TI WiLink 7.0 packs WiFi-N, Bluetooth 3.0, FM & GPS onto single chip

While we focused more on Texas Instruments’ eye-catching OMAP4 development device when we visited the company a few weeks ago, we also had a chance to talk to their wireless chipset team.  TI’s combo chipsets – which pack various mixtures of WiFi, Bluetooth, FM and GPS onto a single component – get a new sibling today, in the shape of the WiLink 7.0, an integrated chip that combines all four of those wireless technologies.

The TI WiLink 7.0 squeezes WiFi a/b/g/n, FM transmit/receive, Bluetooth 3.0 and GPS onto a chip that’s 50-percent smaller than current alternatives and – perhaps more importantly – uses 30-percent less power.  That adds up to smaller, longer lasting mobile devices, and devices that have better use of their wireless connectivity.  As TI explained to us, when you’re using separate components there’s a limit to the amount of interconnectivity between them; if you combine them into one chip, meanwhile, things like power-management and intelligent usage profiles become possible.

We’ll have to wait a while to see the first commercial products using the Texas Instruments WiLink 7.0, however; while the chip is sampling now to OEMs, products aren’t expected until the end of the year.


Press Release:

Texas Instruments delivers industry’s first quad-radio single chip

TI raises the bar with WiLink™ 7.0 solution, integrating WLAN, GPS, Bluetooth® and FM transmit/receive technologies on a true single-chip

DALLAS (February 9, 2010) – Demonstrating its leadership in the wireless connectivity market, Texas Instruments Incorporated (TI) (NYSE: TXN) today unveiled its WiLink™ 7.0 single-chip solution, the industry’s first offering to integrate WLAN 802.11n, GPS, FM transmit/receive and Bluetooth® technologies. Integrating these capabilities on a true single chip, the 65-nanomenter WiLink 7.0 solution reduces costs by 30 percent, reduces size by 50 percent and delivers superior coexistence performance as compared to today’s existing solutions. Built on seven generations of proven technologies and legacy software, this single-chip solution further extends TI’s heritage of bringing technologies previously seen in high-end devices to the broad mobile market. The WiLink 7.0 solution will be showcased during Mobile World Congress 2010 in the TI booth (8A84, Hall 8). For more information, visit www.ti.com/wilink7pr.

“TI’s announcement that its Bluetooth/FM/GPS/WLAN combination IC is sampling to major OEMs marks the first of its kind, demonstrating the strong future for combination ICs that enable device manufacturers to offer multiple radios without sacrificing performance, space requirements or profit margins,” said Lisa Arrowsmith, analyst, IMS Research. “IMS Research forecasts that by 2013, more than 4.5 billion combination ICs featuring a variety of radios will have been shipped.”
