MediaTek has unleashed what it boasts as the industry's first 2T2R 802.11n WiFi AP/router SoC. The MT7628 enables high data transmission rates for voice and video applications in smart homes while consuming the least amount of power when compared to similar products available in the market, stated the company. For OEMs, the SoC also allows them to manufacture products at the lowest BOM cost, MediaTek added.

Integrating a 2T2R 802.11n WiFi radio and a 580MHz MIPS 24KEc CPU, the MT7628 uses 18 per cent less power than other chipsets in the market and promises exceptional wireless performance and throughput, enabling consumers to effortlessly control their home network, connected appliances and cloud services at home or on the go.

The MT7628 also comes with a range of interfaces, including 5p FE switch, USB, PCIe, SD-XC, I2S/PCM and multiple slow I/Os, enabling consumers to easily connect to an extensive range of Internet of Things (IoT) appliances.

This latest development by MediaTek is another example of the company's dedication to putting high-end, inclusive technology in the hands of everyone, allowing consumers around the world to realise the limitless possibilities of smart homes.

Showcasing the platform's high performance and diversity of application, MT7628 runs two operation modes, router mode and IoT mode. The IoT mode supports SD-XC, eMMC, PWM, SPI slave, the third UART and more GPIOs; and the router mode enables the PCIe interface to connect to 802.11ac chipsets for 2 x 2 802.11ac DBC routers.

The high performance USB 2.0 allows MT7628 to add 3G/LTE support on a router or H.264 image sensor processor to enable the wireless IP cameras. For smart routers, MT7628 supports SD-XC, USB 2.0 and PCIe-to-SATA for home NAS. MT7628 can support WiFi and Bluetooth high quality audio via 192Kb/s, 24bits I2S and enable Wireless VoIP applications through PCM.

Based on MediaTek's mobile WiFi architecture, the MT7628 family includes two part numbers: MT7628K and MT7628A. MT7628K, with embedded DRAM, enables applications to have a small memory footprint, rating power adapter and PCB size, and is geared for powering smaller appliances. MT7628A supports external DRAM for applications with a rich feature set based on MediaTek's Linux SDK and OpenWrt SDK.

MT7628-powered devices will be commercially available in 4Q14.
