What if, in the case of a serially produced device, there is a need to equip it with a USB interface in a short time? How, without delving into the details of the USB protocol, without spending a lot of time studying drivers of various classes and trying to adapt them for their own tasks, to implement such an interface that is simple for the end user? In such cases, the most obvious way out is to use the USB hardware bridges discussed in this article.

Evgeny Rakhno, Alexander Samonin Communication with the outside world using Microchip microcontrollers
As comprehensive as microcontrollers are, virtually any embedded system includes several peripheral modules such as EEPROM, memory, or ADC. Naturally, the microcontroller must be able to communicate with these devices. In this article, we will take a quick look at the most popular data buses, namely I2C, SPI, USB, CAN, and LIN.

Pavel Vovk New Luminary Micro 32-bit Microcontroller Families with USB Host Support
The USB interface has long and firmly entered our life and has become the de facto standard for exchanging large amounts of data not only in household appliances and computer equipment, but also in embedded systems, where previously reliable, but relatively slow and already archaic RS-232 reigned supreme. and SPI. Moreover, the ever-increasing requirements for data transfer speed and interface universality force developers to pay attention to other interfaces.

Mikhail Sokolov, Alexander Grishin, Igor Ocheretyanko A new round of memory evolution: RAM+ROM = MRAM
Today, there are many storage technologies. The most active development is the direction of flash memory - new models with improved characteristics appear regularly. But, this technology directly approached the limit through which the usual flash can no longer step over. Therefore, in recent years, active searches have begun for a solution capable of taking the palm from the flash in the future.

To help the developer
Alexey Grabov Development strategy for the technology of sintered bodies for the components of highly reliable electronic equipment
An important problem of modern domestic electronics is the need to provide new designs of VLSI and MCM (multichip modules) for highly reliable electronic equipment with metal-ceramic cases due to increased requirements for resistance to external factors, heat dissipation and mechanical strength. In this regard, the following questions arise:
• to what extent the technical requirements put forward for the enclosures correspond to the development trends of highly reliable electronic equipment, and is it possible to adjust them;
• is the domestic technology capable of creating products that meet at least the minimum technical requirements;
• what funds are necessary and possible to attract for their implementation?
High-resolution sigma-delta analog-to-digital converters (ADCs) offer significant advantages over other types of multi-bit ADCs. In particular, modern technologies make it possible to manufacture such an ADC in the form of a single-chip integrated microcircuit (IC) with a minimum of external elements and a power consumption of several milliwatts. Texas Instruments is one of the world's leading manufacturers of integrated circuits for sigma-delta ADCs [1], the nomenclature of which includes more than 50 items, combining very high characteristics at a relatively low cost.

Jeff Falin TPS6108x: High-performance switching converters
Highly integrated microcircuits TPS61080 and TPS61081 are switching converters that generate a regulated output voltage of up to 27 V at a low input voltage of up to 2.5 V. These two converters differ only in the maximum allowable current of the built-in switch (0.5 and 1.3 A, respectively). The TPS6108x series converters are designed to operate in a traditional current controlled circuit with constant pulse width modulation (PWM), resulting in low noise. The switching frequency can be set to either 600 kHz for efficient operation with low power loads, or 1.2 MHz if necessary to keep external components as small as possible. With built-in feedback compensation, an internal high-power switch and high PWM frequency, these ICs allow you to build very small (3 × 3 mm) converters in a QFN package for a wide range of applications. For example, they can easily implement a 12 or 24 V fieldbus when powered from a 3.3 or 5 V power supply. Additional benefits include high efficiency, adjustable reference voltage, and multiple protection circuits. This makes the TPS6108x ideal for powering equipment from the 3.6V Li-Ion battery used in most portable devices. The converters also provide the higher voltages required to power TFT LCDs, OLEDs, WLED LED backlights and camera flash lamps.

Industrial control system designers typically need recorders with isolated 0-20mA and 0-10V voltages. Combining a sigma-delta modulator with isolated signal and power inputs from an Analog Devices AD7400 ADC (www.analog.com) and the MSP430 microcontroller from Texas Instruments (www.ti.com) allows you to create reliable analog signal recorders that meet industrial input isolation requirements.
