Product Summary

The KU80C188EC20 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 KU80C188EC20 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.
