What are the differences between 80186 and 80286 microprocessor?

80126	80286
(i) The Intel 80186, is a microprocessor and microcontroller introduced in 1982.	(i) The Intel 80286 is a 16-bit microprocessor that was introduced on 1 February 1982.
(ii) Also known as the iAPX 186 or just 186.	(ii) It also marketed as the iAPX 286 and often called lnte1 286.
(iii) In 80186 the controller chip is set in the microprocessor by inter.	(iii) In 80286 the controller chip is again separated from microprocessor.
(iv) It was based on the Intel 8086 and, like it, had a 16-bit external data bus multiplexed with a 20-bit address bus.	(iv) 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.
(v) The internal clock generator replaces the external 8284A clock generator used with the 8086 microprocessors. This reduces the component count in a system.	(v) The clock is provided by the 82284 clock generator, and the system control signals are provided by the 82288 system bus controller.
