Title:
DATA TRANSMISSION CIRCUIT, DATA TRANSMISSION SYSTEM, AND CONTROL METHOD OF DATA TRANSMISSION CIRCUIT
Document Type and Number:
Japanese Patent JP2017207963
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce the number of wirings in a system in which data is transmitted between different power supply domains.SOLUTION: A transmission side buffer starts, at start timing, a process of sequentially selecting a plurality of transmission side buffer regions and retaining transmission data in the selected regions for a prescribed time. A voltage conversion unit performs voltage conversion of the retained transmission data and outputs resultant data as reception data. A reception side buffer starts a process of sequentially selecting a plurality of reception side buffer regions and retaining the reception data in the selected regions for a prescribed time at timing when a delay time less than the prescribed time has elapsed since the start timing.SELECTED DRAWING: Figure 3
