Reports indicate that Toshiba Electronic Devices & Storage Corporation has introduced new Ethernet bridge ICs to expand its automotive product offerings. Apparently, the sample shipments for the new ICs would commence in February, while the volume production is scheduled to begin in October.

Further from the reports, the new TC9562 series consists of TC9562XBG which offers simpler IC configuration in comparison to the current products. Also, the new series has the TC9562BXBG which supports Ethernet AVB and Ethernet TSN and TC9562AXBG that offers more interfaces compared to the current bridge ICs of Toshiba’s TC9560 series.

The Ethernet AVB specification seemingly offers reliable data transmission in real-time and is increasingly utilized in vehicles. Currently, the Gigabit Ethernet (10/100/1000Mbps) solutions’ TC9560 series being offered by Toshiba is compliant with IEEE 802.1Qav and IEEE 802.1AS.

There are allegedly more road vehicles now with on-board connectivity, which are equipped with cellular and internet access, as well as allowing for information to be shared among on-board devices and systems, and with external systems and services. Moreover, low latency communications are required for autonomous driving technologies and advanced driver assistance systems (ADAS).

Reliable sources mentioned that more complex automotive communication systems are required for all the above developments, which would be supported by reliable transmission standards along with data delivery in real-time. The development of Ethernet TSN standard was expressly aimed at meeting these needs, sources further said.

Reportedly, the new product family of Toshiba responds to the demand in market with support for both the new TSN as well as the current AVB networking standards. Simpler implementation is offered by the TC9562XBG than the current product family.

Expanded interface capabilities are supported by TC9562AXBG with RGMII, plus the SGMII, MII and RMII interfaces, of current products. In addition to the capabilities of TC9562AXBG, TC9562BXBG supports Ethernet TSN standards IEEE 802.3br, IEEE 802.1Qbu and IEEE 802.1Qbv.

For the TC9562 series, Toshiba is purportedly targeting a low-power mode, with power consumption of 0.5mW and a recovery time of 100ms. The new bridge ICs would be qualified with AEC-Q100 grade 3.
