The Propeller 40-Pin Micro is an evolutionary step up from the Parallax Basic Stamp.


Description [Hide]

This is Parallax’s all-custom microcontroller, with substantial capability not found in traditional microcontrollers.. The Propeller is a multi-processing chip, with shared memory and a built-in interpreter for programming in a high-level object-oriented language, called Spin™, and low-level (assembly) language. With the set of pre-built Parallax "objects" for video, mice, keyboards, NTSC/VGA displays, LCDs, stepper motors and sensors your application is a matter of high-level integration with Propeller. The Propeller chips are designed for high-speed embedded processing, while maintaining low power, low current consumption and a small physical footprint.

Pin Outs (see gallery for diagram):
Pin(s)
Description
P0-P31 General purpose I/O. Can source/sink 50 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 3.3 V power (2.7 - 3.6 VDC).
Gnd 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 K?) 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).

Cog Ram 512 x 32 bits each
I/O Pins 32 (simultaneously addressable by all eight cogs)
Current Source/Sink per I/O 50 mA
