TEXT 2
A MICROCONTROLLER
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 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, toys and other embedded systems. By reducing the size and
cost compared to a design that uses a separate microprocessor,
