Automotive Interface Bridge ICs

As in-vehicle infotainment (IVI) systems, along with other automotive systems, become more sophisticated, requiring greater functionality and higher performance, an interface gap problem between peripheral devices and Systems-on-chip (SoCs) easily arises. Toshiba interface bridge ICs can help to solve this problem.

Automotive Peripheral Bridge IC

SoCs, widely applied in smartphones and tablets, are increasinly appearing in automotive applications as IVI systems become more sophisticated, requiring greater functionality and higher performance. But because connectivity standards differ among devices such as displays, existing SoCs often lack the interfaces required for automotive networks.

Automotive Peripheral Bridge ICs

Necessity of AMPD (Interface Bridge IC)

SoC with only MIPI I/Fs as AV I/F may require AMPDs to connect external devices such as displays and cameras.

Necessity of AMPD (Interface Bridge IC)

Toshiba’s new range of video interface bridge devices provide HDMI to MIPI® CSI-2 (TC9590), MIPI® CSI-2 to/from parallel (TC9591), and MIPI® DSI to LVDS (TC9592/3) connectivity. The devices are offered in 0.65mm pitch, VFBGA packages between 5 x 5 mm and 7 x 7mm, with the exception of the TC9590 which is housed in an LFBGA64, 0.8mm pitch 7 x 7mm package.

Toshiba has a long track record of developing MIPI®-based interface bridge chips for consumer applications and has drawn on this experience in developing the new automotive IVI range.

Sample shipments of the new devices start in June 2018.

TC9560XBG / TC9560AXBG [Under Development] / TC9560BXBG [Under Development]

Ethernet AVB Bridge solution for automotive applications.

Network interface for In-Vehicle Infotainment system (IVI) , Telematics and other automotive subsystem.

Features
  1. The TC9560 Family supports standards such as IEEE 802.1AS and IEEE 802.1Qav generally referred to as Ethernet-AVB.
    Connected to an application processor or other SoC host, the TC9560XBG allows the host device to deliver audio, video, and data through the 10/100/1000 Ethernet network in an automotive environment.
  2. The connection to the host is via PCIe® running at 2.5/5.0 GT/s (PCIe Gen1.0/2.0), 480 Mbps HSIC or TDM (Time Division Multiplex)/I2S for audio traffic.
  3. Provides an Ethernet PHY interface selectable from RGMII, RMII and MII.
  4. The design target is to achieve a low-power mode that typically consumes 1 mW at room temperature (measured by Toshiba). The TC9560XBG typically takes only 100 ms to return to normal operation (measured by Toshiba) in order to meet the market need. TheTC9560XBG is scheduled to obtain AEC-Q100 Grade 3 qualification.
