Toshiba successfully introduced the TB9033FTG responder interface integrated circuit, becoming the first product to comply with the CXPI specification. Its built-in advanced hardware logic design, improve signal reception efficiency and shorten the development schedule. The TB9033FTG has the advantages of fault detection, temperature range up to -40°C to 125°C, and optimizes the body control system, showing great market potential.

     Toshiba successfully introduced the TB9033FTG responder interface integrated circuit, becoming the first product to comply with the CXPI specification. Its built-in advanced hardware logic design, improve signal reception efficiency and shorten the development schedule. The TB9033FTG has the advantages of fault detection, temperature range up to -40°C to 125°C, and optimizes the body control system, showing great market potential. In the future, Toshiba will launch the TB9032FNG to further promote automotive communication technology innovation.

     Today, we take an important step in the automotive electronics industry by announcing the successful launch of the TB9033FTG responder interface integrated circuit, the industry's first innovative product (IC) compliant with the CXPI(Vehicle Clock Peripheral Interface) specification. The introduction of this IC means that Toshiba has achieved a leading position in promoting the standardization of vehicle communication protocols.

     The TB9033FTG stands out because of its built-in advanced hardware logic design, which can handle efficient signal reception directly based on the CXPI protocol and generic input/Export (GPIO) interface. The highlights of the design not only avoid the complexity and cost of developing dedicated software, but also significantly shorten the development schedule of vehicle-related products, providing greater efficiency and flexibility for automakers and suppliers.

     The TB9033FTG comes with a rich set of pins and features in the technical specification, including 16 GPIO pins, six of which can be flexibly configured as BSC119N03SG analog to digital converter (AD) inputs and four suitable pulse-width modulation (PWM) outputs. In addition, it integrates a variety of features to enhance automotive applications such as input supervision in sleep mode, maximum 4x4 switch matrix input function, automatic implementation of safe export countermeasures in case of communication interruption, further improving overall stability and safety.

     In terms of stability, the TB9033FTG has an advanced fault detection system built in, which can detect and respond to abnormal situations such as overheating, overvoltage and undervoltage in real time. What's more, it can also capture critical data before a failure occurs and immediately transmit it to a comprehensive command node, providing valuable information applications for rapid fault location and treatment, significantly improving fault prevention and handling capabilities for automotive applications.

     The TB9033FTG has a temperature range of -40°C to 125°C for the rigorous vehicle operating environment, fully meeting the high standards required for automotive electronics. At the same time, the IC will also be fully compliant with the AEC-Q100 automotive electronic reliability testing standard, further ensuring its efficient operation in a variety of complex situations.

     The TB9033FTG also shows great potential in optimizing the structure of the body control system, a multiplexing technology suitable for vehicle communication. The system can significantly reduce the number of wire harnesses required for the system, which not only helps to reduce the overall net weight of the vehicle, but also improves the compactness of customization and the cost efficiency of manufacturing.

     Looking ahead, Toshiba also said that the TB9032FNG drive receiver IC is another upcoming CXPI communication product for vehicles. The new IC will leverage its external pin design to flexibly switch roles between the command node and the response node, providing a more flexible variety of device options for automotive communication systems. This series of innovative measures will undoubtedly further consolidate Toshiba's leading level in the field of automotive electronics and promote the development of the industry in a more efficient and intelligent direction.
