P2 Edge Module with 32MB RAM

P2 Edge Module with 32MB RAM Overview

The P2 Edge Module with 32MB RAM is a simple way to get started with the Propeller 2 multicore microcontroller. In addition to speeding development, this module provides an optimal P2 building block for system integrators and designers to include in their products.

The Propeller 2 P2X8C4M64P is an 8-core 32 bit CPU with 32-bit timers, 64-bit CORDIC math solver, and custom analog pad rings with Smart-pin functionality at all 64 I/O pins. Each Smart I/O pin is capable of many autonomous analog and digital functions, including ADC, DAC, PWM, USB, SERIAL, Waveform generation, SMPS, Comparator, SCHMITT and LOGIC modes.

The P2 Edge Module with 32MB RAM includes the 100-pin TQFP P2X8C4M64P, core and I/O power regulators, power filtering capacitors, crystal, flash memory, boot configuration switches, microSD card socket, and two user-configurable on-board LEDs to indicate system states. This version of the Edge module adds 32MB of RAM to the original P2-EC, and has 46 free I/O’s available at the edge connector. The PCB's multi-layer design features solid thermal and signal reference planes isolating each signal layer. The design is optimized for low-noise analog and digital operation, and with low temperature rise even at high-speed operation.

For development, the P2 Edge Module fits in the card edge socket of the spacious P2 Edge Module Breadboard, the compact P2 Edge Mini Breakout Board, or the bare-bones P2 Edge 80-pin Adapter Kit.  For product integration,  several edge socket choices are available from our P2 Components shop page. This arrangement allows developers to integrate the Propeller 2 into products without the need for multi-layer cost or expertise.
