µPD6708
Overview
The µPD6708 is a peripheral IC for microcontrollers that controls the protocol of the IEBus.
This IC processes the protocol of the IEBus. Because it is provided with a transmit/receive buffer, the microcontroller can concentrate on the application processing of the IEBus. Because the µPD6708 also contains an IEBus driver/receiver, it can be directly connected to the bus.
Features
- Protocol control of IEBus
- Multi-master system
- Broadcast communication function (commu-nication between one unit and multiple units)
- Choice of three modes with different trans-mission speeds
