Lattice and Mediatek Announce superMHL Smartphone Reference Designs Supporting 4K over USB-C

Two standards are competing to bring 4K video output @ 60 Hz and 8K over USB type C connectors: DisplayPort 1.4 and superMHL. Lattice, who purchased Silicon Image last year, and Mediatek have collaborated to provide reference designs supporting superMHL and based on Helio X20 deca-core processor combined with Lattice components. Lattice SiI8348 MHL transmitter would handle 4K 60 fps video and MHL power, while Sil7033 USB type-C port controller would also handle USB 3.1 data transfer up to 10 Gbps, USB-C power delivery (PD), MHL Alt-mode on USB-C. Lattice also leverage their SiI7013 mobile USB Typer-C port controller, SiI9396 mobile superMHL/MHL to HDMI bridge, and other chips to offer accessories such as USB-C to HDMI adapters, MHL cables, USB-C charger, and USB-C dock with multiple USB ports and HDMI output. Anandtech notes that one the main problem with USB type C connector is likely to be the cable, as many […]

Intel Reference Design Program for Android Promises Devices with Firmware Updates Tracking AOSP for 2 Years

If you’ve ever bought a low cost Chinese smartphone or tablet, you must know you can’t really expect firmware updates, especially with a different Android version. For example, if you’ve purchased an Android 4.1 phone or tablet a couple of years ago, more likely than not, it’s still stuck to the same version. Intel intends to change all that by launching the Intel Reference Design Program for Android. Yes, Intel has provided reference designs in the past, but this program goes further, especially with regards to Android support, and firmware updates. This is the way it all works: Manufacturers can choose a set of pre-qualified components to build their Android device. Intel will provide a single Android image that works with the drivers to support all components. Intel will take care of GMS (Google Mobile Service), and CTS (pre-)certification for their customers. Intel has committed to provide updates within 2 […]

Texas Instruments Releases Zigbee Home Automation Gateway Reference Design Based on BeagleBone Black

Texas Instruments has recently release a complete Linux based Zigbee home automation gateway based on BeagleBone Black development and CC2531 Evaluation Module Kit hardware which you can purchase for about $100 in total, and including Z-STACK Ubuntu gateway installer, as well as Z-STACK Home, a ZigBee Home Automation (ZHA 1.2) compliant protocol stack for the company’s CC2530 and CC2538 SoCs. I won’t go into details about the BeagleBone Black as I have already covered it into details previously. However, the hardware has slightly changed since the initial release, as the 2GB eMMC has now been replaced by a 4GB eMMC, and price has been increased to about $55. CC2531 evaluation module kit is comprised of CC2531 USB Dongle which you can connect to the USB port of a PC, or in this case a BeagleBone Black, for 802.15.4 / ZigBee applications. TI also provides CC2531 USB Firmware Library on their site to let developers […]

Intel Showcases Tablet / 2-in-1 Reference Design based on 14nm “Broadwell” Core M SoC

Intel has unveiled a thin tablet reference design at Computex 2014, in Taiwan, which is based on their upcoming “Broadwell” Core M processor manufactured using 14nm process technology, which will be the most power efficient Intel Core processor to date. Intel fanless mobile PC reference design features a 7.2mm thick, 12.5″ tablet that weights 670 grams. You can also connect it to a media dock providing additional cooling allowing more performance, as well as a keyboard dock. Intel expects 2-in-1 products (tablet + laptop) based on Intel Core M to be available later this year.     Intel claims 60% lower power dissipation, 20 to 40% better performance, and 10 to 45% low SoC power, and half the package footprint compared to third generation “Haswell” Core processors, which will allow fanless and thin designs. Currently Mobile Haswell Core processors have a maximum TDP of 11.5W to 47W, so in theory, at best, Broadwell SoCs might achieve […]
