Which Arduino Boards use the Atmega328?Ĭalrification: The Arduino Uno uses the Atmega328. There are _ ADC and _ PWM Pins on the Atmega328.Ĭalrification: The Atmega328 has 8 ADC Pins and 6 PWM Pins, which are to be connected to the ADC that’s built in to the Arduino Uno and the PWM pins provide Pulse Width Modulated output since a digital circuit like a microcontroller cannot provide a perfect analog wave.ĥ. The Atmega328 has 1 such comparator only.Ĥ. It takes 2 voltages as input and outputs the higher of the two. How many comparators does the Atmega328 have?Ĭalrification: A comparator is basically used for comparing voltages. the number of bits each timer can store.ģ. The number of bits here represents the resolution of the timers, I.e. How many timers does the Atmega328 have?Ĭalrification: The Atmega328 has a total of 3 timers, of which 2 are 8-bit timers and 1 are 16-bit timers. The Atmega328 has 32K bytes of flash memory.Ģ. How much flash memory does the Atmega328 have?Ĭalrification: A flash memory is a type of non-volatile memory, which does not get erased when the power supply is cutoff from the chip. Typical data types are bit, sbit, sfr, float, signed char,unsigned char, enum, signed int etc.Ībove mentioned microcontroller interview questions and answers set is very useful forĮngineers appearing for interview in different job positions such as microcontroller programmer at senior as well asįresher level as well as microcontroller based board interfacing related jobs.Īlso refer C programming FAQs which are a must for microcontroller programming job position.Arduino Multiple Choice Questions on “Microcontroller Specifications – AtMega 328”.ġ.
