How many data types does 80286 support?
As we have already mentioned earlier that it is a 16-bit microprocessor thus holds a 16-bit data bus and 24-bit address bus. Also, unlike the 8086 microprocessor, it offers non-multiplexed address and data bus, which increases the operating speed of the system.

What does Intel 8286 do?
When Intel 8287/8286 octal bus transceiver is used this signal controls the direction of data flow through the transceiver. When it is HIGH, data is sent out. When this signal is HIGH, the CPU wants to access memory. When this signal is LOW, the CPU wants to access I/O device.
What kind of microprocessor is the 80286?
80286 Microprocessor is a 16-bit microprocessor that has the ability to execute 16-bit instruction at a time. It has non-multiplexed data and address bus. The size of data bus is 16-bit whereas the size of address bus is 24-bit. It was invented in February 1982 by Intel. 80286 microprocessor was basically an advancement of 8086 microprocessor.
What was the addressability of the Intel 80286?
The Intel 80286 had a 24-bit address bus and was able to address up to 16 MB of RAM, compared to the 1 MB addressability of its predecessor.
What was the first 16 bit Intel processor?
Intel 80286. The Intel 80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bit microprocessor that was introduced on February 1, 1982. It was the first 8086-based CPU with separate, non-multiplexed address and data buses and also the first with memory management and wide protection abilities.
What is the central processing unit of 80286?
The CPU, central processing unit of 80286 microprocessor, consists of 4 functional block: Firstly, the physical address from where the data or instruction is to be fetched is calculated, by the address unit. Once the physical address is calculated then the calculated address is handed over to the bus unit.
