Embedded technology:8051 Microcontroller

The Intel 8051 is an 8bit microcontroller which means that most available operations are limited to 8 bits. There are 3 basic"sizes" of the 8051: Short, Standard, and Extended. The Shortand Standard chips are often available in DIP (dual inline package) form, but the Extended 8051 models often have a different form factor, and are not "dropin compatible".
All these things are called 8051 because they can all be programmed using 8051 assembly language, and they all share certain features(although the different models all have their own special features). The success of the Intel 8051 spawned a number of clones which are collectively referred to as the MCS51 family of microcontrollers, which includes chips from vendors such as
Atmel, Philips, Infineon, and Texas Instruments.8051 block diagram

Samsung has worked in this phone by putting their wheels on the shoulder, they are in a full mood to compete with the new Apple I Phone 4S, to compete with Apple, Samsung has built a new feature in Galaxy Note, An unusual feature for such a device is a built-in stylus, which is called the "S" pen, The Stylus is tucked into the bottom panel of the phone, it is like the pen and phone will be working as a paper on which u can write and share the written content. one more thing i'd like to add and that is the stylus which can replace the finger when the precision is needed.
