AC WRITE CHARACTERISTICS
(VCC = 5.0V, VSS = 0V, TA = -55°C to +125°C)
WRITE
A write cycle is initiated when OE is high and a low pulse is on WE
or CS with CS or WE low. The address is latched on the falling
edge of CS or WE whichever occurs last. The data is latched by
the rising edge of CS or WE, whichever occurs first. A byte write
operation will automatically continue to completion.

WRITE CYCLE TIMING

Figures 5 and 6 show the write cycle timing relationships. A
write cycle begins with address application, write enable and
chip select. Chip select is accomplished by placing the CS line
low. Write enable consists of setting the WE line low. The
write cycle begins when the last of either CS or WE goes low.

The WE line transition from high to low also initiates an
internal 150 µsec delay timer to permit page mode operation.
Each subsequent WE transition from high to low that occurs
before the completion of the 150 µsec time out will restart the
timer from zero. The operation of the timer is the same as a
retriggerable one-shot.

READ
The WE128K32-XXX stores data at the memory location
determined by the address pins. When CS and OE are low and
WE is high, this data is present on the outputs. When CS and
OE are high, the outputs are in a high impedance state. This
two line control prevents bus contention.

WE128K32-XXX
DATA POLLING
The WE128K32-XXX offers a data polling feature which allows
a faster method of writing to the device. Figure 8 shows the
timing diagram for this function. During a byte or page write
cycle, an attempted read of the last byte written will result in
the complement of the written data on D7 (for each chip.) Once
the write cycle has been completed, true data is valid on all
outputs and the next cycle may begin. Data polling may begin
at any time during the write cycle.

PAGE WRITE CHARACTERISTICS
(VCC = 5.0V, VSS = 0V, TA = -55°C to +125°C)
PAGE WRITE OPERATION
The WE128K32-XXX has a page write operation that allows one to
128 bytes of data to be written into the device and consecutively
loads during the internal programming period. Successive bytes
may be loaded in the same manner after the first data byte has
been loaded. An internal timer begins a time out operation at each
write cycle. If another write cycle is completed within 150µs or
less, a new time out period begins. Each write cycle restarts the
delay period. The write cycles can be continued as long as the
interval is less than the time out period.

The usual procedure is to increment the least significant
address lines from A0 through A6 at each write cycle. In this
manner a page of up to 128 bytes can be loaded in to the
EEPROM in a burst mode before beginning the relatively long
interval programming cycle.

Write Pulse Width High
1. Page address must remain valid for duration of write cycle.
After the 150µs time out is completed, the EEPROM begins an
internal write cycle. During this cycle the entire page of bytes
will be written at the same time. The internal programming
cycle is the same regardless of the number of bytes accessed.

SOFTWARE DATA PROTECTION
FIG. 11
A software write protection feature may be enabled or disabled
by the user. When shipped by White Microelectronics, the WE-
128K32-XXX has the feature disabled. Write access to the
device is unrestricted.
SOFTWARE DATA PROTECTION
(1)
DISABLE ALGORITHM
To enable software write protection, the user writes three
access code bytes to three special internal locations. Once
write protection has been enabled, each write to the EEPROM
must use the same three byte write sequence to permit writing.
After setting software data protection, any attempt to write to
the device without the three-byte command sequence will start
the internal write timers. No data will be written to the device,
however, for the duration of tWC. The write protection feature
can be disabled by a six byte write sequence of specific data to
specific locations. Power transitions will not reset the
software write protection.

Each 128K byte block of the EEPROM has independent write
protection. One or more blocks may be enabled and the rest
disabled in any combination. The software write protection
guards against inadvertent writes during power transitions, or
unauthorized modification using a PROM programmer.

b) VCC sense
While below 3.8V typical write cycles are inhibited.
c) Write inhibiting
Holding OE low and either CS or WE high inhibits write

d) Noise filter
Pulses of <8ns (typ) on WE or CS will not initiate a write
cycle.
NOTES:
1. Data Format: D7 - D0 (Hex);
Address Format: A16 - A0 (Hex).
2. Write Protect state will be activated at end of write even if no other
data is loaded.
3. Write Protect state will be deactivated at end of write period even if
no other data is loaded.
4. 1 to 128 bytes of data may be loaded.
