pedance during Read mode, Auto Select mode
and Erase Suspend mode.
After a Hardware Reset, Bus Read and Bus Write
operations cannot begin until Ready/Busy be-
comes high-impedance. See
Table 15.
and
Figure
12., Reset/Block Temporary Unprotect AC Wave-
forms
, for more details.
The use of an open-drain output allows the Ready/
Busy pins from several memories to be connected
to a single pull-up resistor. A Low will then indicate
that one, or more, of the memories is busy.
Byte/Word Organization Select (BYTE).
The
Byte/Word Organization Select pin is used to
switch between the x8 and x16 Bus modes of the
memory. When Byte/Word Organization Select is
Low, V
IL
, the memory is in x8 mode, when it is
High, V
IH
, the memory is in x16 mode.

Program and Erase).
pro-
The Command Interface is disabled when the V
CC
Supply Voltage is less than the Lockout Voltage,
V
LKO
. This prevents Bus Write operations from ac-
cidentally damaging the data during power up,
power down and power surges. If the Program/
Erase Controller is programming or erasing during
this time then the operation aborts and the memo-
ry contents being altered will be invalid.
A 0.1μF capacitor should be connected between
the V

Supply Voltage pin and the V

Ground
pin to decouple the current surges from the power
supply. The PCB track widths must be sufficient to
carry the currents required during Program and
Erase operations, I

is the reference for all voltage
measurements. The device features two V

pins
which must be both connected to the system
