MOS INTEGRATED CIRCUIT
µPD72042A, 72042B
LSI DEVICES FOR Inter Equipment BusTM (IEBusTM) PROTOCOL CONTROL
The µPD72042A and µPD72042B are microputer 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 microputer 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 munication...
