Advanced Information

PRELIMINARY

POWER AND GROUND PINS

VCCA, VCCD (Voltage Inputs)

To minimize noise, the analog and digital circuits in the Winbond I5216 device use separate power

busses. These +3 V busses lead to separate pins. Tie the VCCD pins together as close as possible, and

decouple both supplies as near to the package as possible.

VSSA, VSSD (Ground Inputs)

The Winbond I5216 series utilizes separate analog and digital ground busses. The analog ground

(VSSA) pins should be tied together as close to the package as possible, and connected through a low-

impedance path to power supply ground. The digital ground (VSSD) pin should be connected through a

separate low impedance path to power supply ground. These ground paths should be large enough to

ensure that the impedance between the VSSA pins and the VSSD pin is less than 3Ω. The backside of

the die is connected to VSSD through the substrate resistance. In a chip-on-board design, the die attach

area must be connected to VSSD.

NC (No Connect)

These pins should not be connected to the board at any time. Connection of these pins to any signal,

ground or VCC, may result in incorrect device behavior or cause damage to the device.
