At the introduction of the 12,000 gate 32bit ARM Cortex M0 recently, an ARM spokesman told EW the M0 was close to the 10,000 gates normally occupied by the 8bit 8051 microcontroller. Inspired by this, ...

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 was an 8-bit Harvard-architecture microcontroller first put out by Intel in 1980. They’ve since discontinued that line, but it lives on in the low-cost STC8 family of chips, which is ...

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 ...

Montreal—Goal Semiconductor says its VERSA families of flash 8051 microcontrolles are now available from stock to 4-weeks. According to Goal, industry-wide lead times now range from 12 to 30 weeks.

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 ...
