The Propeller 1 chip is a multicore microcontroller that is programmable in high-level languages (Spin™ and C) as well as a low-level (Propeller assembly) language. Application development is simplified by using the set of pre-built objects for video (NTSC/PAL/VGA), mice, keyboards, LCDs, stepper motors and sensors.

The Propeller is designed with an emphasis on general-purpose use, with powerful capabilities that are great for customized high-speed embedded processing, while maintaining low power, low current consumption and a small physical footprint. The Propeller's processors are all identical, each with its own separate memory, and each with an identical interface to all 32 I/O pins and internal shared memory. The architecture is built for swift processing of asynchronous events, equal access to internal and external resources, and dynamic speed and power when it's needed.

The P8X32A-D40 is most useful for prototyping in breadboarded or socketed circuits. The Propeller is easily connected to your computer's serial or USB port for programming. The Propeller chip can run on its own with a 3.3-volt power supply, internal clock, and with its internal RAM for code storage. Add an external EEPROM for non-volatile code storage and an external clock source for accurate timing.

Features

Multicore processing simplifies designs subject to asynchronous requirements
DIP package for easy prototyping with a breadboard
Built-in Spin language is easy to learn
PropGCC support provides a familiar feel for C/C++ programmers
Propeller Assembly language supports deterministic timing using single-path, multi-decision techniques
Internal or external clock sources provide flexible speed options
Power requirements: 2.7 to 3.3 VDC
Communication: Serial for programming
Dimensions: 0.48 x 2.0 x 0.13 in (12.3 x 51 x 3.41 mm)
Operating temp range: -67 to +257 °F (-55 to +125 °C)

Pin Assignments

P0-P31: General purpose I/O. Can source/sink 40 mA each at 3.3 VDC
P31: Rx from host (general purpose I/O after boot up)
P30: Tx to host (general purpose I/O after boot up/download)
P29: I2C SDA connection to external EEPROM (general purpose I/O after boot up)
P28: I2C SCL connection to external EEPROM (general purpose I/O after boot up)
Vdd: Power (3.3 VDC)
Vss: Ground (0 VDC)
BOEn: Brown Out Enable (active low). Must be connected to either Vdd or Vss. If low, RESn becomes a weak output (~5 KΩ) for monitoring purposes but can be driven low to cause reset. If high, RESn is a CMOS input with Schmitt Trigger.
RESn: Reset (active low). When low, resets the Propeller chip; all cogs disabled and I/O pins floating. Propeller restarts 50 ms after RESn transitions from low to high.
XI: Crystal / clock input. Can connect to crystal or oscillator
XO: Crystal Output. Provides feedback for an external crystal. Internal C and R selectable for crystals (no other components required)
