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 ...

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 ...

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.

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 ...

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.

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, ...

Many will tell you that 8-bit microcontrollers are dead. Not so. Silicon Labs' latest 8051-based EFM8 microcontrollers highlights why that is not the case. The EFM8 “Bee” series is divided into three ...

Adding to the SuperFlash-based FlashFlex family of eight-bit, 8051-compatible microcontrollers, the SST89V54RD-33-C-QIF is available in a 6 mm x 6 mm x 0.8 mm WQFN package standing 0.7 mm in height, ...

Meet the Raspberry Pi Pico 2 W, a tiny board designed around a microcontroller that lets you build hardware projects at scale. Raspberry Pi is once again using the RP2350, its own well-documented ...
