80286

The 80286 is a 16-bit microprocessor released by Intel in 1982, succeeding the 8086 and serving as the basis for the IBM Personal Computer AT. It was the first microprocessor to incorporate memory management and protection features, and was significantly faster than its predecessors.

What does 80286 mean?

The 80286, also known as the i286, is a 16-bit microprocessor Chip that was released by Intel in 1982. It is an enhanced version of the earlier 8086 chip, and it features a number of improvements, including a faster clock speed, a larger Address space, and more advanced instructions. The 80286 was a popular choice for personal computers in the mid-1980s, and it is still used in some embedded systems today.

The 80286 is a complex chip that contains over 130,000 transistors. It is fabricated using a 3-micron process, which means that the features on the chip are very small. The chip is packaged in a 68-pin ceramic DIP (Dual in-line package).

The 80286 has a clock speed of 6 MHz or 8 MHz. It has a 16-bit data bus, which means that it can Transfer 16 bits of data at a time. The 80286 also has a 20-bit address bus, which means that it can access up to 1 MB of memory.

The 80286 includes a number of advanced instructions that are not found on the 8086. These instructions include the MUL (multiply) and DIV (divide) instructions, which can be used to perform complex mathematical operations. The 80286 also includes a number of floating-point instructions, which can be used to perform calculations on real numbers.

The 80286 is a powerful microprocessor that was used in a wide variety of applications. It is still used in some embedded systems today, and it is an important part of the history of computing.

Applications

The 80286 was used in a wide variety of applications, including personal computers, workstations, and embedded systems. In personal computers, the 80286 was used in the IBM PC AT and the Compaq Deskpro 386. These computers were used for a variety of tasks, including word processing, spreadsheets, and database management.

In workstations, the 80286 was used in the Sun-3 and the Apollo DN3000. These workstations were used for a variety of tasks, including computer-aided design, engineering, and scientific Research.

In embedded systems, the 80286 is still used in a variety of applications, including industrial control, medical equipment, and telecommunications equipment. The 80286 is well-suited for these applications because it is a powerful and reliable chip that can be easily integrated into a variety of systems.

History

The 80286 was developed by Intel in the early 1980s. The chip was designed to be a more powerful and versatile version of the earlier 8086 chip. The 80286 was released in 1982, and it quickly became a popular choice for personal computers and workstations.

The 80286 was a major improvement over the 8086. The 80286 had a faster clock speed, a larger address space, and more advanced instructions. The 80286 also included a number of new features, such as protected mode and virtual memory.

Protected mode is a feature that allows the 80286 to run multiple programs at the same time. Virtual memory is a feature that allows the 80286 to access more memory than is physically installed on the computer. These features made the 80286 a much more powerful and versatile chip than the 8086.

The 80286 was a major success for Intel. The chip was used in a wide variety of applications, and it helped to establish Intel as a leader in the microprocessor industry. The 80286 is still used in some embedded systems today, and it is an important part of the history of computing.
