8051 Microcontroller Family
The 8051 has been available since the early 1980’s. With a wide variety of outstanding features and peripherals, the 8051 CPU core is destined to see service well into the next century. More than 200 different 8051 derivatives are available today from a variety of chip vendors. More than half of all embedded projects with a CPU use members of the 8051 embedded processor, the 8051 has no equal. A typical 8051 family member contains the 8051 CPU core, data memory, code memory, and some versatile peripheral functions. A flexible memory interface lets you expand the capabilities of the 8051 using standard peripherals and
