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 ...

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.

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.

A new 16-bit 80251 microcontroller IP core shipping now from CAST, Inc. runs 69.7 times faster than the original 8051 chip, making it the highest performance MCS51 instruction set compatible IP core ...

Many will tell you that 8-bit microcontrollers are dead. Not so. Silicon Labs' latest 8051-based EFM8 microcontrollers highlights why that is not the case. The EFM8 “Bee” series is divided into three ...

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 ...

Silicon Labs has built a family of 8bit microcontrollers around its 8051-based CIP-51 core, running at 50MHz. “The BB5 family supports voltage options from 1.8 to 5.5V, allowing them to last for years ...

This 8051 IP core implements a range of fast, 8-bit, 8051-compatible microcontrollers that execute the MCS®51 instruction set. The R8051XC2 IP core ...

Adding to the SuperFlash-based FlashFlex family of eight-bit, 8051-compatible microcontrollers, the SST89V54RD-33-C-QIF is available in a 6 mm x 6 mm x 0.8 mm WQFN package standing 0.7 mm in height, ...
