描述 Description

IEBus? (Inter Equipment Bus?) PROTOCOL CONTROL LSIDESCRIPTION
The μPD6708 is a peripheral LSI for microcontrollers that controls the protocol of the IEBus.
This LSI 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
?? (communication between one unit and multiple units)
? Choice of three modes with different transmission speeds
? On-chip IEBus driver/receiver
? Transmit/receive buffer
?? Transmit: 4-byte FIFO
?? Receive: 20-byte FIFO
? Interface with microcontroller
??
? Three-line serial I/O (SCK, SO, SI pins)
??
? Transfer with MSB first
? Oscillation frequency (fX): 12 MHz, 12.58 MHz
??
? In modes 0 and 1: ±1.5 %
??
? In mode 2: ±0.5 %
? Supply voltage: VDD = 5 V ±10 %APPLICATION FIELD
?? Fields where a small-scale digital data transfer system is required
?? between equipment, such as automobile electronicsystems and industrial equipment
