PURPOSE OF 8052.COM
This web site is dedicated exclusively to the 8052 mirocontroller, related products (both hardware and software), and 8052 derivative chips. This includes the traditional 8052, 8051, 8032, and 8031 along with more modern derivatives such as the Atmel AT89S8252, and many derivatives by Silicon Laboratories, Philips, and many others.
This site is divided into a number of sections, each of which can be selected by clicking on the corresponding label on the left-hand side of your screen. We have a tutorial section for the programmer or student that is just learning about the 8052 microcontroller. We have a reference section for the proficient developer who just needs to access some quick reference information. We also have an entire code library in which you may find the code you need to write already written and ready to use. We have links to other quality 8052 sites that may be able to supplement the information on this site.
