  2. Vacuum tube computers www.williamson-labs.com/480_cpu.htm SAGE Blockhouse/Computer:10,170m2, 250 tons, houses More than 200,000 vacuum tubes @ 3,000,000 Watts

  3. Transistor Computers • 2nd Generation • From 1956 • Half a room The Harwell Dekatron Computer under restoration at the British National Museum of Computing

  4. Invention of ICs • 3rd generation IBM 360 made by ICs (1964)

  5. First microprocessors/Microcontrollers • TI TMS1000 • 4004 (from Intel) • 6800 (Motorola) TI TMS1000 (1971-1974) http://www.antiquetech.com/ Intel 4004 (1971) www.computerhistory.org PICO1 (1971) http://en.wikipedia.org/wiki/Microprocessor Motorola MC6800 (1974) http://en.wikipedia.org/wiki/Motorola_6800

  6. Now! Vacuum tubes (1st generation) Transistors (2nd generation) 1956 ICs (3rd Gen.) 1971 Microprocessors/MCUs time

  7. General Purpose Microprocessors vs. Microcontrollers • General Purpose Microprocessors • Microcontrollers

  8. Most common microcontrollers • 8-bit microcontrollers • AVR • PIC • HCS12 • 8051 • 32-bit microcontrollers • ARM • AVR32 • PIC32 • CodeFire • PowerPC

  9. AVR internal architecture 9

  10. AVR different groups Classic AVR e.g. AT90S2313, AT90S4433 Mega e.g. ATmega8, ATmega32, ATmega128 Tiny e.g. ATtiny13, ATtiny25 Special Purpose AVR (Application Oriented AVR) e.g. AT90PWM216,AT90USB1287 XMega New features like DMA, DAC, crypto engine, etc. CBGA TSSOP SOIC 10

  11. Let’s get familiar with the AVR part numbers ATmega128 Atmel group Flash =128K ATtiny44 AT90S4433 Atmel Flash =4K Atmel Classic group Tiny group Flash =4K 11
