DEVICE OPERATION
Read
Write Operation Status Bits
The X28HC64 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 X28HC64 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 comple-
tion, typically within 2ms.

DATA Polling
DATA Polling (I/O )
7
The X28HC64 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 sim-
ple bit test operation to determine the status of the
X28HC64, eliminating additional interrupt inputs or
external hardware. During the internal programming
cycle, any attempt to read the last byte written will pro-
Page Write Operation
The page write feature of the X28HC64 allows the
entire memory to be written in 0.25 seconds. Page write
allows two to sixty-four bytes of data to be consecu-
tively written to the X28HC64 prior to the commence-
ment 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),
duce the complement of that data on I/O (i.e. write
data = 0xxx xxxx, read data = 1xxx xxxx). Once the
7
programming cycle is complete, I/O will reflect true data.

but the page address (A through A ) for each subse-
quent valid write cycle to the part during this operation
must be the same as the initial page address.

Toggle Bit (I/O )

The X28HC64 also provides another method for deter-
mining when the internal write cycle is complete. Dur-
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 sixty-three bytes in
the same manner. 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 program-
ming cycle will commence. There is no page write win-
dow 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.
ing the internal programming cycle I/O will toggle
6
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 Toggle Bit can eliminate the chore of saving and

DATA Polling. This can be especially helpful in an array
comprised of multiple X28HC64 memories that is fre-
quently updated. Toggle Bit Polling can also provide a
method for status checking in multiprocessor applica-
tions. The timing diagram in Figure 4 illustrates the
sequence of events on the bus. The software flow dia-

HARDWARE DATA PROTECTION
The X28HC64 can be automatically protected during
power-up and power-down without the need for exter-
nal circuits by employing the software data protection
feature. The internal software data protection circuit is
enabled after the first write operation utilizing the soft-
ware algorithm. This circuit is nonvolatile and will
remain set for the life of the device, unless the reset
command is issued.
The X28HC64 provides two hardware features that
protect nonvolatile data from inadvertent writes.
– Default V Sense—All write functions are inhibited
CC
when V is 3V typically.
CC
– Write Inhibit—Holding either OE LOW, WE HIGH, or
CE HIGH will prevent an inadvertent write cycle dur-
ing power-up and power-down, maintaining data
integrity.
Once the software protection is enabled, the X28HC64
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 X28HC64 offers a software controlled data pro-
tection feature. The X28HC64 is shipped from Intersil
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 cir-
cuits. The host would then have open read and write
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 Figure 6 and 7 for the sequence.
The three-byte sequence opens the page write window,
enabling the host to write from one to sixty-four bytes
of data. Once the page load cycle has been com-
pleted, the device will automatically be returned to the
data protected state.

and after any subsequent power-up.

SYSTEM CONSIDERATIONS
Because the X28HC64 has two power modes,
standby and active, proper decoupling of the memory
array is of prime concern. Enabling CE will cause tran-
sient current spikes. The magnitude of these spikes is
dependent on 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 sup-
pressed by the proper selection and placement of
decoupling capacitors. As a minimum, it is recom-
mended that a 0.1µF high frequency ceramic capacitor
Because the X28HC64 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 dissipa-
tion, 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/are outputting data on the bus.

Depending on the size of the array, the value of the

Notes: (5) tWC is the minimum cycle time to be allowed from the system perspective unless polling techniques are used. It is the maximum time
the device requires to automatically complete the internal write operation.
(6) tWPH and tDW are periodically sampled and not 100% tested.

*For each successive write within the page write operation, A6–A12 should be the same or
writes to an unknown address could occur.
Notes: (7) 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
polling operation.
(8) 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.
