New microcontroller from Maxim

21.07.2007

The MAXQ3100 microcontroller from Maxim Integrated Products is a low-power, 16-bit RISC microcontroller. It contains a 160-segment LCD controller, two analog comparators with a 1,25 V precision reference, a separate battery-powered real-time clock module, three 16-bit timers, a digital temperature sensor, and two universal synchronous/asynchronous transceivers, one of which can be used for infrared communication.

This feature set makes the MAXQ3100 microcontroller ideal for use in single-phase electricity meters and other utility meters (water, heat, gas). The microcontroller can also be used in smart sensors, industrial automation devices, household appliances, security systems, thermostats, heating, ventilation and air conditioning systems and other applications.

The microcontroller operates at a fixed frequency of 4,194 MHz, which is synthesized from the original clock frequency of 32,768 MHz. The microcontroller memory block is represented by EEPROM with a capacity of 8 kB and a RAM with a capacity of 512 Bytes. The microcontroller core and I/O are powered by a single 3,3 V supply. For uninterrupted power supply of the real time clock, an output is provided for connecting an additional backup battery.

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, ... >>
