Correct answer is (c) ARDUINO Mini

The explanation: The Arduino Mini uses the Atmega168. Some other boards that USE this MICROCONTROLLER include the Arduino Diecimila which is a BIGGER development board than the Arduino Mini and can be used for projects that require a GREATER number of pins to operate.

Right answer is (a) Yes

To elaborate: The Atmega168, like most other chips has an index corner which is USED to IDENTIFY the numbering of the pins when reading the pin configuration of the chip. ALMOST all chips have a similar index corner without which, numbering of the pins would be very difficult.

Right option is (c) 1.8V to 5.5V

The BEST I can explain: The OPERATING voltage of the Atmega328 is 1.8V to 5.5V. Provide any voltage lower than that and the chip will not FUNCTION. But however, if any voltage higher than the rated voltage is PROVIDED there is a chance of DAMAGING the IC physically. So, under no circumstance should this chip be provided a voltage more than the rated voltage.

Correct CHOICE is (a) 8

To explain I would say: The Atmega2560 is CAPABLE of processing 8 BITS of data at a time and hence it has an 8-bit ARCHITECTURE. Other similar 8-bit processors INCLUDE the Intel 8080 Processor which ran on a similar 8-bit architecture.

Right option is (c) 32

The EXPLANATION is: There are 32 General-Purpose Registers in the chip, and they are all connected to the ALU (Arithmetic Logical UNIT) directly which allow 2 registers to be accessed in ONE instruction in a clock cycle.

Correct ANSWER is (a) 1

The explanation is: A COMPARATOR is basically used for comparing voltages. It takes 2 voltages as input and outputs the higher of the two. The ATMEGA2560 has 1 such comparator only.

The correct OPTION is (b) 32

Explanation: There are 32 General-Purpose Registers in the chip and they are all CONNECTED to the ALU (Arithmetic LOGICAL Unit) DIRECTLY which allow 2 registers to be accessed in ONE instruction in a clock cycle.

Correct answer is (d) 2.7V to 5.5V

Best explanation: The operating voltage of the ATMEGA32U4 is 2.7V to 5.5V. Provide any voltage lower than that and the CHIP will not function.

Right option is (d) 1.8V to 5.5V

To explain I would say: The operating VOLTAGE of the Atmega2560 is 1.8V to 5.5V. Provide any voltage lower than that and the chip will not function. But HOWEVER, if any voltage higher than the RATED voltage is provided there is a CHANCE of damaging the IC PHYSICALLY. So, under no circumstance should this chip be provided a voltage more than the rated voltage.

Right CHOICE is (b) 54, 16

The best explanation: The ATMEGA2560 has 54 Digital IO Pins and 16 Analog Pins, which, on the Arduino Mega are NUMBERED as D0 to D53 and A0 to A15 respectively. From them, pins D2 to D13 SUPPORT Pulse WIDTH Modulation.

Correct CHOICE is (a) 1

Explanation: A COMPARATOR is basically used for comparing VOLTAGES. It takes 2 voltages as INPUT and outputs the higher of the two. The Atmega32U4 has 1 such comparator only.

Right choice is (a) 6, 8

Easiest explanation: The Atmega168 has 8 ADC Pins and 6 PWM Pins. The ADC pins connect to the onboard Analog to Digital CONVERTOR of the Arduino and the PWM pins provide Pulse Width Modulated output SINCE a digital circuit like a MICROCONTROLLER cannot provide a PERFECT analog wave.

Correct answer is (C) 3

Explanation: The Atmega168 has a total of 3 timers, of which 2 are 8-bit timers and 1 is a 16-bit timer. The number of BITS here REPRESENTS the resolution of the timers, I.e. the number of bits each timer can STORE.

The correct option is (a) 8

Easy explanation: The ATMEGA32U4 is CAPABLE of PROCESSING 8 BITS of data at a time and HENCE it has an 8-bit architecture. Other similar 8-bit processors include the Intel 8080 Processor which ran on a similar 8-bit architecture.

The CORRECT ANSWER is (B) 8, 6

To explain I would say: 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.

The correct option is (d) 4

The best I can explain: The Atmega32U4 has a total of 4 timers, of which 1 is an 8-bit TIMER, 2 are 16-bit timers, and 1 is a 10-bit timer. The NUMBER of bits here REPRESENTS the resolution of the timers, I.e. the number of bits each timer can STORE.

For explanation: Both the Arduino Mega and the Arduino Mega ADK use the Atmega2560, however the only difference between the two boards is that the Arduino Mega ADK was specifically built with ANDROID PHONES in MIND and has a USB to HOST connector that can plug into your android smartphone.

Correct answer is (c) 1.8V to 5.5V

For explanation I WOULD say: The operating VOLTAGE of the Atmega168 is 1.8V to 5.5V. Provide any voltage lower than that and the chip will not function. But however, if any voltage higher than the RATED voltage is PROVIDED there is a chance of damaging the IC physically. So, under no CIRCUMSTANCE should this chip be provided a voltage more than the rated voltage.

Correct answer is (C) 32

The EXPLANATION: There are 32 General-Purpose Registers in the chip and they are all connected to the ALU (Arithmetic Logical Unit) directly which ALLOW 2 registers to be ACCESSED in one instruction in a clock cycle.

The correct choice is (a) YES, it does. It has a provision to programmatically CHANGE the brown-out threshold for the chip

The explanation is: The Atmega32U4 has a provision to change the brown-out threshold. A brown-out CONDITION occurs when there is a dip in supply voltage that’s being FED to the chip. If the chip continues to function at that time, then it would lead to wrong calculations being done, and that is HARMFUL especially in applications for different industries. Hence in that condition, the chip resets the operations and starts over.

Explanation: There are 32 General-Purpose REGISTERS in the chip and they are all connected to the ALU (Arithmetic Logical Unit) directly which ALLOW 2 registers to be accessed in ONE instruction in a CLOCK cycle.

Right CHOICE is (d) 6

Best explanation: The Atmega2560 has a total of 6 TIMERS, of which 2 are 8-bit timers and 4 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.
