Engineers designing high-performance, cost-, and power-sensitive applications such as vending machines, building management, and heating-ventilation-air conditioning (HVAC) systems, exercise equipment, and lighting control need highly integrated microcontrollers to reduce the system component count and fit their product requirements. There are also many wireless networking and infrastructure applications, Internet appliances, as well as special portable products that need off-the-shelf general-purpose microcontrollers. These applications require microcontrollers running at speeds greater than 33 MHz with on-chip RAM and flash memory, as well as an array of sophisticated peripherals that are easy to program in a high-level language.

In this article, Iıll discuss the key elements of a general-purpose microcontroller and their use in a real-time application. Iıll show you how the interaction of the peripherals with the processor is essential for collecting, processing, and outputting data. Iıll use the low-power Motorola MMC2107 32-bit microcontroller architecture as an example solution for designing a complex system using a minimum number of components.
