Toshiba TC358778XBG Parallel Port to MIPI DSI

Toshiba TC358778XBG Parallel Port to MIPI Display Serial Interface (DSI) is a bridge device that converts RGB to DSI. All internal registers can be accessed through I2C or SPI. The Toshiba TC358778XBG Parallel Port to MIPI DSI defines a high-speed serial interface between a peripheral, such as an active-matrix display module, and a host processor in a mobile device. This feature allows an engineer to provide higher performance, lower power, less electromagnetic interference, and fewer pins than current devices while maintaining compatibility across products from multiple suppliers.
