Parallax Propeller 2 (P2) Multicore Microcontroller (MCU)

Added to your shopping cart

Parallax Propeller 2 (P2) Multicore Microcontroller (MCU) comes with 8 identical 32-bit processors connected to a common hub. This hub provides a shared RAM, a CORDIC math solver, and housekeeping facilities. The Propeller 2 MCU offers 64 identical smart I/O pins that are capable of many autonomous analog and digital functions. The smart I/O pins are accessible by each processor to maximize application flexibility. These I/O pins are externally powered at 3.3V in blocks of four to maximize the analog performance. The Propeller 2 MCU provides six different clock modes that are under software control with glitch-free switching between the sources. This MCU incorporates a central hub with 512KB of contiguous RAM in a 20-bit address space. The Propeller 2 MCU features 512-longs of dual-port register RAM for code and fast variables. This MCU is available in a 14mm x 14mm exposed-pad 100-pin Thin Quad Flat Pack (TQFP) package.
