The Propeller chip (see "Eight 32-Bit Cores
Take Flight In Multiprocessor Microcontroller"
at www.electronicdesign.com, ED Online
12235) has found a home in the $59 24-pin SpinStamp Microcontroller module from Parallax. It is the same form factor as the Basic Stamp. The Propeller packs eight 32-bit processors. Each has32 kbytes of RAM and 32 kbytes of ROM. They' reprogrammed using the
Spin programming language. This 3.3-V part contains its own voltage-regulator accepting a 5.5- to 12-V power source. It can be bypassed
with a 5-V regulated source. Only half of the
Propeller's 32 I/O pins are available on the
module.
