Propeller 2 Multicore Microcontroller
The “P2” Propeller P2X8C4M64P is a multicore microcontroller containing 8 identical 32-bit processors connected to a common hub.
The hub provides a shared RAM, a CORDIC math solver, and housekeeping facilities. Each of the 64 identical smart I/O pins are capable of many autonomous analog and digital functions.
The smart I/O pins are accessible by each processor to maximize application flexibility, and are externally powered at 3.3 V in blocks of four to maximize analog performance.
P2X8C4M64P Specifications Overview
Eight powerful 32-bit processors:
- Access to all I/O pins, plus four fast DAC output channels and four fast ADC input channels
