The AVR RISC Microcontroller Handbook is a comprehensive guide to designing with Atmel's AVR controller family, which is designed to offer high speed and low power consumption at a lower cost.

The main text is divided into three sections: Hardware, which covers all internal peripherals; Software, which covers programming and the instruction set; and Tools, which explains using Atmel's Assembler and Simulator (available on the Web) as well as IAR's C compiler.
