Embedded - Microcontrollers
The Atmel AVR ATMEGA168-20MU microcontroller series is a highly versatile, 8-bit microcontroller architecture designed to meet a wide range of application requirements. It integrates many special purpose hardware peripherals and supports up to 64 KB of program memory. This makes it an excellent choice for embedded control applications such as motor control, robotics, sensor networks, and data acquisition. The ATMEGA168-20MU is a member of the AVR family of microcontrollers developed by Atmel. It is intended for use in low-power and cost-sensitive applications. The ATMEGA168-20MU is fabricate in Atmel\'s high-density non-volatile memory technology and is compatible with industry-standard instruction set. One of the unique features of the AVR family of microcontrollers is the presence of an Enhanced RISC (Reversible Instruction Set Computer) architecture. This architecture allows for a high degree of code efficiency and it has helped the AVR microcontrollers to be used in a wide range of application fields. Atmel provides extensive support for the development of applications on the ATMEGA168-20MU microcontroller. This support includes integrated development environments such as the AVR Studio, which provide a complete environment for programming and debugging AVR based applications. The AVR Studio also provides libraries of example applications and tutorials to help developers get started on their projects with the AVR microcontroller. The ATMEGA168-20MU microcontroller combines two sets of instructions and data processing units, the Enhanced RISC architecture and the AVR Instruction Set (AIS). The AIS architecture provides the ability to execute basic math, logic and control operations as well as vector instructions. The Enhanced RISC architecture includes the ability to perform a variety of arithmetic and logic functions including multiplication, subtraction, and bit shifting. These features allow the microcontroller to perform complex tasks with a minimum of code size and execution time. The ATMEGA168-20MU microcontroller incorporates the internal pull-up tri-state signal for I/O port pins. This feature allows the pins to be used for both input and output operations and provides a greater degree of flexibility. The microcontroller also contains an 8-bit timer/counter and 8-bit pulse-width modulation (PWM) units. Both of these units are attributed to a powerful 32-bit hardware multiplier/accumulator that allows the CPU to execute complex arithmetic and logic functions without the need for an external multiplier/accumulator. The ATMEGA168-20MU microcontroller also has on-chip debugging capabilities. This allows developers to easily monitor the execution of their programs when debugging or troubleshooting. This can reduce the amount of time needed to develop and debug many application. The ATMEGA168-20MU microcontroller is an excellent choice for a wide variety of embedded control applications. It provides developers with a powerful architecture as well as comprehensive development tools and example applications. The microcontroller is a cost-effective and efficient choice to meet the needs of many embedded control applications.
