Traditionally 32-bit microcontrollers have been seen as complex devices only suitable for processing-hungry applications in robotics and data acquisition. However with the advent of new architectures this perception is steadily being challenged. 32-bit devices are now widely available below $2, and simplified programming models enable those who once regarded 32-bit MCUs as out of range are now reconsidering their design roadmaps. Not only has ease-of-use improved substantially, but so has code size, with 32-bit code being the same size, or smaller, than 8-bit.

In this article we will explore the latest ease-of-use features and how tomorrow’s developers will be using 32-bit microcontrollers in a far wider array of applications, from home appliances to the most deeply embedded medical applications.
