VDD
-
Power Positive supply for I/O and some logic.
82
GND
-
Power Ground reference for logic and I/O pins.
83
VCCPHY
-
Power VCC of the Ethernet PHY.
84
VCCPHY
-
Power VCC of the Ethernet PHY.
85
GNDPHY
-
Power GND of the Ethernet PHY.
86
GNDPHY
-
Power GND of the Ethernet PHY.
87
GND
-
Power Ground reference for logic and I/O pins.
88

89
TRST
I
TTL
JTAG TRST.
PB6
I/O
TTL
GPIO port B bit 6.
90
C0+
I
Analog Analog comparator 0 positive input.
PB5
I/O
TTL
GPIO port B bit 5.
91
C0o
O
TTL
Analog comparator 0 output.
PB4
I/O
TTL
GPIO port B bit 4.
92
C0-
I
Analog Analog comparator 0 negative input.
93
VDD
-
Power Positive supply for I/O and some logic.
94
GND
-
Power Ground reference for logic and I/O pins.
95
NC
-
-
No connect. Leave the pin electrically unconnected/isolated.
96
NC
-
-
No connect. Leave the pin electrically unconnected/isolated.
GNDA
97
-
Power The ground reference for the analog circuits ( Analog Comparators,
etc.). These are separated from GND to minimize the electrical
noise contained on VDD from affecting the analog functions.
VDDA
98
-
Power The positive supply for the analog circuits (ADC, Analog
Comparators, etc.). These are separated from VDD to minimize
the electrical noise contained on VDD from affecting the analog
functions. VDDA pins must be supplied with a voltage that meets
the specification in “Recommended DC Operating
Conditions” on page 513, regardless of system implementation.
99
NC
-
-
No connect. Leave the pin electrically unconnected/isolated.
100
NC
-
-
No connect. Leave the pin electrically unconnected/isolated.
a. The TTL designation indicates the pin has TTL-compatible voltage levels.
