DATA SHEET MOS INTEGRATED CIRCUIT µPD72042 LSI DEVICES FOR Inter Equipment BusTM (IEBus TM) PROTOCOL CONTROL The µPD72042 is a microcomputer peripheral LSI device for IEBus protocol control. The µPD72042 performs all the processing required for layers 1 and 2 of the IEBus. The devices incorporate large transmission and reception buffers, allowing the microcomputer to perform IEBus operations without interruption. They also contain an IEBus driver and receiver, allowing them to directly connected to the bus directly. FEATURES • Control of layers 1 and 2 of the IEBus protocol • Support of a multi-master scheme • Broadcast function • Two communication modes having different transmission speeds can be selected.
