  18. 18. Freescale HC12 Aaron Harris The HC12 family of microcontrollers are 16 bit processors with a decent amount of features for a relatively low cost. These processors started as an enhanced 16 bit version of the popular 8 bit HC11. They contain many of the modules you would expect from a microcontroller, such as SCI, SPI and CAN interfaces, an A2D module and a timer module. The HC12 is perfect for a system that is not overly complex yet still requires many different types of communication or control.

With clock rates that can reach 300 MHz, the ColdFire can be quite powerful for an embedded system. This microcontroller is good for a system that is complex and requires many of the different resources available in the ColdFire family.

  46. 46. dsPIC30F3010 Tim Raabe The dsPIC is a great choice for motor controlling. It has dedicated motor control hardware, and is easy to set up to control many types of motors. A big benefit of Microchip devices is the free IDE and C compiler for students. Additionally, the development kit can control 48v motors at 2.2A. Along with motor control features, the dsPIC also has built in DSP functionality. This can allow more complex algorithms on a small, cheap 16bit micro.

  48. 48. LM3S811 Microcontroller Tim Raabe The Luminary Micro seems like a good choice if a low cost 32 bit processor is needed. It actually has dedicated hardware for both multiplication and division, which should add speed over a 16 bit, or 32 bit processor which relies on software algorithms for both multiplication and division. The evaluation board for this device is also very affordable, cheap enough that several could be used for controlling a single robot if needed.
