Title : Microcontroller Intel 8051
Objectives : To know about microcontroller
Contents / Procedures :
A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input / output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessor used in personal computers or other general purpose applications.
Intel MCS-51 or 8051
The Intel MCS-51 is a Harvard Architecture, single chip microcontroller (µC) series which was developed by Intel in 1980 for use in embedded system.
Results / Analysis :
Overview of the 8051
