DALLAS, May 1, 2013 /PRNewswire/ -- Texas Instruments Incorporated (TI)
(NASDAQ: TXN) today 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. For more information on the TCA8424,
visit www.ti.com/tca8424-pr. For more information on the SN65DSI85, visit
www.ti.com/sn65dsi85-pr.

Key features and benefits of the TCA8424

  oExtended keyboard support: Up to 128 (8 by 16) key scan supports standard
    keyboard plus additional custom keys, such as volume control, brightness
    control and forward/back/stop/reload/home. Competing keyboard controllers
    support only 80 keys.
  oUnique simultaneous key press detection: Fixed-length, eight-byte input
    report, only available from TI, can detect up to 14 simultaneous key
    presses, including modifiers, allowing the end equipment to be used in
    applications like gaming.
  oHardware-coded HID and REPORT descriptors: Provides easy software
    integration into the system to ease design and speed time-to-market.

Key features and benefits of the SN65DSI85

  oOptimized MIPI^® DSI interface: Dual 4-lane MIPI® DSI port to dual link
    18/24-bpp FlatLink is compatible with a wide range of graphics processors
    up to WQXGA (2500 by 1600p) resolution at 60 frames per second.
  oSmallest package size: The 5-mm by 5-mm PBGA package is 20-percent smaller
    than competitive devices, saving PCB area in space-constrained mobile
    applications.
  oHigher video bandwidth support: LVDS pixel clock operates up to 154 MHz,
    which is 20-percent higher than the competition. Each DSI lane runs at 1
    Gbps, offering a maximum input bandwidth of 8 Gbps for industry-leading
    data throughput.

Tools and support
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.

A variety of tools and support are also available to speed development with
the SN65DSI85, including IBIS and HSPICE models, DSI tuner software, a
hardware implementation guide and the video configuration guide and
configuration tool software user's manual.

Support is available on the Interface Forum in the TI E2E™ Community, where
engineers can ask questions and get answers from TI experts.

Availability, packaging and pricing
The TCA8424 is available in a 6-mm by 6-mm by 1-mm 40-pin VQFN package.
Suggested retail pricing is US$0.80 in 1,000-unit quantities. The SN65DSI85 is
available in a 5-mm by 5-mm by 1-mm, 64-ball PBGA package. Suggested retail
pricing is US$3.90 in 1,000-unit quantities.
