GND
Ground pin.
All GND pins must be tied to ground.
Power pin.
PLCC : All VDD pins must be tied to 5 Volts.
TQFP : All VDD pins must be tied to 5v or 3.3v.
(Note that the VDETECT
pin must be set according to the selected voltage environment).
No Connects
These pins are not connected to any pads within the device, and can be
left open.

Note: All unused signal input pins should be tied to VDD or GND as applicable and must not be left floating. For high speed operation (XTAL >
10MHz), card designers are recommended to follow the guidelines for high-speed digital design such as maintaining PCB tracks as short
as possible, using a multi-layer PCB with separate power and ground planes, and using good-quality de-coupling capacitors.
Attention should be given to high frequency decoupling of power and ground pins due to the high frequency internal switching that occurs
under normal operation
