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, ...

One of the fun things about “old school” computers is that it was fairly easy to get kids into programming them. The old Basic interpreters were pretty forgiving, and you could do some clever things ...

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.

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 ...

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 ...

Whether you are creating a small Internet appliance, some hardware instrumentation, data loggers or an army of autonomous robots to do your bidding, in numerous situations you need the flexibility of ...

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, ...

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 ...

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, ...
