TOSHIBA TO OFFER SAMPLES OF CLOCK EXTENSION PERIPHERAL INTERFACE DRIVER/RECEIVER IC

KUALA LUMPUR, March 16 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (Toshiba) will start to provide test samples of “TB9032FNG”, an automotive driver/receiver Integrated Circuit (IC) for the physical layer interface defined in the Clock Extension Peripheral Interface (CXPI), the standard for automotive communications protocols.

The electrification of automobiles is increasing the number of electronic components in automotive systems, adding to their complexity, and also to vehicle weight, as more wiring harnesses are required.

The solution to this issue lies in changing the current system, where a human machine interface (HMI) connects switches and sensors in a one-to-one manner, for a system that uses multiplex transmission in-vehicle communications to reduce wiring harnesses.

According to Toshiba in a statement, HMI integrates a controller area network (CAN) and a local interconnect network (LIN), whereby the former is costly, the latter lacks responsiveness.

Meanwhile, CXPI, the in-vehicle communications protocols developed in Japan, now adopted as an international standard, includes in-vehicle subnetworks that cost less than CAN and that are more responsive than LIN.

TB9032FNG combines Motor Driver IC and CXPI communications, and is provided as a network interface for in-vehicle body applications or as an interface for zone electronic control units.

The new product can be switched between commander node and responder node via an external terminal, and equipped with fault detection functions that include overheat detection and low voltage detection.

Toshiba plans to use the CXPI physical layer technical assets it has cultivated to develop an interface IC that also integrates the CXPI controller and the protocol-control hardware.
