MediaTek's new MT7622 SoC is a single platform for 4X4 dual-band and tri-band premium networking devices and introduces several best-in-class features including Bluetooth 5.0 and Hardware NAT, Hardware QoS and a dedicated Wi-Fi engine － MediaTek's Wi-Fi Warp Accelerator. This eliminates bottlenecks by connecting the Gigabit+ class 802.11ac networking with multi-Gigabit internal pathways. It also features the ability to offload the CPU from multiple-users throughput and QoS calculations, all with lower power consumption. The end result is the ability to sustain high-performance for multiple, simultaneous heavy users.
"Based on MediaTek's Adaptive Network technology, the MT7622 features easy setup, network self-healing, roaming, band steering, smart quality of service, and advanced security for whole home Wi-Fi," says Alan Hsu, General Manager of Home Smart Device Business Unit, MediaTek. "For manufacturers looking for flexibility in the design of innovative networking devices, this chipset couples high performance and extensively integrated functionality."
The MT7622, with the power a 1.35GHz rated, 64-bit dual-core ARM Cortex-A53 processor, provides a host of advanced connectivity options like SGMII/RGMII, PCIe, SATA and USB, and 4x4 802.11n FEM integration. To meet the growing demand for applications using audio and voice controls, the MT7622 includes essential audio interfaces such as I2S, TDM and S/PDIF. MT7622 also delivers a rich array of slow I/O in addition to the integrated Wi-Fi, Bluetooth and Zigbee co-existence for home automation gateways.
New Generation Wi-Fi Portfolio
MediaTek also announced its next generation Wi-Fi chipset portfolio. The new MediaTek MT7686, MT7682, and MT5932 devices will deliver high levels of integration with low power consumption for all connected applications, including audio products. The product family consists of highly integrated single chip solutions featuring an application processor, a low-power 1T1R 802.11 b/g/n Wi-Fi subsystem and a Power Management Unit. The application processor subsystem contains ARM Cortex-M4 MCU with floating point unit (FPU). All three were designed with a focus on core principles essential to connected applications, including deep sleep, fast wake-up and reliable data connectivity.
"Our new generation of chipsets have been optimized to deliver a 300 percent improvement in energy efficiency, as well as the ability for a device to re-establish a Wi-Fi connection within 0.1 seconds of waking from sleep mode," says YuChuan Yang, Deputy General Manager of Internet of Things Business Unit, MediaTek.
The MT7682 features a low-power subsystem and fast connection and requires few external components to save porting cost. The MT7686 contains 4MB of embedded RAM and 4MB of embedded Flash memory that makes the chipset an ideal platform for rich data and storage applications. With Wafer Level Chip Scale Package (WL-CSP) technology, the MT5932 has a very compact 3.2 by 3.2mm footprint, saving BOM cost for space-constrained IoT applications.
The three chipsets offer a range of features to meet the needs of uses cases requiring varying levels of embedded memory. All include a number of peripherals, including: SDIO, UART, I2C, SPI, I2S, PWM and auxiliary ADC.
