Texas Instruments Introduces New WiFi/Bluetooth Chipsets

[Guest nickcornaglia]

Texas Instruments Introduces New WiFi/Bluetooth Chipsets - TNETW1250 that promise smaller size and better battery consumption offering mobile devices BlueTooth as well as 802.11a/b/g wireless connectivity.

TI's third generation 802.11 chipset is specifically designed for mobile devices such as cell phones smart phones and PDAs. The new solution leverages previous generations of deployed WLAN chipsets as well as TI's experience in cellular, Bluetooth® and Coexistence Packages. The new chipset can be used in 802.11b/g or 802.11a/b/g using TI's WLAN RF solutions. The TNETW1250 offers dramatic improvements in size, power and batter saving that increase active time, as well as cost reductions.

Combined with TI's TNETW3422M radio frequency front end (RFFE) and power amplifier chip, the solution utilizes 25% less board area than competitive solutions.  

The TNETW1250 has been designed to be used with TI's OMAP application processors, GSM, GPRS, CDMA and EDGE UMTS chipset and single-chip Bluetooth solutions.  

Designed specifically for Mobile Phones with TI's ELP™ technology for low power standby modes, the TNETW1250 offers the industry's best standby power consumption and reduced power in active modes. It is designed for real world cell phone applications including VoWLAN, streaming media and fast roaming between access points.  

Key features of the TNETW1250 include:  

- Complete support for 802.11b, g and a.  

- New advancements to TI's Enhanced Low Power (ELPTM) technology:  

- Less than 400 micro-Amperes (uA) in standby mode.  

- Up to 50 percent power reduction in active modes.

- Small size: 25% smaller than competitive WLAN designs.

- Advanced Bluetooth / WLAN coexistence for data and voice.  

- Significantly reduced bill of materials (BOM).  

- Voice over WLAN (VoWLAN) capability including QoS, WPA2 and Cisco® Compatible Extensions support.  

- Optimized system architecture for cellular handsets:  

- Low-pin count interface options.  

- Re-use of standard cell phone clock frequencies.  

- On-chip power management.  

- Major reduction in host processor overhead.
