How much flash memory does the Atmega328 have?
A. 13K bytes
B. 32K bytes
C. 256K bytes
D. 16K bytes
Explanation: A flash memory is a type of non-volatile memory, which does not get erased when the power supply is cutoff from the chip. The Atmega328 has 32K bytes of flash memory.
How many timers does the Atmega328 have?
Explanation: The Atmega328 has a total of 3 timers, of which 2 are 8-bit timers and 1 are 16-bit timers. The number of bits here represents the resolution of the timers, I.e. the number of bits each timer can store.
How many comparators does the Atmega328 have?
Explanation: A comparator is basically used for comparing voltages. It takes 2 voltages as input and outputs the higher of the two. The Atmega328 has 1 such comparator only.
There are __ ADC and __ PWM Pins on the Atmega328.
A. 9, 7
B. 8, 6
C. 10, 1
D. 5, 18
Explanation: 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.
