(5) A family of microcontrollers used in embedded systems from Atmel Corporation, San Jose, CA. Most AVR chips use 8-bit microprocessors except for the 32-bit AVR32. It is unclear what the name actually stands for; however, possibilities are "Advanced Virtual RISC" or "Alf and Vegard RISC," the latter being the first names of the Norwegian students who designed the architecture in 1996.
