FlashRunner™ In-System Programmer (ISP) line from SMH Technologies supports 8051s from CAST; Live 8051 programming demo running in CAST’s DAC booth Woodcliff Lake, NJ, USA and Villotta di Chions, ...

Suppose for a moment that you're an engineer designing a new 8051-based product. Not unexpectedly, the application's code size will greatly exceed the 64KB architectural limit of the 8051's program ...

Imagine you’re stuck on a desert island, hundreds of miles away from the nearest person, and you finally have time to finish that project you’re working on. You have a single microcontroller, but ...

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 ...

Microchip Technology has introduced the MPLAB PICkit Basic, an affordable and versatile in-circuit debugger designed to simplify programming and debugging for engineers, hobbyists, and students. The ...

Here we designed a simple non contact tachometer using microcontroller which can measure speed with an accuracy of 1 rev/sec. Here we design a simple non-contact tachometer using microcontroller, ...

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.

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, ...
