How much power does ATmega328P use?
The ATmega328P, used on popular boards like the SparkFun RedBoard, Arduino Uno, and Pro Mini are actually quite power hungry. The RedBoard and Arduino Uno, draw around 15mA minimum, which doesn’t sound like much but as you’ll see in this guide, we can drastically bring that down with just a few tricks.
How many ADC unit does the Atmega328 have?
8 ADC Pins
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.
What is the difference between ATmega328P and Atmega328?
There is no major functional difference between them except for power. This microcontrollers are mostly used in Arduino’s. The Atmega 328 function the same like Atmega 328p but the 328p has very low power consumption using the ATMEL’s PicoPower Features. Hence P stands for PicoPower.
What is the meaning of 328 in Atmega328?
328 in Atmega 328 means.. 32kB of ISP flash and 8 bit controller in the microcontroller chip , i.e the input output processing is done on 8 bits.
Is ATmega328P AEC Q100 qualified?
Atmel microcontrollers are fully engineered to fulfill the quality requirements of OEMs in their drive towards zero defects. Several AVR microcontrollers are qualified for operation up to +150°C ambient temperature (AEC-Q100 Grade0).
How much current does an ATmega328 draw?
At 20MHz/5V, an active 328 draws about 20mA = 100mW, but at low clock speed and voltage, 1mW is very doable.
What is the lowest power consumption mode in an atmega?
Atmel’s picoPower technology employs a number of techniques that result in the lowest sleep mode power consumption of any microcontroller on the market today. The processes used in AVR MCUs support a power supply voltage range from 1.8V to 5.5V. The 1.8V operation is a true 1.8V operation.
How many timers does ATmega328P?
three timer
The Atmega328P has a total of three timer/counters named Timer/counter 0, Timer/counter 1, and Timer/counter 2. The first and last of these are both 8-bit timer/counters and have a maximum value of 255, while Timer/Counter 1 is 16 bits and its maximum is 65,535.
