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. CE# can be replaced with CE2# when referring to the second die in the package. CE# and CE2# must not both be driven at
the same time.
2. Addresses are A22:A0. Sector addresses are A22:A16.

4. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the “Sector Group
Protection and Unprotection” section.
5. All sectors are unprotected when shipped from the factory.
VersatileIO
(V
IO
) Control
The VersatileIO (V
IO
) control allows the host system to
set the voltage levels that the device generates at its
data outputs and the voltages tolerated at its data in-
puts to the same voltage level that is asserted on V
IO
.
This allows the device to operate in a 3 V or 5 V sys-
tem environment as required. For voltage levels below
3 V, contact an AMD representative for more informa-
tion.
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 CE# or CE2# and OE# to V
IL
. CE# or CE2# is the
power control and selects the device. OE# is the out-
put control and gates array data to the outputs. 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
