SIGNAL DESCRIPTIONS
See Figure 2, Logic Diagram, and Table 1, Signal
Names, for a brief overview of the signals connect-
ed to this device.
Address Inputs (A0-A21).
The Address Inputs
select the cells in the memory array to access dur-
ing Bus Read operations. During Bus Write opera-
tions they control the commands sent to the
Command Interface of the Program Controller.
Data Inputs/Outputs (DQ0-DQ7).
The Data In-
puts/Outputs output the data stored at the selected
address during a Bus Read operation. During Bus
Write operations they represent the command
sent to the Command Interface of the Program
Controller. When reading the Status Register they
report the status of the ongoing algorithm.
Data Inputs/Outputs (DQ8-DQ15).
The Data In-
puts/Outputs output the data stored at the selected
address during a Bus Read operation. During Bus
Write operations the Command Interface does not
use these bits. When reading the Status Register
these bits should be ignored.
Chip Enable (E).
The Chip Enable, E, activates
the memory, allowing Bus Read operations to be
performed. It also controls the Bus Write opera-
tions, when V
PP
is in the V
HH
range.
Output Enable (G).
The Output Enable, G, con-
trols the Bus Read operations of the memory. It
also allows Bus Write operations, when V
PP
is in
the V
HH
range.
V
CC
Supply Voltage.
The V
CC
Supply Voltage
supplies the power for Read operations.
A 0.1μF capacitor should be connected between
the V
CC
Supply Voltage pin and the V
SS
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 opera-
tions, I
CC3
.
V
PP
Program Supply Voltage.
V
PP
is both a
power supply and Write Protect pin. The two func-
tions are selected by the voltage range applied to
the pin.
When the V
PP
is in the V
HH
range (see Table 10,
DC Characteristic, for the relevant values) the Pro-
gram operation is enabled. During such opera-
tions the V
PP
must be stable in the V
HH
range.
If the V
PP
is kept under the V
HH
range, particularly
in the voltage range 0 to 3.6V, any Program oper-
ation is disabled or stopped.
Note that V
PP
must not be left floating or uncon-
nected as the device may become unreliable.
Vss Ground.
The V
SS
Ground is the reference
for all voltage measurements.
