How to Select the Right Microcontrollers for Embedded Applications
There are several reasons to select the microcontrollers for embedded applications, namely…
Low cost.
Higher integration level.
Increased reliability.
Space savings

Selecting The Right Microcontrollers For Embedded Applications
Prepare a List of Required Hardware Interfaces
Using the basic hardware block diagram of the microcontroller
Prepare a list of all the peripheral interfaces that the microcontroller will need to support.
There are two common types of interfaces in the microcontroller that need to be listed.
1. Communication Interfaces
2. Digital Inputs and Outputs

Prepare a List of Required Hardware Interfaces1.Communication
Interfaces These are peripherals like USB, SPI, I2C, UART, and so on.
These are greatly disturbing how much program space in the microcontroller will need to support.
2. Digital Inputs and Outputs
(A to D) analog to digital inputs.
Pulse width modulations.

Prepare a List of Required Hardware Interfaces
These two types of interfaces will command the number of pins that will be essential by the microcontroller.

Select The Architecture
The selection of architecture can greatly affect the microcontroller for embedded applications.
Start getting an idea of the microcontroller architecture that will be required.
Keep in mind possible future requirements.
Don’t forget that microcontroller selection can be an iterative procedure.

Recognize Memory Requirements
The two very critical memory components of microcontrollers are RAM and Flash.
Ensure that you don’t run out of spaces for variable and program.
It is far simpler to choose a portion with too much of these features than not sufficient.
You can constantly start with more and then later move to a more controlled part in the same chip family.

Recognize Memory Requirements
A designer can guess how much memory will be needed for the application.
Using the software architecture and the communication peripherals.

Selecting The Right Microcontrollers For Embedded Applications
Observe Costs and Power Limitations
Observe the power necessities and the cost of the microcontroller.
If the microcontroller will be powered by a battery & mobile.
Then making sure the portions are low-power is absolutely dangerous.
If it doesn’t meet power necessities, then keep preparing the list down until you have a choice few.
Don’t forget to observe the part price of the processor either.

Selecting The Right Microcontrollers For Embedded Applications
Pick a Development Kit One of the best portions of choosing a microcontroller
Discover a development kit to play with and observe the internal working of the microcontroller.
If a kit isn’t existing then the particular part is most likely not a good choice.
They should go back a few steps and discover a better part.
Most of the kits today cost under $100.

Pick a Development Kit Paying any more than that is just too much.
Another portion may be a better choice.

Conclusion We can conclude that there are many features to consider while
choosing a microcontroller for embedded applications. Before starting an embedded project which needs a microcontroller, one should effort on technical aspects will assist you to select a microcontroller for specific embedded applications. They are a list of hardware’s, data transfer, PWM ports, packaging, power consumption, memory size, cost, etc.
