DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD72042A, 72042B  
LSI DEVICES FOR Inter Equipment BusTM (IEBusTM)  
PROTOCOL CONTROL  
The µPD72042A and µPD72042B are microcomputer peripheral LSI devices for IEBus protocol control.  
The µPD72042A and µPD72042B perform 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  
Microcomputer interface  
Three-/two-wire serial I/O  
• Transfer starting with MSB : µPD72042A  
• Transfer starting with LSB : µPD72042B  
Program crashes can be detected by means of a  
watchdog timer.  
• Two communication modes having different  
transmission speeds can be selected.  
When operating  
at 6 MHz
