Controller Renesas R9A02G011

15.04.2016

Renesas Electronics announced the release of the USB Power Delivery (PD) controller, designated R9A02G011. This controller, which replaced the uPD720250 model, complies with the USB PD 3.0 specification. According to the manufacturer, R9A02G011 can be used not only in smartphones and PCs, but also in other cases where DC power is needed, such as computer peripherals, robots, power adapters, projectors and other consumer electronics devices.

Recall that the USB Power Delivery 3.0 specification provides for the ability to supply power up to 100 W via USB by increasing the voltage to 20 V and the current to 5 A. For comparison, the capabilities of the original USB version were limited to a power of 7,5 W (5 V, 1,5 .3.0 A). This allowed us to significantly expand the scope of USB in terms of powering devices and charging batteries. By using an off-the-shelf controller that complies with the USB PD XNUMX specification, developers can reduce device design costs and speed it up.

The R9A02G011's flash memory, oscillator, power-on initialization circuits, and other blocks reduce the number of external components and reduce the size of the printed circuit board. The R9A02G011 chip is available in a 32-pin QFN package. In addition to the controller itself, the manufacturer plans to offer reference samples of solutions based on it.

Evaluation samples of R9A02G011 are now available. Serial production should begin in May. The planned output is 1 million pieces per month.

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, ... >>

Stress damages the bones 21.09.2020

Scientists at the Chinese Academy of Sciences have found out how stress affects the loss of minerals from bones.

Nerves - that is, stress, depression - can literally cause a variety of diseases. But what mechanism is at work here? What areas of the brain are involved and what substances do they use to affect the bones?

It turned out that everything starts with a group of neurons in the terminal strip - the so-called part of the brain in the amygdaloid region, which includes the amygdala, or amygdala, and a number of other nerve centers. Neurons of the terminal strip synthesize the hormone somatostatin, which can also play the role of a neurotransmitter.

Somatostatin reduces the synthesis of somatotropin, another hormone that stimulates bone growth and performs a number of other functions. Under chronic stress, somatostatin neurons of the terminal strip suppress the activity of other neurons that are located in the hypothalamus. All together - the activation of neurons in the terminal stria and the suppression of neurons in the hypothalamus - gave anxious behavior and bone problems.

"Alarming" signals from the hypothalamus come to the nucleus of a solitary pathway - this is the name of the nerve center in the medulla oblongata, which controls the work of many internal organs. The nucleus of the solitary pathway sends signals to the sympathetic nervous system, and the nerves of the sympathetic nervous system process the bones with norepinephrine. And norepinephrine already suppresses the work of bone cells responsible for the growth of bone tissue.
