Signal Descriptions
Signal Name
I/O
Description
General Purpose
P[Edge] [Row/Column Number*]_[A/B]
I/O
[Edge] indicates the edge of the device on which the pad is located. Valid
edge designations are L (Left), B (Bottom), R (Right), T (Top).
[Row/Column Number] indicates the PFU row or the column of the device on
which the PIC exists. When Edge is T (Top) or B (Bottom), only need to spec-
ify Row Number. When Edge is L (Left) or R (Right), only need to specify Col-
umn Number.
[A/B] indicates the PIO within the PIC to which the pad is connected. Some of
these user-programmable pins are shared with special function pins. These
pins, when not used as special purpose pins, can be programmed as I/Os for
user logic. During conguration the user-programmable I/Os are tri-stated
with an internal pull-up resistor enabled. If any pin is not used (or not bonded
to a package pin), it is also tri-stated with an internal pull-up resistor enabled
after conguration.
GSRN
I
Global RESET signal (active low). Any I/O pin can be GSRN.
NC
—
No connect.
GND
—
Ground. Dedicated pins.
VCC
—
Power supply pins for core logic. Dedicated pins.
VCCAUX
—
Auxiliary power supply pin. This dedicated pin powers all the differential and
referenced input buffers.
VCCIOx
—
Dedicated power supply pins for I/O bank x.
VCCPLL
—
PLL supply pins. Should be tied to VCC even when the corresponding PLL is
unused.
VREF1_x, VREF2_x
—
Reference supply pins for I/O bank x. Pre-determined pins in each bank are
assigned as VREF inputs. When not used, they may be used as I/O pins.
XRES
4
—
10K ohm +/-1% resistor must be connected between this pad and ground.
PLLCAP
4
—
External capacitor connection for PLL.
PLL, DLL and Clock Functions (Used as user programmable I/O pins when not in use for PLL or clock pins)

I
Optional feedback (DLL) input pads: ULM, LLM, URM, LRM, num = row from
center, T = true and C = complement, index A,B,C...at each side.
PCLK[T, C]_[n:0]_[3:0]
I
Primary Clock pads, T = true and C = complement, n per side, indexed by
bank and 0,1,2,3 within bank.
