Atmel's low power, high performance AVR microcontrollers handle demanding 8- and 16-bit applications. With a single cycle instruction RISC CPU, innovative picoPower® technology, and a rich feature set, the AVR architecture ensures fast code execution combined with the lowest possible power consumption.

Whether you program in C or assembly, the tuned AVR instructions decrease program size and development time. The well-defined I/O structure limits the need for external components and reduce development cost. A variety of internal oscillators, timers, UARTs, SPIs, Pulse Width Modulation, pull-up resistors, ADCs, Analog Comparators and Watch-Dog Timers are some of the features available for creative engineers.

Download the free AVR Studio® and start writing and debugging code instantly! Learn only one tool chain with AVR Studio supporting all AVR devices and development tools, including Starter Kits, Evaluation Kits and Reference Designs. A comprehensive collection of application notes also kick-start troublesome tasks.

Since the introduction of the classic AT90S1200 device with on-chip in-system programmable Flash and EEPROM in 1997, today's large AVR microcontroller portfolio consists of devices sharing a single CPU architecture. This makes it easy to find THE AVR microcontroller for your application.
