Automotive CXPI Communication Application Circuit A (Driver-Receiver Board / CXPI Commander Node)

CXPI, a next‑generation automotive communication protocol, delivers low cost and high responsiveness to support efficient control of various in‑vehicle functions.
This reference design implements a CXPI driver/receiver circuit for in-vehicle CXPI communication.
The CXPI driver/receiver IC TB9032FNG is used as the communication interface.
When combined with a host controller equipped with a CXPI controller, the system operates as a CXPI commander node, enabling reliable connectivity to the CXPI bus.
