Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transceivers and complex interconnects are used to support different communication protocols, then protocol compatibility is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal communication interface that supports multiple communication protocols (CAN, LIN, MOST, FlexRay, Ethernet) through a single transceiver. The interface includes a protocol conversion unit that can dynamically switch between different protocols, allowing one device to communicate with various types of devices without requiring multiple dedicated transceivers. This multi-functional approach resolves the contradiction by maintaining protocol compatibility while reducing the number of transceivers and interconnects needed.
Solution Approach 2:
The patent introduces a protocol conversion unit as an intermediary component between the communication interface and the data bus. This intermediary translates and converts data between different communication protocols, enabling seamless communication between devices with different protocols through a single transceiver. The protocol conversion unit acts as a mediator that handles protocol differences without requiring multiple dedicated transceivers, thus reducing system complexity while maintaining compatibility.

Solution Approach 2:
The patent merges multiple protocol-specific transceivers into a single integrated transceiver that can handle multiple protocols. By combining the functionality of separate transceivers into one unified interface with protocol conversion capabilities, the patent reduces component count and manufacturing cost while maintaining the ability to support various communication protocols. This consolidation directly addresses the cost issue while preserving protocol compatibility.

AI summary
In the semiconductor device, when bridge select data contained in received data indicates on status of through output of bit data, i.e. output of bit data as it is intact, between a first bus and a second bus, first device-dedicated data contained in the received data is through-outputted to the second bus, and moreover, when the bridge select data indicates on status of the through output and when communication by a specified second serial communication method dedicated to the first device has been set to the semiconductor device, a clock signal synchronized with the through-outputted data as well as a chip select signal are outputted.
