Product Description

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.

Features:

  • Propeller 2 Engineering Sample Rev C silicon, approved for future production chips
  • Eight 32-bit processors on a shared RAM with access to 64 identical smart I/O pins
  • 14 x 14 mm exposed-pad 100 pin TQFP package
  • Shipped in ESD foam lined box for small quantities, and in trays of 90 for large quantities
  • Silicon designed and wafers made in the USA; chips packaged in the Philippines

You may program the P2-ES Rev C silicon with the Propeller Tool 2.0 (Alpha) and other free IDE and language tools available for download from propeller.parallax.com.

See the Propeller 2 Documentation (Rev B/C Silicon) for the most complete information.

Specifications:

Eight 32-bit identical processors:

  • Access to all I/O pins, plus four fast DAC output channels and four fast ADC input channels
  • 512 longs of dual-port register RAM for code and fast variables
  • 512 longs of dual-port lookup RAM for code, streamer lookup, and variables
  • Ability to execute code directly from register RAM, lookup RAM, and hub RAM
  • ~350 unique instructions for math, logic, timing, and control operations
  • 2-clock execution for all math and logic instructions, including 16 x 16 multiply
  • 6-clock custom-bytecode executor for interpreted languages
  • Ability to stream hub RAM and/or lookup RAM to DACs and pins or HDMI modulator
  • Ability to stream pins and/or ADCs to hub RAM
  • Live colorspace conversion using a 3 x 3 matrix with 8-bit signed/unsigned coefficients
  • Pixel blending instructions for 8:8:8:8 data
  • 16 unique event trackers that can be polled and waited upon
  • 3 prioritized interrupts that trigger on selectable events
  • Hidden debug interrupt for single-stepping, breakpoint, and polling

Central hub serving the processors:

  • 512 KB of contiguous RAM in a 20-bit address space
  • 32-bits-per-clock sequential read/write for all cogs, simultaneously
  • readable and writable as bytes, words, or longs in little-endian format
  • last 16KB of RAM is write-protectable

32-bit, pipelined CORDIC solver with scale-factor correction

  • 32-bit x 32-bit unsigned multiply with 64-bit result
  • 64-bit / 32-bit unsigned divide with 32-bit quotient and 32-bit remainder
  • 64-bit → 32-bit square root
  • Rotate (X32,Y32) by Theta32 → (X32,Y32)
  • (Rho32,Theta32) → (X32,Y32) polar-to-cartesian
  • (X32,Y32) → (Rho32,Theta32) cartesian-to-polar
  • 32 → 5.27 unsigned-to-logarithm
  • 5.27 → 32 logarithm-to-unsigned
  • Cogs can start CORDIC operations every 8 clocks and get results 55 clocks later
  • 16 semaphore bits with atomic read-modify-write operations
  • 64-bit free-running counter which increments every clock, cleared on reset
  • High-quality pseudo-random number generator (Xoroshiro128**), true-random seeded at start-up, updates every clock, provides unique data to each cog and pin
  • Mechanisms for starting, polling, and stopping cogs
  • 16 KB boot ROM
  • Loads into last 16 KB of hub RAM on boot-up
  • SPI loader for automatic startup from 8-pin flash or SD card
  • Serial loader for startup from host
  • Hex and Base64 download protocols
  • Terminal monitor invocable via “> ” (greater than followed by a space) and then CTRL+D
  • TAQOZ Forth invocable via “> ” (greater than followed by a space) and then ESC

64 Smart I/O pins:

  • 64 identical Smart I/O pins, externally powered in blocks of 4
  • 8-bit, 120-ohm (3 ns) and 1 k-ohm DACs with 16-bit oversampling, noise, and high/low digital modes
  • Delta-sigma ADC with 5 ranges, 2 sources, and VIO/GIO calibration
  • Several ADC sampling modes: automatic 2n SINC2, adjustable SINC2/SINC3, oscilloscope
  • Logic, Schmitt, pin-to-pin-comparator, and 8-bit-level-comparator input modes
  • 2/3/5/8-bit-unanimous input filtering with selectable sample rate
  • Incorporation of inputs from relative pins, -3 to +3
  • Negative or positive local feedback, with or without clocking
  • Separate drive modes for high and low output: logic / 1.5 k / 15 k / 150 k / 1 mA / 100 µA / 10 µA / flat
  • Programmable 32-bit clock output, transition output, NCO/duty output
  • Triangle/sawtooth/SMPS PWM output, 16-bit frame with 16-bit prescaler
  • Quadrature decoding with 32-bit counter, both position and velocity modes
  • 16 different 32-bit measurements involving one or two signals
  • USB full-speed and low-speed (via odd/even pin pairs)
  • Synchronous serial transmit and receive, 1 to 32 bits, up to clock/2 baud rate
  • Asynchronous serial transmit and receive, 1 to 32 bits, up to clock/3 baud rate

Clock Modes:

  • Six different clock modes, all under software control with glitch-free switching between sources
  • Internal 20 MHz+ RC oscillator, nominally 25 MHz, used as initial clock source
  • Crystal oscillator with internal loading caps for 7.5 pF/15 pF crystals, can feed PLL
  • Clock input, can feed PLL
  • Fractional PLL with 1..64 crystal divider → 1..1024 VCO multiplier → optional (1..15)*2 VCO post-divider
  • Internal ~20 kHz RC oscillator for low-power operation (130 µA)
  • Clock can be stopped for lowest power until reset (100 µA, due to leakage)
