Through the use of CXPI, multiplexing across ECUs is made possible, resulting in a decrease in the weight of the vehicle and an increase in fuel efficiency.
Additionally, it is possible to establish low-power, high-reliability CXPI communication thanks to low quiescent current (3 A typ.) and high ESD resistance (8 kV, IEC61000-4-2).
Many systems use LIN for multiplex communication to reduce weight. However, when multiplexing in real-time HMI (Human Machine Interface) applications like wipers, lights, and steering switches, it is challenging to provide acceptable dependability and communication response.
In response, the next-generation automotive communication protocol CXPI (Clock Extension Peripheral Interface) was created to enable multiplexing even in sophisticated, multifunction HMI systems, therefore reducing the quantity and weight of wiring harnesses.
The Global Automotive CXPI Transceiver market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Recently, ROHM announced the availability of a transceiver IC for use in body control applications, such as steering switch, AC, and instrument panel systems, that is compatible with the new low-speed, low-cost CXPI communication protocol.
By lowering the number and size of wiring harnesses, the BD41000FJ-C facilitates multiplexing across ECUs, resulting in a decrease in vehicle weight and an increase in fuel efficiency.
Achieving low-power, high-reliability CXPI communication is also made possible by low quiescent current (3uA typ.) and high ESD resistance (8kV, IEC61000-4-2).
It has been vital in recent years to minimise system power consumption through electronic management as well as reduce vehicle weight by adopting lighter components, including wiring harnesses, due to the ongoing demand for higher fuel efficiency.
