There are three types of Microcontroller based on Bit configuration. Microcontroller Classification on the basis of Bit Configuration ![]() This architecture has separate Memory units for Program and Data Storage and separate Busses for transfer of data and instructions. This type of architecture has common Memory for storage of data and programs. 3 – Classification of Microcontroller Microcontroller Classification on the basis of Architecture This type of MC has all programs and Data Memory, Counters and Timers, Interrupts, I/O Ports embedded on the chip. This type of MC do not have a program memory on the chip. MC is further divided into two categories based on their Memory configuration. Microcontroller Classification on the basis of Memory Microcontrollers are broadly classified into various categories based on: 2 – 8051 Microcontroller Development Board Classification of Microcontroller They are popularly used for educational purposes to gain experience as they are available at low cost.įig. It provides necessary circuitry including Processor, Memory, Clock, I/O circuits etc. These features of Microcontrollers make it an ideal choice for embedded applications.įig.2 below shows Single-Board MC also called Development Board Microcontroller built onto a single Printed Circuit Board (PCB). MC’s operate at lower speeds, capable of retaining functionality and consume less power. They are available with on board Memory and I/O Ports which eliminates building a circuit that has separate external RAM, ROM and Peripheral chips. They are dedicated to execute specific task that is programmed and stored in ROM. Microcontrollers are also called as “special purpose computers”. It is also called MC or MCU (Microcontroller Unit) which is a compact digital processor on Metal-Oxide-Semiconductor Chip. ![]() ![]() Microcontroller is a device that captures the input, processes it and generates output based on the information captured. This post will discuss about what is Microcontroller, how it works, its various classifications, architectures, applications, advantages and disadvantages. Any technological device around us is built with a Microcontroller. Microcontrollers play an important role in the world of Embedded Systems.
