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

Selecting The Right Microcontrollers For Embedded Applications 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. http://www.elprocus.com/
Selecting The Right Microcontrollers For Embedded Applications Prepare a List of Required Hardware Interfaces ďƒ˜ These two types of interfaces will command the number of pins that will be essential by the microcontroller.

Selecting The Right Microcontrollers For Embedded Applications 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.

Selecting The Right Microcontrollers For Embedded Applications 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.

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.

Selecting The Right Microcontrollers For Embedded Applications Conclusion ďƒ˜ 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.
