Factors Affecting Choice of MCU
Memory requirement.I/O port requirement.Communication features required.Hardware peripherals required like timers, counters, ADCs,DACs, comparators, multipliers, PWM signal generator.Speed – affected by word length and clock frequency.Packaging, cost and availability.Power constraints.In-circuit programming and debugging facility.Availability of user documentation, development kits,software development tools and programmers.

Facilities Required in MCU Development Platform
Editor – required to write the program in assemblylanguage or in higher level language.Assembler – translates assembly language program tomachine code.Compiler – translates higher level language program tomachine code.Debugger – used to detect errors in program.

Facilities Required in MCU Development Platform
Programmer – hardware used to copy the machine codeinto the program memory of the MCU.Simulator – used to test the working of a program withoutloading it into the MCU.IDE – Integrated Development Environment – is the GUIfor all the development tools.Development board – hardware having the chosen MCUand associated peripheral devices.

Steps to Get Started with an MCU
Familiarize with the package and signals at various pins.Understand the internal architecture by going through theblock diagram.Study the assembly language instruction set.Practise assembly language programming.Understand how to use various internal facilities liketimers/counters, I/O, serial I/O, ADC/DAC, PWM etc.Understand how to program the microcontroller usinghigher level language like C/C++ etc.Understand how to connect external devices to themicrocontroller.
We may have to repeat all these steps several times to use anMCU comfortably.
