Automotive Network Communication

The platform configuration of automotive network communication has been changing because motor vehicles are rapidly becoming electrified and digitalized. Toshiba offers automotive network communication devices that meet the needs of the times. The automotive communication protocol standard CXPI has a high-speed response suitable for networks of automotive body system applications such as steering switches, light switches etc. or interfaces of zone ECUs. Moreover, its multiplex communication brings about reduction of the number of wiring harnesses, helping to reduce vehicle body weight.

What is CXPI?

CXPI(Clock Extension Peripheral Interface) is an international standard (ISO 20794) for automotive communication protocols.
This standard which provides a multiplex communication method was established for next-generation automotive sub-networks to bring about reduction of the number of wiring harnesses of HMI(Human Machine Interface) devices, helping to reduce vehicle body.
CXPI is superior to LIN in terms of two-way communication between a commander and responders, large-capacity data transfer, and high-speed response.
