The intel 8051 series 8bit microcontroller, originally introduced in 1980, remains popular and has had perhaps the longest product life of all such devices. It has become the industry standard for ...

This paper describes the design and implementation of a version of the 8051 microcontroller, one of the most commercially used microcontrollers in FPGA with reconfigurable instruction set.

Although 8051-compatible microcontrollers with SPI ports are available, a lower-cost device with an SPI port bit-banged through GPIO pins often suffices. The code shown here takes advantage of ...

Let’s say you’re working on a project, and you need a microcontroller. Which chip do you reach for? Probably the one you’re most familiar with, or at least the one whose programmer is hiding away in a ...

Structure and timing of typical microprocessors. Sample microprocessor families. Memories, UARTS, timer/counters, serial devices, and related devices. MUX and related control structures for building ...

A while back, [Matt] bought a few 8051 MCUs and tucked them away for a future project. He just found these fabulous little chips in a component drawer and decided it was time to figure these guys out.

Characteristics and contrasts with microprocessors. Hints on selecting and deploying microcontrollers. What might be on the horizon for microcontrollers, especially the competition between Von Neumann ...

Extending the company's FRAM-enhanced microcontroller offerings, the VRS51L3174 debuts as an 8051-based MCU with 8 KB of nonvolatile FRAM that drops into industry-standard 44-pin QFP sockets. Features ...

An open-source ecosystem allows sharing application resources and providing technical support through an active developers’ community. OpenPLC is a programming editor that support the International ...
