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 80868088

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
