STS is not Low during a reset unless the reset was
applied when the Program/Erase controller was
active
Program/Erase Enable (VPEN). The
Program/
Erase Enable input, VPEN, is used to protect all
blocks, preventing Program and Erase operations
from affecting their data.
Program/Erase Enable must be kept High during
all Program/Erase Controller operations, other-
wise the operations is not guaranteed to succeed
and data may become corrupt.
VDD Supply Voltage. The Supply Voltage, VDD,
is the core power supply. All internal circuits draw
their current from the VDD pin, including the Pro-
gram/Erase Controller.
A 0.1
F capacitor should be connected between
the Supply Voltage, VDD, and the Ground, VSS,to
decouple the current surges from the power sup-
ply. The PCB track widths must be sufficient to
carry the currents required during all operations of
the parts, see Table 14, DC Characteristics, for
maximum current supply requirements.
Input/Output Supply Voltage (VDDQ). The
In-
put/Output Supply Voltage, VDDQ, is the input/out-
put buffer power supply. All input and output pins
and voltage references are powered and mea-
sured relative to the Input/Output Supply Voltage
pin, VDDQ.
The Input/Output Supply Voltage, VDDQ, must al-
ways be equal or less than the VDD Supply Volt-
age, including during Power-Up.
A 0.1
F capacitor should be connected between
the Input/Output Supply Voltage, VDDQ, and the
Ground, VSSQ, to decouple the current surges
from the power supply. If VDDQ and VDD are con-
nected together then only one decoupling capaci-
tor is required.
Ground (VSS). Ground, VSS, is the reference for
all core power supply voltages.
Ground (VSSQ). Ground, VSSQ, is the reference
for input/output voltage measurements. It is es-
sential to connect VSS and VSSQ to the same
ground.
