I am just curious by very many people seem to be looking for circuits based on 8051 microcontroller.
Wy the applications bases on that particular very old microcontroller family have become very much asked for?
8051 is just a one of many microcontrollers that can be used for various controlling applications.
Here is a short description of 8051 microcontroller taken from this site on 8051 section:
"The 8051 is an 8 bit microcontroller originally developed by Intel in 1980. It is the world's most popular microcontroller core, made by many independent manufacturers. A typical 8051 contains CPU with boolean processor, 5 or 6 interrupts, 2 or 3 16-bit timer/counters, programmable full-duplex serial port, 32 I/O lines, RAM and ROM/EPROM in some models. The 8051 architecture is quite strange and original. One strong point of the 8051 is the way it handles interrupts. Vectoring to fixed 8-byte areas is convenient and efficient. The 8051 instruction set is optimized for the one-bit operations so often desired in real-world, real-time control applications. The 8051 has the widest range of variants of any embedded controller on the market. The smallest device is the Atmel 89c1051, a 20 Pin FLASH variant with 2 timers, UART, 20mA. The most powerful chip is the Infineon Technologies 80C517A, with 32 Bit ALU, 2 UARTS, 2K RAM, PLCC84 package, 8 x 16 Bit PWMs, and other features."
