On the other hand, you can purchase a 32-bit microcontrollers running at 48 MHz with similar memory for only 60 cents. It runs at 20 MHz and includes 32 KB of Flash and 2KB of RAM. It costs a little over $1 in volumes of around 10k pieces. So if you have built your early prototype using an Arduino then you may be able to use an 8-bit microcontroller in your final product.ДonвЂ™t let price alone though guide your decision and in many cases 32-bit microcontrollers can be cheaper than 8-bit chips.ДЇor example, the Atmega328p is the 8-bit microcontroller used the Arduino Uno. If an application does not have very high demands on processing power, and is of relatively small size, then it can make sense to consider an 8-bit microcontroller.ДЇor reference, most Arduinos are based on 8-bit microcontrollers. In general, 8-bit microcontrollers are geared toward lower end applications, and 32-bit ones are for the higher ends, with 16-bit for mid-end applications.Д«y far, most of the products I work on tend to incorporate 32-bit microcontrollers, but 8 or 16-bit microcontrollers can be a good choice for low-end, low-cost products. There are others, but these are the most popular ones. Microcontrollers for embedded systems mainly fall into three categories based on the width of their data buses: 8-bit, 16-bit and 32-bit. This is not just dependent on the raw clock speed it also depends on the data width of the processor and any hardware acceleration features included.

Beyond that, microcontrollers are distinguished by the amount of memory they have, the number and type of other peripherals integrated on the chip, and the speed at which they run user applications.

They have some digital IO ports, and at least one timer/counter.ДЄlso, other than very low-end microcontrollers, most have at least one UART for serial communications. They need a clock source, and this is normally provided by either an internal resistor-capacitor (RC) oscillator, or by using an external crystal for more timing critical applications. On top of a processing unit, they have a certain amount of flash that is used to store the application code, some SRAM, and, in most cases, some EEPROM. In this article, only microcontrollers that generally meet the above criteria will be presented.ДЄll modern microcontrollers share some basic features.

It also helps if the chosen microcontroller has a readily available development board.ДЇinally, development time can be significantly reduced if the selected microcontroller has extensive, fully debugged, software libraries with well documented Application Programming Interfaces, or APIвЂ™s. Support for the chosen platform is also very important вЂ“ not just from the vendor, but from the community at large.

The availability of the proper software and hardware tools is also a prime consideration. When selecting the right microcontroller for a project you must consider cost, performance, power consumption and overall size.
