Device supply. Requires a 10 nF and 0.1 µF
I/O power supply. Sets the logic ‘1’ voltage level
Interrupt Request, active low. A 10 KΩ pull-up
resistor is required if this ball drives an input. A 10
KΩ pull-up resistor is recommended even if this
ball is not used.
Deep Power-Down. Used to enter and exit Deep
Power-Down mode. Pin is assigned A0 instead of
DPD when working in 8-bit mode.
capacitor.
range of I/O balls. VCCQ may be either 2.5V to
3.6V or 1.65V to 2.0V. Requires a 10 nF and
0.1 µF capacitor.
Ground. All VSS balls must be connected.
Reserved. All reserved signals are not connected
internally and must be left floating to guarantee
forward compatibility with future products.
Mechanical. These balls are for mechanical
placement, and are not connected internally.
Alignment. This ball is for device alignment and is
not connected internally.
