Parallax P2 Edge Module - Datasheet

Pin Descriptions
Pin Name
Direction
Description
GND
-
Exposed Pad (underside of chip); ground for core and smart pins – internally
connected to exposed pad. Connect to ground plane for thermal dissipation.
TEST
I
Tied to ground
VDD
-
Core power
P0-63
I/O
Smart pins. P58-P63 serve in the boot process, then general purpose after.
Vxxyy
-
Power for smart pins in groups of 4: Pxx through Pyy
XO
O
Crystal Output. Provides feedback for an external crystal, or may be left
disconnected depending on CLK Register settings. No external resistors or
capacitors are required.
XI
I
Crystal Input. Can be connected to the output of crystal/oscillator pack (with
XO left disconnected), or to one leg of crystal (with XO connected to the other
leg of crystal or resonator) depending on CLK Register settings. No external
resistors or capacitors are required.
RESN
I
Reset (active low). When low, resets the Propeller: all cogs disabled and I/O
pins floating. Propeller restarts 3 ms after RESn transitions from low to high.
Connect to a resistor to pull up to 3.3 V.
