Popular Microcontrollers

Embedded methods aren’t simply complicated tasks in digital laboratories–they are current in on a regular basis units. Each cellular system, electrical toy or kitchen equipment has some digital board which often features a programmable device–microcontroller. It is a particular microprocessor with peripheral units and I/O ports. Relying on the amount of the system the producer can resolve whether or not to develop an ASIC–a devoted built-in circuit which performs all capabilities for this system or to make a normal board with discrete elements. In each instances some microcontroller is used, both as a gentle core in ASIC or a normal built-in circuit.

There’s a plethora of selections from open-source tasks to numerous IP cores with important royalties for every system. Regardless of this selection there are few microcontroller households which are in style due to their flexibility, highly effective growth instruments or due to historic causes.


That is presently the most well liked RISC core utilized in virtually all cell phones, moveable units and lots of different purposes. It has highly effective instruction set, low consumption, provides straightforward integration and there are various good growth instruments for simple growth and debugging. The ARM core can also be utilized in many in style microcontroller households from Atmel, Luminary Micro (now Texas Devices), NXP and lots of different producers. These microcontrollers are highly regarded amongst embedded engineers and are utilized in numerous purposes from automotive trade to interest tasks.


This is among the hottest microcontroller households from Atmel. It’s also highly regarded amongst interest engineers and it’s utilized in many tasks from easy LED controllers to complicated communication units. The RISC structure provides quick execution and low energy consumption. Improvement instruments can be found without cost which is a superb bonus for electronics fans. AVR is a direct competitor to Microchip’s PIC. Some favor AVR, others like AVR. There isn’t a clear winner. Each households work effectively. It’s as much as the developer/programmer what he like or prefers.


It is a main microcontroller household from Microchip. PICs can be found in very small packages with solely few pins and likewise as highly effective 32-bit microcontrollers with many peripheral modules and I/O pins. They’re highly regarded amongst interest engineers–in interest tasks you’ll discover both AVR or PIC.


It is a very outdated 8-bit microcontroller structure that has managed to outlive for greater than 30 years. Many glorious compilers, plenty of code examples and easy growth has contributed to the recognition of this household. This core remains to be utilized in many fashionable microcontrollers from Silabs, NXP, Atmel and lots of different microcontroller producers. It is extremely possible that the 8051 is probably the most broadly used core in embedded purposes. In fact, many new designs will most likely use ARM or another superior structure, however due to recognition of the 8051 household up to now and availability of growth instruments it’s nonetheless utilized in many purposes.
