CC3235S is TI's first IoT WiFi-chip to support the 5GHz band

27.06.2019

The new dual-band 2,4/5 GHz wireless Wi-Fi microcontroller from Texas Instruments belongs to the SimpleLink family and is available in two versions:

1. The CC3235S includes 256KB of RAM, IoT network security, and MCU-level security features such as file system encryption and developer intellectual property protection (MCU image encryption).

2. The CC3235SF builds on the CC3235S and includes an additional 1MB of executable Flash memory for user application needs.

The SimpleLink WiFi CC3235x family of devices is a dual-band system-on-a-chip (SoC) solution that combines two processors within a single chip:

1. Application Processor: Arm Cortex-M4 MCU 80 MHz with 256 kB of RAM dedicated to the user and optional 1 MB of executable Flash memory.

2. Network processor to run all logical levels of Wi-Fi and Internet. This ROM-based subsystem completely offloads the host MCU and includes a 802.11GHz and 2,4GHz dual-band 5 a/b/g/n radio, a Baseband processor, and a MAC layer with powerful hardware cryptography.

The new SimpleLink CC3235S/CC3235SF Wi-Fi MCUs simplify IoT design and speed time to market with Wi-Fi CERTIFIED (MCU) certification.

Features of CC3235S:

Support for 802.11a (5 GHz).

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Robot car competition 19.04.2014

Audi, part of the Volkswagen Group, has announced the nominees for the Audi Urban Future Award 2014, dedicated to solving transport problems in metropolitan areas. The winner will be determined in October and will receive a cash prize of 100 euros from the automaker.

This year, four architectural bureaus, consisting of architects, urban planners, designers and other professionals, will take part in the project. Using the example of representative cities (Berlin, Boston, Mexico City and Seoul), they will show the benefits of the introduction of unmanned vehicles, as well as the development of technologies for the interaction of cars with road infrastructure and with each other.

The team from Boston will pay attention to the analysis of narrow passages in the metropolis and will offer progressive solutions for optimizing the transport network. In particular, the researchers will demonstrate the possibility of reducing parking spaces through the use of automatic parking systems.

We are talking about functions that allow the car, on a signal from a mobile device, to independently search for a free parking space, park there, and then return to the owner. Volvo is also working in this direction.

A group of experts from Berlin will focus on technologies for efficient data exchange between private cars and public transport. Contestants representing Seoul will talk about ways to network cars in cities and communicate with motorists for entertainment and other purposes. The authors of this project will demonstrate the benefits of the interaction of drivers with the digital world.

Contestants from Mexico City will show how well Connected Cars can use city traffic information to reduce traffic congestion, reduce harmful emissions and speed up the movement of cars from one point to another.
