Key Factors to Consider When Selecting a Microcontroller

When selecting a microcontroller we have basic factors you need to put into consideration, as stated below:

The Number of Input/output Pins

Find out the number of input/output pins that are going to be required for the application.

The Interfaces Needed

What interfaces are going to be required? For instance, if PWM is needed, you will have to consider microcontrollers that have PWM outputs like the PIC17C42.

Memory Requirements

Take note of the size of the memory that is required for the task.

Processing Speed Required

How fast the instructions need to be processed is also a key factor to consider.

The Number of Interrupts Required

How many events will require interrupts in your task?
