Toshiba Expands Range of Ethernet Bridge ICs for Automotive


Kawasaki, Japan : Toshiba Electronic Devices & Storage Corporation (“Toshiba”) adds the ” TC9563XBG ” (TC9563XBG) to its range of Ethernet bridge ICs for 10 Gbps communication in automotive information communications systems and industrial equipment Sampling has already started and mass production will start in August 2022.

This press release contains multimedia. View the full release here:

Automotive networks are evolving towards a zone architecture [1] , where communication between zones uses 1Gbps real-time, multi-gig [2] transmission at a rate of 1Gbps or higher via Ethernet. The new bridge IC features Toshiba’s first 2-port 10Gbps Ethernet, and the interface can be chosen from USXGMII, XFI, SGMII and RGMII [3] . Both ports support Ethernet AVB [4] and TSN [5] which enable sequential real-time processing and synchronous processing. They also support “simplified” SR-IOV (virtual functions) [6] . The combination of these features in the new product provides solutions that are optimized for the next generation of automotive networks.

As communications equipment continues to grow, the new ICs can be used not only for zone architectures, but also in various automotive uses such as IVI and telematics, and industrial equipment. It is also positioned to be the successor to the existing TC9560 and TC9562 series products that support 1Gbps Ethernet.

In recent years there has been an increasing number of devices adapted to PCIe interfaces for device-to-device communications such as Wi-Fi® and host SoCs tend to run less than PCIe interfaces. The TC9563XBG has three PCIe Gen 3 switch ports for communication with the host SoC and for connection to devices equipped with PCIe interfaces. The PCIe switch portion is configured with one 4-lane upstream port for connecting with the host SOS and two 1-lane downstream ports for connection to devices with a PCIe interface. Using a 3-port PCIe switch function for connections to such devices can help reduce the lack of a PCIe interface.

TC9563XBG (TC9563XBG), AEC-Q100 Grade 3 [7] will qualify.

[1] Zone Architecture: A network configuration expected to be used for the next generation of automotive networks. In this, a vehicle is divided into several parts and all these parts communicate with each other at high speed for aligned operation.
[2] Multi-Gig: Multi-Gigabit Ethernet (2.5Gbps to 10Gbps) Recent automotive networks require bandwidth of more than 1Gbps.
[3] USXGMII, XFI, SGMII, RGMII: Standard for Ethernet interfaces. USXGMII = Universal Serial 10 Gigabit Media Independent Interface; XFI = 10 Gigabit Serial Interface; SGMII = Serial Gigabit Media Independent Interface; RGMII = Reduced Gigabit Media Independent Interface.
[4] Ethernet AVB: IEEE802.1 Audio/Video Bridging. A standard for handling audio and video data using Ethernet standard technology.
[5] Ethernet TSN: IEEE802.1 time-sensitive networking. A standard for data transmission with lower latency than AVB.
[6] SR-IOV: Single Route I/O Virtualization. A standard that supports virtualization on PCIe devices.
[7] AEC-Q100 Grade 3: Testing standards formulated by the automotive industry to certify the reliability of ICs.
