This project implements an alphanumeric keypad, similar to the ones found in mobile phones, using an 8051 microcontroller. The system allows users to input alphanumeric characters and provides a ...

This is a simple password based door locking system circuit designed using 8051 microcontroller. It provides control to the actuating the load. It is a simple embedded system with input from the ...

Abstract: In this paper, we present the design of an asynchronous 8051 microcontroller with interface to external commercial memory. The design consists of an asynchronous core implemented using ...

Despite being 40 years old, 8051 microcontrollers can still serve useful roles in modern systems. But integrating 8051s in today's systems with their de facto standard AMBA® buses, wider datapaths, ...
