功夫不负有心人人啊，终于在Wiki上找到点Atmel的历史：http://en.wikipedia.org/wiki/Atmel
Atmel Corporation was founded in 1984 and is based in San Jose, CA.
Atmel introduced the first 8-bit flash microcontroller in 1993, based on the 8051 core.[3]
In 1996, a design office was started in Trondheim, Norway, to work on the AVR series of products.
In March 2008, Atmel acquired Quantum Research Group ('QRG') located near Southampton England, in order to gain entry into the capacitive touch button and touch screen market. Founded by Hal Philipp in 1996, QRG focused on using standard microcontrollers pre-programmed as touch sensors, including devices sourced from several companies including Atmel. In acquiring QRG, Atmel also gained a substantial patent portfolio and customer list related to touch sensing. Of particular note are patents relating to touch screens using mutual capacitance, matrix-based sensing topologies. In acquiring QRG, Atmel also inherited an ongoing patent lawsuit that QRG had filed against Apple Inc. in 2005 alleging infringement of one of its charge-transfer based patents in the iPod click-wheel; the case was later settled. The acquired business unit still operates near Southampton UK. Today, QRG-based capacitive touch solutions using AVR microcontrollers form a large part of Atmel's product marketing efforts.
不过这点内容还是比较笼统，我是希望找到更为详细的信息：
1993年推出的是哪一款51内核的芯片呢？
AT89C51推出的时间应该更早吧！
