Function
VDD
I Power supply for Power supply pins for the internal
internal power core power. All the VDD pins must
be connected to the system power
supply. This LSI does not operate if
there is a pin left open.
VSS
I Ground for
Ground pins for the internal core
internal power and power and I/O circuits. All the VSS
I/O circuits
pins must be connected to the
system power supply (0 V). This LSI
does not operate if there is a pin left
open
VDDQ
I Power supply for Power supply pins for the I/O pins.
I/O circuits
All the VDDQ pins must be
connected to the system power
supply. This LSI does not operate if
there is a pin left open.
VDD_PLL1 I
Power supply for Power supply pins for the on-chip
PLL1
PLL1 oscillator. This LSI does not
operate if there is a pin left open.
VSS_PLL1 I
Ground for PLL1 Ground pins for the on-chip PLL1
oscillator. This LSI does not operate
if there is a pin left open.
VDD_PLL2 I
Power supply for Power supply pins for the on-chip
PLL2
PLL2 oscillator. This LSI does not
operate if there is a pin left open.
VSS_PLL2 I
Ground for PLL2 Ground pins for the on-chip PLL2
oscillator. This LSI does not operate
if there is a pin left open.
EXTAL
I Crystal
Connected to a crystal resonator. An
resonator/external external clock signal can also be
clock
input to the EXTAL pin.
XTAL
O Crystal resonator Connected to a crystal resonator.
CLKOUT
O System clock
output
Supplies the system clock to external
devices.
