Electronic Handyman (2) architecture of AVR microcontroller

The steady progress in the field of microcontrollers and microprocessors has produced new, powerful devices which come in standard IC cases yet easily match the computing power of first-generation PCs. The best known representatives of this new group are the well-established PIC devices from Microchip. However, these are now facing serious competition from Atmel’s AVR chips. In this article we have a look at the AT90S1200, the first member of this new controller family.
