their current from the VDD pin, including the Pro-

gram/Erase Controller.

A 0.1µF 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 16, 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 0.1µF 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.
