October 31, 2011 - MediaTek Inc., a leading fabless semiconductor company for wireless communications and digital multimedia solutions, today announced its most advanced Wi-Fi chip designed to enable internet access and peer-to-peer multimedia sharing with smallest footprint and longest battery life for mobile and portable devices. The MediaTek MT5931 integrates 802.11n Wi-Fi MAC, baseband, radio, embedded CPU, and power management unit on a single chip with extremely compact size and power efficiencies, making it best solution to meet the growing high-speed connectivity demand among a wide range of mobile or portable devices.

The MediaTek MT5931 single chip SoC, measuring less than 9mm^2 in chip scale package, further integrates PA, LNA, and T/R switch on chip, making it ideal for applications seeking compact design with only few external components. Advanced Wi-Fi features like STBC, Wi-Fi Direct, and hot spot mode are fully supported for meeting the dynamic changes in Wi-Fi infrastructures to provide superior user experience.

SR Tsai, General Manager of the Wireless Connectivity Business Unit at MediaTek said, "MediaTek is one of the leading companies to offer highly integrated Wi-Fi SoC solution for a wide range of portable and mobile devices. The MT5931 was designed to meet industry’s tier 1 requirements, such as low energy consumption for long battery life, a very compact footprint for highest level of flexibility in PCB designs, and low system manufacturing cost to make Wi-Fi an affordable feature for various segments of consumer electronics devices. With the introduction of the MT5931, legacy consumer devices can be easily migrated to Wi-Fi enabled smart devices with the minimum design and manufacturing efforts."

The MT5931 has entered mass production and shipping to lead customers in large quantities now.
