Why The ICs Were Developed for Engineers
In-vehicle infotainment systems are increasingly in-demand, and this means engineers must meet the increasingly-stringent automotive standards that IVIs require, particularly when designing and developing such technology. Toshiba developed the TC9594XBG and TC9595XBG interface bridge integrated circuits because the manufacturer wanted to reduce the challenges that engineers encounter when dealing with automotive IVI systems.
Consider that the functionalities of IVI automotive systemsâand therefore their design demandsâprove increasingly challenging the more they lack support for different types of in-vehicle infotainment protocols.

Toshibaâs two bridge interface ICs (pictured above) are designed to support electrical engineers (and of course other design experts) who need to meet various compatibility requirements when developing and designing their IVI systems. As covered next, this is achieved thanks to the productsâ support for multiple display types, which helps the interface bridge ICs to âbridgeâ the gap between an IVIâs display and interface.
The Design Specifications and Benefits of Toshibaâs ICs
Toshibaâs TC9594XBG and TC9595XBG are both part of a 7-by-7 mm VFBGAâvery thin profile fine-pitch ball grid arrayâ80 package. Both ICsâ internal registers are accessed through either the SPI (serial peripheral interface) or the I2C bus.
At 166 megahertz (24 bit), the TC9594XBG supports parallel input and a four-lane, one channel output to Xilinxâs MIPI (Mobile Industry Processor Interface) DSI-TX.
The two inputs supported by the TC9595XBG, moreover, are four-lane one-channel MIPi DSI (Display Serial Interface) or MIPI DPI (Display Pixel Interface). As for its output, the TC9595XBG supports the Vesa DisplayPort 1.1a standard.
Fundamentally, as Toshibaâs product video explains, the two ICs have the âcapability to connect multiple display interface types to host processors [and] bridge the display-interface gap to build your solutionâ. More information on the manufacturerâs display interface support is available on Toshiba.comâs Semiconductor section, as well as its automotive IC specifications table below.

The Core Advantage of Toshibaâs ICs
Toshibaâs bridge integrated circuits, the TC9594XBG and the TC9595XBG, offer support to engineers by reducing the complexities that are prevalent when working with IVI systems. As touched on earlier, perhaps the biggest advantage of these interface bridge ICs is that both products support different types of display interfaces. The technology altogether offers enhanced functionality to in-vehicle infotainment systemsâand ultimately can reduce the engineering demands of IVI design and development.
