DESCRIPTION
The
μ
PD6708 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
μ
PD6708 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
At 12 MHz
At 12.58 MHz
Mode 0
Approx. 3.9 Kbps
Approx. 4.1 Kbps
Mode 1
Approx. 17 Kbps
Approx. 18 Kbps
Mode 2
Approx. 26 Kbps
Approx. 27 Kbps
