The ATMEGA168-20PU is an 8-bit, low-power AVR RISC-based Microcontroller Unit that combines 512B EEPROM, an 8-channel/10-bit A/D converter (TQFP and QFN/MLF), 16kB ISP flash memory, and an 8-channel/10-bit A/D converter. It also has debugWIRE for on-chip debugging. The input voltage range for the device is 2.7 to 5.5 volts, and it has a maximum throughput of 20 MIPS @ 20 MHz.
The amount of current consumed is determined by different parameters, including the switching rate of the I/O pins, operating voltage, operating frequency, loading of the I/O pins, the code performed, and the temperature of the surrounding environment. The operating voltage and frequency are the most important considerations.
The differential current drawn by the watchdog timer can be calculated by taking the difference between the amount of current consumed in power-down mode when the watchdog timer is active and the amount of current consumed in power-down mode when the watchdog timer is disabled.

Frequently Asked Questions
What Is AVR Microcontrollers?
Atmel has been the sole developer of the AVR family of microcontrollers since 1996; in 2016, Microchip Technology purchased the company. These are single-chip microcontrollers with a modified Harvard architecture that uses the RISC instruction set. The AVR family of microcontrollers was an early adopter of on-chip flash memory for storing code. There were other families of microcontrollers available at the time that used EPROM or EEPROM, which allowed for one-time programming. The AVR microcontroller family was an early adopter of flash memory on the silicon die.
AVR microcontrollers are utilized in a wide variety of embedded system applications. Because they are included in many of the open hardware development boards produced by Arduino, they are particularly common in embedded systems used in educational environments and those catering to hobbyists.
Why is it called AVR?
The positive electrode is positioned in the right shoulder and is referred to as AVR (augmented Vector Right). Because the positive electrode is placed on the left side of the body, the abbreviation “AVL” refers to the fact that the left shoulder is the target. The term “augmented Vector Foot” (aVF) refers to the location of the positive electrode on foot.
Is Arduino an AVR microcontroller?
The Arduino is a microcontroller based on the AVR architecture loaded with specialized software that enables users to interact with the Arduino environment. AVRs can be utilized independently with the addition of a few more components to provide support as needed. The AVR (chip) and breadboard have a combined role in the Arduino system. Since AVR only consists of a single chip, it is necessary to use a breadboard.
What Is The Most Powerful AVR Microcontroller?
The ATmega328P is an 8-bit AVR microcontroller with high performance but low power consumption. Its innovative RISC architecture allows it to achieve the greatest single-clock cycle execution of 131 adequate instructions, making it one of the most power-efficient microcontrollers. It is a typical component of Arduino boards, such as the Arduino Fio and the Arduino Uno, where it is used as a processor.
What is AVR microcontroller programming?
A reduced instruction set computing (RISC) microprocessor with 8 bits is the foundation for the AVR microcontroller. An AVR programmer allows the user to teach a microcontroller to carry out a particular activity by writing those instructions into the device’s memory in the form of operating instructions. Microcontrollers from the AVR family are frequently utilized in the process of developing new pieces of hardware and in robotics.
