8051 Micro-controller

The 8051 architecture provides many functions like CPU(central processing unit),  RAM(random access memory), ROM (read-only memory), I/O (Input/Output), timer, interrupt logic. etc. Intel introduces 8051 microcontrollers in 1981. It is an 8-bit microcontroller. It is built with 40 pins DIP (dual inline package), 4kb of ROM storage (on-chip memory). We can also interface external memory […]

In this 8051 tutorial, we will learn the 8051 Pin Diagram and 8051 microcontroller Pin Description. Like other microcontrollers 8051 pin diagram also describes the functionality of each pin and help you to identify the ports and other pins. Pins of 8051 Microcontroller The Below image describes the Pin Diagram of 8051 with respect to 

In this article, we will explore how to interface an EEPROM with an 8051 microcontroller using the I2C protocol. In real-world applications, microcontrollers often come with a limited amount of internal memory. This limitation can become a significant bottleneck during project development, especially when persistent data storage is required. To overcome this, microcontrollers typically offer

Input and output devices are the important components of embedded system, we cannot imagine any embedded device without the input and output device, switch and led are the basic example of input and output device, so it is very important to understand the interfacing of the switch and led. Here we learn how to control
