DEVICE BUS OPERATIONS
This section describes the requirements and use of
the device bus operations, which are initiated through
the internal command register. The command register
itself does not occupy any addressable memory loca-
tion. The register is a latch used to store the com-
mands, along with the address and data information
needed to execute the command. The contents of the
register serve as inputs to the internal state machine.
The state machine outputs dictate the function of the
device.
Table 1
lists the device bus operations, the in-
puts and control levels they require, and the resulting
output. The following subsections describe each of
these operations in further detail.

Notes:
1. Addresses are A22:A0. Sector addresses are A22:A16.
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the
“Sector Group

section.

ordered.)

VersatileIO
TM
(V
IO
) Control
The VersatileIO (V
IO
) control allows the host system
to set the voltage levels that the device generates and
tolerates on CE# and DQ I/Os to the same voltage
level that is asserted on V
IO
. V
IO
is available in two
configurations (1.8–2.9 V and 3.0–5.0 V) for operation
in various system environments.
For example, a V
I/O
of 4.5–5.0 volts allows for I/O at
the 5 volt level, driving and receiving signals to and
from other 5 V devices on the same data bus.
Requirements for Reading Array Data
To read array data from the outputs, the system must
drive the CE# and OE# pins to V
IL
. CE# is the power
control and selects the device. OE# is the output con-
trol and gates array data to the output pins. WE#
should remain at V
IH
.
The internal state machine is set for reading array data
upon device power-up, or after a hardware reset. This
ensures that no spurious alteration of the memory
content occurs during the power transition. No com-
mand is necessary in this mode to obtain array data.
Standard microprocessor read cycles that assert valid
addresses on the device address inputs produce valid
data on the device data outputs. The device remains
