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 ...

The DQ8051CPU is an ultra high performance, speed optimized soft core of a single-chip 8-bit embedded controller, designed to operate with fast (typically on-chip) and slow (off-chip) memories. The ...

Woodcliff Lake, NJ, January 28, 2014 -- An 8051-compatible microcontroller core with 26.85 times the performance per MHz of the original 8051 chip is now available from semiconductor intellectual ...

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 ...

In this paper the authors give a novel idea about the design and implementation of a microcontroller based pulse counter. Intel 8051 is used as the main microcontroller unit and the system has been ...

With a peak performance of 100 MIPS, the C8051F120 microcontroller (MCU) family claims to be the industry's highest performance devices to date. In addition to the 100-MIPS 8051 CPU, the devices ...

There are rumors of a cheap chip that does USB natively, has an Open Source toolchain, and costs a quarter. These aren’t rumors: you can buy the CH552 microcontroller right now. Surprisingly, there ...

Deep in the heart of your latest project lies a little silicon brain. Much like the brain inside your own bone-plated noggin, your microcontroller needs protection from the outside world from time to ...
