Description: 8051架构单片机元件库。
Protel一直以来都没有提供Atmel公司8051架构单片机的元件库，电子爱好者和工程师们都得用其它公司8051架构单片机元件库来代替或者自己制作元件库。
根据Atmel公司官方网站(http://www.atmel.com)提供的Datasheet文件制作了一个Atmel公司8051架构单片机元件库。-8051 single-chip architecture libraries. Protel has failed to provide Atmel Corporation 8051 MCU architecture libraries, electronic enthusiasts and engineers had to use other companies Singlechip 8051 framework libraries to replace or produce their own libraries. According to the official website of Atmel Corporation (http://www.atmel.com) provided Datasheet paper produced a single-chip Atmel Corporation 8051 framework libraries.
