Toshiba Electronic Devices & Storage Corporation will provide samples of ” TB9032FNG “, a vehicle-mounted A driver/receiver integrated circuit (IC) for the physical layer interface defined in the Clock Extension Peripheral Interface (CXPI)  automotive communication protocol standard.
As the trend towards vehicle electrification continues to increase, the number of electronic components in in-vehicle systems increases, leading to increased system complexity and increased vehicle weight as manufacturers incorporate more wiring harnesses into their designs. To solve this problem, it is necessary to change the connection method of the current system (Human-Machine Interface (HMI)  connects switches and sensors in a one-to-one manner) and reduce the amount of wiring harness by multiplexing in-vehicle communication.
The HMI integrates an Area Network (CAN)  and a Local Interconnect Network (LIN)  ; the former is more costly and the latter less responsive. CXPI is a set of in-vehicle communication protocols developed in Japan and has been adopted by international standards. CXPI includes an in-vehicle sub-network that costs less than CAN and responds faster than LIN.
The TB9032FNG combines a motor driver IC and CXPI communication, and provides a network interface for in-vehicle applications or an interface to an area electronic control unit (ECU)  , which can support control functions such as door lock control and rearview mirror control.
The new product can switch modes between command nodes and response nodes through an external terminal. In addition, it has a current consumption (sleep mode) (I BAT_SLP ) of 5 μA (typ.)  and low current consumption in standby mode. It is also equipped with fault detection functions, including over-temperature detection and low-voltage detection, and is available in the P-SOP8-0405-1.27-002 package.
The product has an operating temperature range of -40°C to 125°C and is designed to meet the AEC-Q100 (Grade 1) qualification standard for automotive electronic components.
Toshiba plans to use its leading CXPI physical layer technology assets to develop an interface IC that will integrate a CXPI controller and protocol control hardware.
