AVR Microcontrollers

AVR 8-bit RISC microcontrollers by Atmel are currently at the heart of the embedded technology platform we use in Physical Interaction Design research and courses at CCRMA. These chips have a modern Harvard Architecture, executing most instruction cycles in a single clock cycle. An extremely efficient open source C compiler is available, and these devices are used and supported by a large community of developers. The AVR architecture and instruction set is available in a large family of 8-bit devices that come in a variety of packages. AVR-series chips come with as little as 1 Kbyte of Flash program memory, up to 256 Kbytes; 32 bytes to 8 Kbytes of RAM; and up to 20 MHz clock speeds. Specialized AVR devices exist for automotive, LCD and lighting control, USB and radio applications. Code is easily portable between devices.
