488 THE x86 MICROPROCESSORS
History and Development
It was in 1982 that Intel introduced the 80186 family of embedded microprocessors. In 1987,
the second generation i.e., 80C186 which was a CMOS version with smaller geometry and an
enhanced feature set, was released, which was pin compatible with 80186. Later, the 80186 EB
was introduced with a static, stand-alone module, known as the 80C186 Modular core, in
which peripherals were redesigned with standard interfaces. e new 80C186 EB was the fi rst
to use this modular capability. e design trend was towards reducing power dissipation, which
is a key parameter for an embedded product. Other ...
