TI eases tablet design with interface ICs for connecting displays and keyboards

USA: Texas Instruments Inc. (TI) has introduced two new devices to ease design for tablet designers.

The TCA8424 is the industry's first human interface device (HID) over I2C, 128-key keyboard controller. It eliminates the need to program the device at production, simplifying design and speeding time-to-market. The keyboard controller provides a cost-effective and seamless way to interface keyboards with Windows® 8-based systems.

The SN65DSI85 is a digital serial interface (DSI) to FlatLink interface IC that makes it easier and more cost-effective for designers to connect graphics processors to LCD panels. The SN65DSI85 supports screen resolutions up to 2560 by 1600p in tablets, netbooks, and mobile Internet devices.

The TCA8424EVM showcases the capabilities and benefits of the TCA8424 in keyboard scanner applications. It can be ordered today for US$49. An IBIS model and user's guide are also available.
