Introduction
  • Selecting the right microcontrollers for embedded
    applications can be a crucial task. Here we
    discusses the design challenges and system
    limitations of Microcontrollers in embedded
    applications.

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

How to Select the Right Microcontrollers for
Embedded Applications
  • Prepare a List of Required Hardware Interfaces
  • Select the Architecture
  • Recognize Memory Requirements
  • Observe Costs and Power Limitations
  • Pick a Development Kit

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.
  • Communication Interfaces
  • 2. Digital Inputs and Outputs

Prepare a List of Required Hardware Interfaces
  1. 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.
  • Dont 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 dont 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.

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 doesnt meet power necessities, then keep
    preparing the list down until you have a choice
    few.
  • Dont forget to observe the part price of the
    processor either.

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 isnt 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 hardwares, data transfer, PWM ports,
    packaging, power consumption, memory size, cost,
    etc.
