HARDWARE

The Propeller 2 microcontroller's pin layout and simpliﬁed connections are described here for conceptual

reference. For most prototyping uses, Parallax recommends a pre-made Propeller 2 circuit, like the P2 Edge

Module (#P2-EC) or Propeller 2 Evaluation Board (#64000) that includes all the recommended connections and

layout design rules. Visit the Propeller 2 section of the Parallax online store for chips, evaluation boards,

accessories, and developer starter kit bundles.

Pin Descriptions

The Propeller 2 (P2X8C4M64P) features notable power and thermal considerations in its pinout:

● A large exposed under-side pad serves both as a ground reference (GND) for the core and I/O pins as well

as a heatsink to cool the silicon

● Multiple power pins (VDD) spaced regularly around the chip allow clean core power references across the

entire chip

● Multiple I/O power pins (Vxxyy) spaced regularly around the chip provide ﬂexibility for the isolated,

ultra-stable power references required for clean DAC and ADC I/O operations
