Single Chip MT7628 Wi-Fi System 2T2R 802.11n

19.09.2014

MediaTek has unveiled the MT7628 single-chip system, which is the first SoC for 2T2R 802.11n Wi-Fi access points and routers, according to the manufacturer. The advantages of the new SoC include a high degree of integration and low power consumption.

By combining a 2T2R 802.11n Wi-Fi RF module with a MIPS 24KEc processor running at 580 MHz, power consumption is 18% lower than other similar solutions on the market.

The MediaTek MT7628 is equipped with a five-port Fast Ethernet switch and a large number of interfaces, including USB, PCIe, SD-XC, I2S/PCM and numerous low-speed interfaces, allowing you to easily connect to a wide range of Internet of Things (IoT) devices.

MT7628 can operate in one of two modes: Router or IoT. In the second mode, SD-XC, eMMC, PWM, SPI slave interfaces, a third UART transceiver and more GPIO lines are available; in router mode, the PCIe interface is enabled, which is used to connect 802.11ac chipsets. The presence of USB 2.0 makes it possible to connect a 3G / LTE modem or an IP camera that transmits video in H.264 format. The ability to organize a PCIe-to-SATA bridge is useful when using the MT7628 in a NAS.

The MT7628 family includes two models: MT7628K and MT7628A. A feature of the first is the presence of built-in DRAM memory, and the second is designed for external memory.

The appearance on the market of devices based on MT7628 is expected in the next quarter.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

RS485 transceivers do not require terminating resistors 22.06.2006

Linear Technology introduced two new ICs: LTC2859 and LTC2861, which are half-duplex and full-duplex RS485 transceivers, their distinctive feature is the presence of a built-in plug-in terminating resistor.

Traditionally, when creating networks based on the RS485 protocol, the user had to independently install 120 ohm terminating resistors. Their installation locations were determined depending on the topology of the connecting lines and the location of the network nodes. As the network expanded, the user had to install additional terminating resistors.

The control program has the ability to connect terminating resistors in the LTS2859/LTS2861 transceivers, while ensuring matching for the required number of network nodes - without any physical participation from the user.
