Mikhail Dmitriev ARM Cortex - offensive on all fronts
The conservatism of the developers of radio electronic equipment is known to all people involved in the production of electronics. While PC programmers over the past ten to twenty years have changed toolboxes, development environments and operating systems for which they had to develop applications dozens of times, electronics developers continued to use the good old 51s, atmels, etc.

Vitaly Shevchenko Optimized microcontroller for low power applications from Atmel. Based on the materials of the seminar "Day of Atmel"
The need to use components with low power consumption arises when it comes to compact, battery-powered devices. This problem is acute in devices that use AA or AAA batteries. The control system for such devices must be effective enough to ensure not only control of the charge/discharge of the battery at threshold values, but also to effectively control the load (motor or powerful LED). At the same time, the form factor and price of such a device should decrease. The article will talk about the novelty of Atmel, will give brief characteristics and give advantages in comparison with competing solutions in the electronic components market.

Alexander Novitsky Synchronous serial interface SPI in microcontrollers "from A to Z" and its implementation on the example of ADuC70xx from Analog Devices
At first, this article was supposed to describe the implementation features of the synchronous serial SPI interface in the ADuC70xx family of single-chip microcontrollers (hereinafter - MC) from Analog Devices. The author intended not only to look at the specifics of the SPI implementation, but also to discuss when these features are useful, how and for what they should be used.

Alexander Baev Vehicle navigation trackers Novacom
Monitoring and determining the location of moving objects, today, is increasingly popular among the owners of vehicle fleets. This segment of the market is expanding extremely quickly - if earlier the movement of especially valuable objects was monitored, now it is equipped with appropriate devices for cars, trucks and special vehicles. In addition, it has become a reality to supply people and animals with navigation devices in order to know their location at any given time.

Artem Kozlov Aimtec voltage stabilizers with an output current of up to 1 A work without heatsinks!
Using switching stabilizers AMSR-78 with an output power of up to 12 W, it is possible to significantly improve the compactness, manufacturability and reliability of electronic devices. This effect is achieved due to the rejection of radiators, which are necessary for analog stabilizers when operating with a load of 2-3 W.

Valery Zotov Practical course of end-to-end design of digital devices based on FPGAs from Xilinx. Part 25
The twenty-fifth part of the course discusses how to program parallel and serial flash memory chips from various manufacturers and supported by the iMPACT CAD module of the Xilinx ISE series. The process of direct loading of configuration data into serial EPROM and reverse reading of information through the SPI interface, as well as programming through the JTAG port of the FPGA FPGA, is described. Provides the necessary information for performing BPI parallel configuration flash programming operations.

Maxim Alekseev Devices for converting signals of serial interfaces USB-UART
The paper deals with the conversion of signal formats used in serial data transmission channels. In view of the popularity of the USB interface and the existence of many devices with serial interfaces of the RS-232/RS-485 type, the task of direct and inverse conversion of serial data of these types of interfaces is urgent. The article discusses the features of using specialized devices manufactured by Silicon Laboratories for these tasks.
