ATMEL 8051 Flash Based-Microcontroller Programmer

Posted on Aug 23, 2012

The Atmel Flash devices are ideal for developing, since they can be reprogrammed easy and fast. If you need more code space for your application, particularly for developing 89Cxx projects with C language. Atmel offers a broad range of microcontrollers based on the 8051 architecture, with on-chip Flash program memory.
