The 8051-compatible microcontrollers are equipped with up to two inputs that may be used as general-purpose interrupts. A simple way to increase the number of interrupt inputs is shown in the figure.

📌 8051 Interrupts – Description An interrupt is a mechanism by which the 8051 microcontroller can temporarily halt its main program to execute a special routine (called Interrupt Service Routine – ...

In designing µC-based systems, you often face a situation in which the µC has to respond to an external event happening at an uncertain moment in time. One example is receiving an echo from an object ...

The 8051 is an accumulator-based design with 255 instructions. A basic instruction cycle takes 12 clocks; however, Dallas Semiconductor redesigned the instruction-execution circuitry to reduce 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 ...
