A microcontroller is a
small computer on a single integrated circuit containing a processor core,
memory, and programmable input or output peripherals. Neither 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 microprocessors used in personal computers or other general
purpose applications. Microcontrollers are used in automatically controlled
products and devices, such as automobile engine control systems, implantable
medical devices, remote controls, office, machines, appliances, power tools,
and toys. By reducing the size and cost compared to a design that uses a
separate microprocessor, memory, and input/output devices, microcontrollers
make it economical to digitally control even more devices and processes. Mixed
signal microcontrollers are common, integrating analog components needed to
control non-digital electronic systems. In this project the PIC16F877A are used
and Table 1 indicated devices features.
