General Description

The UM82C206 Integrated Peripheral Controller includes two 8237 DMA controllers, two 8259 interrupt controllers, one 8254 timer/counter, one MC146818 compatible real time clock,an additional 64 bytes CMOS RAM, one 74LS612 memory mapper, and some top level decoder/configuration logic circuits.

It is a single chip integration of all main peripheral parts attached to the X bus of PC/AT architecture.

While providing full compatibility with PC/AT architecture, the UM82C206 also offers some enhanced
