1、December 2004,Introduction,Atmel MCU Training - ASIA 2004,2,The beginning,AVR started as a student project / diploma thesis at NTNU (University of Trondheim) In 91/92 the students Alf-Egil Bogen and Vegard Wollan started their idea of designing“a perfect RISC processor” The results where a processor

2、; with assembler and simulator. They named it RISC and it was used in several ASICs by a local ASIC company. But in 1995 the time was right tomarket it as a dedicated product.,3,Atmel Corporation,Atmel Corporation was choicen as partner; due to that they where, and still are, the worlds leading vend

3、or of FLASH and EEPROM memories. What could Atmel offer RISC? Technology RISC could become one of the first microcontrollers with Flash program memory The competitors program memory where mainly EPROM or ROM Semiconductor fabs Atmel had their own fabs Better control on production and technology Esta

4、blished sales force Atmel was established in 1984 and had in 1995 a well founded world wide sales force. Money It is expensive to develop new products.,4,RISC changes name to AVR,Bogen and Wollan makes a deal with Atmel on further development and sales of the RISC Extensive development is put into t

5、he RISC and they change the name to AVR The agreements target is to establish a yearly revenue of AVR products of $100mil within 5years As a part of the agreement they establish Atmel Norway Atmel Norway gets the main responsibility to developand market the AVR microcontrollers The first AVR is rele
