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, ...

Microprocessor is the Central Processing Unit (CPU) of embedded system. It does arithmetic and logic operations of the digital binary data.Very old embedded systems circuit/board was generally made up ...

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 ...

Here, we explain about how to interface 16×2 LCD module to AT89C51 which is a 8051 family microcontroller and also we provide the code in C language which is working fine without any errors. Here, we ...

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.

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 ...

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 ...

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 ...
