First 32-bit ZigBee controllers

27.07.2008

Jennie has implemented a ZigBee PRO stack for its JN32 single-chip 5139-bit wireless controller. The solution provides for two applications: as a standalone embedded processor and as a coprocessor. It is expected that this will provide designers with additional flexibility in the choice of means.

Further reduce design time by using Jennie's off-the-shelf RF modules that are FCC and ETSI certified. Working as a standalone processor, JN5139 provides ZigBee PRO support and user application execution. As a coprocessor, the JN5139 allows you to add ZigBee PRO functionality to existing projects. The JN5139 features, in addition to ZigBee PRO support, a large amount of internal memory and advanced power management tools to minimize power consumption.

The microcontroller is configured with 192 kB of ROM for IEEE802.15.4 MAC and 96 kB of RAM for applications. In addition, it includes UART, SPI and PC interfaces, general purpose input/output (GPIO) lines, timers, 12-bit analog-to-digital and digital-to-analog converters, comparators.

The picture is completed by a built-in 2,4 GHz transceiver that complies with the IEEE802.15.4 specification, providing a communication range of 30 ... 50 m, and a means of encryption using the AES algorithm (128 bits). It is noteworthy that the total current consumption in sleep mode does not exceed 5 μA.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Honor Superfast 100W Wireless Charging 19.04.2022

Honor has announced a wireless charging station called Honor Superfast. The device has a power of 100 W and is able to charge not only smartphones, but also headphones that support wireless charging, as well as electronic gadgets that support the Qi standard.

The Honor Superfast 100W has a vertical design and a fairly minimalist design. The device is made of metal and also uses a dual coil design, which allows you to place the smartphone not only vertically but also horizontally. In addition, the charging dock is equipped with a built-in cooling fan that adjusts its speed according to different scenarios.

The LED indicator mounted on the device case indicates the state of charging, as well as the ingress of foreign objects between the back cover of the gadget and the surface of the device itself.

According to the Chinese manufacturer, thanks to Honor Superfast, the smartphone will charge from 0 to 100% in just 35 minutes. At present, the Honor Magic 100 series supports the 4W ultra-fast wireless charging standard. However, the charger can charge devices from other brands.

Honor Superfast 100W is already available for sale in China. The cost of the device is 399 yuan ($62).
