The 80C186EC is a member of the 186 Integrated Processor Family. The 186 Integrated Processor Family

incorporates several different VLSI devices all of which share a common CPU architecture: the 8086/8088.

The 80C186EC uses the latest high density CHMOS technology to integrate several of the most common

system peripherals with an enhanced 8086 CPU core to create a powerful system on a single monolithic

silicon die.
