DEVICE OPERATION
Read
Write Operation Status Bits
The X28C010 provides the user two write operation
status bits.These can be used to optimize a system write
cycle time. The status bits are mapped onto the I/O bus
as shown in Figure 1.
Read operations are initiated by both OE and CE LOW.
The read operation is terminated by either CE or OE
returning HIGH. This two line control architecture
eliminates bus contention in a system environment. The
data bus will be in a high impedance state when either
OE or CE is HIGH.

Write
Write operations are initiated when both CE and WE are
LOW and OE is HIGH.The X28C010 supports both a
CE and WE controlled write cycle. That is, the address is
latched by the falling edge of either CE or WE, whichever
occurs last. Similarly, the data is latched internally by the
rising edge of either CE or WE, whichever occurs first. A
byte write operation, once initiated, will automatically
continue to completion, typically within 5ms.

TOGGLE BIT
DATA POLLING
DATA Polling (I/O7)
The X28C010 features DATA Polling as a method to
indicate to the host system that the byte write or page
write cycle has completed. DATA Polling allows a simple
bit test operation to determine the status of the X28C010,
eliminating additional interrupt inputs or external
hardware. During the internal programming cycle, any
attempt to read the last byte written will produce the
complement of that data on I/O7 (i.e., write data = 0xxx
xxxx, read data = 1xxx xxxx). Once the programming
cycle is complete, I/O7 will reflect true data. Note: If the
X28C010 is in the protected state and an illegal write
operation is attempted DATA Polling will not operate.
Page Write Operation
The page write feature of the X28C010 allows the entire
memory to be written in 5 seconds. Page write allows two
to two hundred fifty-six bytes of data to be consecutively
written to the X28C010 prior to the commencement of
the internal programming cycle. The host can fetch data
from another device within the system during a page
write operation (change the source address), but the
page address (A8 through A16) for each subsequent valid
write cycle to the part during this operation must be the
same as the initial page address.
Toggle Bit (I/O6)
The X28C010 also provides another method for
determining when the internal write cycle is complete.
During the internal programming cycle, I/O6 will toggle
from HIGH to LOW and LOW to HIGH on subsequent
attempts to read the device. When the internal cycle is
complete the toggling will cease and the device will be
accessible for additional read or write operations.
The page write mode can be initiated during any write
operation. Following the initial byte write cycle, the host
can write an additional one to two hundred fifty six bytes
in the same manner as the first byte was written. Each
successive byte load cycle, started by the WE HIGH to
LOW transition, must begin within 100µs of the falling
edge of the preceding WE. If a subsequent WE HIGH to
LOW transition is not detected within 100µs, the internal
automatic programming cycle will commence. There is
no page write window limitation. Effectively the page
write window is infinitely wide, so long as the host
continues to access the device within the byte load cycle
time of 100µs.

The Toggle Bit can eliminate the software housekeeping
chore of saving and fetching the last address and data

This can be especially helpful in an array comprised of
multiple X28C010 memories that is frequently updated.
Toggle Bit Polling can also provide a method for status
checking in multiprocessor applications. The timing
diagram in Figure 4 illustrates the sequence of events on

HARDWARE DATA PROTECTION
The X28C010 can be automatically protected during
power-up and power-down without the need for external
circuits by employing the software data protection
feature. The internal software data protection circuit is
enabled after the first write operation utilizing the
software algorithm. This circuit is nonvolatile and will
remain set for the life of the device unless the reset
command is issued.
The X28C010 provides three hardware features that
protect nonvolatile data from inadvertent writes.
• Noise Protection—A WE pulse less than 10ns will not
initiate a write cycle.
• Default VCC Sense—All functions are inhibited when
VCC is £3.5V.
• Write inhibit—Holding either OE LOW, WE HIGH, or
CE HIGH will prevent an inadvertent write cycle during
power-up and power-down, maintaining data integrity.
Once the software protection is enabled, the X28C010 is
also protected from inadvertent and accidental writes in
the powered-up state. That is, the software algorithm
must be issued prior to writing additional data to the
device.
SOFTWARE DATA PROTECTION
The X28C010 offers a software controlled data protection
feature. The X28C010 is shipped from Xicor with the
software data protection NOT ENABLED: that is the
device will be in the standard operating mode. In this
mode data should be protected during power-up/-down
operations through the use of external circuits. The host
would then have open read and write access of the
device once VCC was stable.
SOFTWARE ALGORITHM
Selecting the software data protection mode requires the
host system to precede data write operations by a series
of three write operations to three specific addresses.
Refer to Figures 6 and 7 for the sequence.The three byte
sequence opens the page write window enabling the
host to write from one to two hundred fifty-six bytes of
data. Once the page load cycle has been completed, the
device will automatically be returned to the data
protected state.

Regardless of whether the device has previously been

algorithm is used and data has been written, the
X28C010 will automatically disable further writes unless
another command is issued to cancel it. If no further
commands are issued the X28C010 will be write
protected during power-down and after any subsequent
power-up. The state of A15 and A16 while executing the
algorithm is don’t care.

SYSTEM CONSIDERATIONS
the output capacitive loading of the I/Os. Therefore, the
larger the array sharing a common bus, the larger the
transient spikes. The voltage peaks associated with the
current transients can be suppressed by the proper
selection and placement of decoupling capacitors. As a
minimum, it is recommended that a 0.1µF high frequency
ceramic capacitor be used between VCC and VSS at each
device. Depending on the size of the array, the value of
the capacitor may have to be larger.
Because the X28C010 is frequently used in large
memory arrays it is provided with a two line control
architecture for both read and write operations. Proper
usage can provide the lowest possible power dissipation
and eliminate the possibility of contention where multiple
I/O pins share the same bus.
To gain the most benefit it is recommended that CE be
decoded from the address bus and be used as the
primary device selection input. Both OE and WE would
then be common among all devices in the array. For a
read operation this assures that all deselected devices
are in their standby mode and that only the selected
device(s) is outputting data on the bus.
In addition, it is recommended that a 4.7µF electrolytic
bulk capacitor be placed between VCC and VSS for each
eight devices employed in the array.This bulk capacitor is
employed to overcome the voltage drop caused by the
inductive effects of the PC board traces.
Because the X28C010 has two power modes, standby
and active, proper decoupling of the memory array is of
prime concern. Enabling CE will cause transient current
spikes. The magnitude of these spikes is dependent on

writes to an unknown address could occur.
Notes: (5) Between successive byte writes within a page write operation, OE can be strobed LOW: e.g. this can be done with CE and WE HIGH to
fetch data from another memory device within the system for the next write; or with WE HIGH and CE LOW effectively performing a poll-
ing operation.
(6) The timings shown above are unique to page write operations. Individual byte load operations within the page write must conform to
either the CE or WE controlled write cycle timing.
