NXP launches K32W061/41 wireless MCUs on Apr 30, 2020   The K32W061/41 portfolio is designed to power the next generation of ultra-low-current multiprotocol wireless devices, supporting Zigbee 3.0/Thread/IEEE 802.15.4 and Bluetooth Low Energy 5.0. It includes several low-power modes and ultra-low TX and RX power consumption, which enables devices powered by K32W061/41 to have extended battery life. With high RX sensitivity and configurable TX output power, K32W061/41 offers reliable and r ...
Semiconductor industry is always evolving at an unprecedented speed. You may feel this trend when changing your smart phone from an older generation to the latest offering from Apple or Samsung, and found that the screen and performance of the device is better than you ever could imagine, just like the time when you change your personla computer several years ago.   However, not only the power of a high-end processor is enhancing continuously, the benefit of technology upgrade also lies in ...

Follow along with me on this path to learn the technology....     Let's dive further into the example Android App "coinfinity". This is the 2nd real thing: Submit a Smart Contract transaction   What is a Smart Contract?  A smart contact is a chunk of executable code. It can be executed "in the block chain". It's called a contract because it ...
Digital Logic have a very nice set of Smart Card readers. I have purchased one of those. They work well with the Infineon Securyty 2Go smart cards I received for the Infineon Blockchain Starter Kit road test. Its a well buit reader from a interesting company. But there's a but .   The readers don't support PC/SC, and to program them, you depend on libraries and executables that are available in binary format. Many, but not all, utilities come with source code. They have dependencies on ...
Audio speakers and headphones are becoming wireless, with Bluetooth and Wi-Fi as the most popular technologies. NFC is the fast and simple way to associate wireless devices, without creating conflicts. No menus, no waiting. The most advanced solution for NFC pairing is connecting two Bluetooth enabled audio devices with just a tap, which creates a multi speaker audio system, or even a ‘silent disco’ if you use two headphones. In the webinar (link below), you will learn how you can ...

Of course we know that 32-bit microcontrollers are getting more and more attention and start to 'dominate' the market since years ago because of the advanced technology node and good power consumption performance. Thus, not all applications needs 32-bit, like co-processors and control unit for a specific module. Sometimes they prefer 8-bit for cost reasons, sometimes for simplicity that they offers to save develop resources. Anyway, 8-bit is still playing the game in the market, just not in the ...

CATM and/or NB-IoT

Posted by papili Mar 10, 2020
The two low volume cellular technologies for IoT are CATM and NB-IoT. Both technologies are used for transmitting limited amounts of data over the cellular network. Both of these technologies ride on the cellular operators LTE network so coverage when fully deployed will be similar to the coverage you get on your cell phone. Both of these technologies have been predicted to explode in terms of the number of devices being placed on the network. Unfortunately, the uptake has been a lot slower than ...
