable nonvolatile memo-

ries may be unintentionally altered. Greenliant strongly rec-

ommends that Software Data Protection (SDP) always be

enabled. The GLS29EE010 should be programmed using

the SDP command sequence.

Product Identification

The Product Identification mode identifies the device

as the GLS29EE010 and manufacturer as Greenliant.

This mode is accessed via software. For details, see

Table 4, Figure 12 for the software ID entry and read

timing diagram and Figure 19, for the ID entry com-

mand sequence flowchart.

Product Identification Mode Exit

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 13 for timing waveform, and Figure 19 for a

flowchart.
