Semiconductor Bridge Circuit for Mixed-Protocol Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semiconductor devices face challenges in accommodating different communication protocols, leading to increased wiring and costs due to the need for multiple CAN transceivers when integrating devices with varying communication protocols.
Innovation Solution
A semiconductor device with integrated bridge functions allows for simultaneous communication with devices using different protocols by employing additional terminals and a control section that manages data conversion and protocol translation, reducing the number of required transceivers and wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple CAN transceivers are used to accommodate devices with different communication protocols, then communication compatibility is improved, but wiring complexity and costs increase
Solution Approach 1:
The patent combines multiple communication protocols (CAN and LIN) into a single transceiver device. The transceiver includes multiple communication interfaces that can operate with different protocols simultaneously, eliminating the need for separate transceivers for each protocol and reducing wiring complexity
Solution Approach 2:
The transceiver is designed with multi-functionality to support both CAN and LIN communication protocols through a single device. It includes multiple communication interfaces (first communication interface for CAN, second communication interface for LIN) that can be selectively activated based on the connected device's protocol requirements
2Adaptability or versatility
If multiple CAN transceivers are used to support different communication protocols, then protocol diversity is improved, but the number of required transceivers and costs increase
Solution Approach 1:
The transceiver incorporates multiple communication interfaces within a single device, enabling it to function as both a CAN transceiver and a LIN transceiver. This universal design reduces the quantity of transceivers needed while maintaining support for multiple protocols
Solution Approach 2:
The patent merges the functionality of separate CAN and LIN transceivers into one integrated device. The transceiver includes a first communication interface configured for CAN communication and a second communication interface configured for LIN communication, consolidating what would traditionally require two separate devices

AI summary
In a semiconductor device, when bridge selection data included in reception data indicates an on-state of a through-output in which bit data is output as is, data for a first device included in the reception data is through-output from a second output terminal; transmission data received by a second receiving section via a second input terminal during the through-output of the reception data is stored in a buffer; and the transmission data read from the buffer after the through-output of the reception data is output via a first output terminal by a second transmitting section.
