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.

The 8051 8-bit microcontroller just keeps plugging away, adding new peripherals, speed grades, and packaging. Among the latest advances is Dallas Semiconductor's 8051 implementation that delivers a ...

Bielsko-Biala/Poland, May 24th, 2010 - The silicon intellectual property (IP) provider, Evatronix SA, today announced the R80251XC – the high performance 32-bit Intel 80C251 compatible ...

The 8-bit C8051F064/5/6/7 microcontrollers are offered as the first to integrate a 25-MIPS 8051 MCU with dual 16-bit 1-Msample/s A/D converters (accurate to ±0.75 LSB). According to the company, the ...

In this installment of Scope Noob I’m working with Direct Digital Synthesis using a microcontroller. I was pleasantly surprised by some of the quirks which I discovered during this process. Most ...
