Toshiba Electronic Component and Storage Device Co., Ltd. ("Toshiba") announced today that the launch of an interface drive / receiver IC --- "TB9032FNG", which is a clock expansion peripheral interface (CXPI) [1]The car driver / receiver IC of the physical layer interface defined in the vehicle communication protocol standard.The sample application of this product will begin this month.

The electrification trend of cars has pushed the rising number of electronic components in the vehicle system, which not only increases the complexity of the device, but also increases the self -weight of the vehicle as the manufacturer adopts more wire beams in the design.The solution of this problem is to change the current system, that is, the human -machine interface (HMI) [2] connect the switch and sensor in one -to -one way, and reduce the amount of line beam in the way of transmitting communication in the multi -way transmission vehicle.

HMI usually integrates the regional network (Can) [3] and the LAN network (Lin) [4], while the former costs high, but the latter has poor response ability.CXPI is a set of Japanese -developed vehicle communication protocols that have been adopted by international standards. CXPI contains a vehicle sub -network that costs lower than CAN and responds higher than Lin.

The TB9032FNG combines the electrical control device (MCD) and CXPI communication, and provides the interface of the network interface or regional electronic control unit (ECU) of the vehicle application [5].It supports functions such as control door locks and rearview mirror control.

New products can be switched between the mode between the instruction node and the response node through the external terminal.In addition, it has 5 μA (typical value) current consumption (sleep) (IBAT_SLP) [6], and the standby mode consumes low current.In addition, it is also equipped with fault detection functions, including overheating and low voltage detection, and uses P-SOP8-0405-1.27-002.

The operating temperature range of this product is -40 ° C to 125 ° C, and the design meets the verification standards of AEC-Q100 (level 1) vehicle electronic components.

Toshiba plans to use its leading CXPI physical layer technical assets to develop an interface IC, which will integrate CXPI controllers and protocols to control hardware.
