A real processor: Atmel ATmega64

ATmega64 belongs to the AVR family of microprocessors.

AVR architectecture conceived by two students at the Norwegian Institute of Technology: Alf Egil Bogen and Vegard Wollan

A range of (almost) compatible 8-bit CPU chips designed for embedded use (microcontrollers).

Typical uses: appliances such as VCRs, washing machines or telephones and control system, e.g. cars

Market for embedded CPUs larger in number (but not $) than market for general purpose machines (PC etc.)

250 million AVRs sold in 2004.

Competes with PIC (Microchip), ARM and others in embedded market.

ATtiny11: 8 pin package, 1Kb flash program memory, 32 bytes SRAM, max clock speed 6 Mhz, power consumption 1.5-6mW (2 AA batteries will run one for a months), less than $1 in large quantities

ATmega64: 64 pin package, 4Kb flash program memory, 32 bytes SRAM, maxclock speed 16 Mhz, 4 Timer/counters 8 channel 10-bit ADC, 2 Serial UARTs, 2 8-bit PWM Channels
