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 major component of this circuit is Microchip’s SST89E54RDA-40-C-PIE, which is a pin-for-pin compatible with typical 8051 microcontroller devices. It has a built-in timer used to produce accurate ...

In life and embedded systems timing is everything. Give [Frank’s] web-based timer calculator a try. Set your system clock resolution (in hertz making sure you account for any system clock divider), ...

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 ...

The 8051 is alive and well. Cygnal Integrated Products has crammed a 25-MHz 8051 core, 8 kbytes of flash, and 256 bytes of data RAM into a tiny 11-pin, 3- by 3-mm (9 mm2) micro-lead package (MLP).

Boasting of a 50x performance gain over original 8051 microcontrollers and a six-fold gain over the next-fastest 8051s, the DS89C420 is said to be the first 8051-compatible controller to achieve peak ...

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 ...
