This enhanced connectivity transforms these devices into IoT edge nodes, albeit with the trade-off of increased processing demands and larger memory subsystems.<\/span><\/p>\n<p style=\"text-align: start;\"><strong>IoT Edge Sensor System Challenges<\/strong><\/p>\n<p style=\"text-align: start;\">Many embedded systems are &#8220;connected&#8221; to their immediate environment, featuring capabilities for environmental sensing, mechanical actuation, or human interaction. For instance, smart thermostats are linked to local networks of temperature and humidity sensors and include buttons or capacitive sensors for user input. Similarly, connected cooking appliances aim to interpret user preferences for food temperature and apply heat accordingly.<\/p>\n<p style=\"text-align: start;\">These predominantly &#8220;analog&#8221; systems are integrating into the fast-paced world of cloud communication, posing a unique challenge: should systems be optimized for the slow-moving input of the analog world, or should analog fidelity be compromised for speed and enhanced functionality?<\/p>\n<p style=\"text-align: start;\">To delve into this issue, we&#8217;ll examine a common and straightforward application example\u2014the IoT edge sensor node.<\/p>\n<p style=\"text-align: start;\"><strong>Sleepy, Low-Power Analog Subsystems<\/strong><\/p>\n<p style=\"text-align: start;\">IoT edge sensor nodes require an analog subsystem to measure and monitor environmental conditions such as temperature, humidity, or motion. This analog subsystem includes a microcontroller (MCU) that reads sensor data, processes it, and communicates it over a network.<\/p>\n<p style=\"text-align: start;\">Environmental data typically changes slowly, so most edge nodes do not need to process a continuous, uninterrupted stream of data. Given that an edge node often operates on the same small form-factor battery for several years, it spends most of its time in a low-power &#8220;sleep&#8221; mode and only wakes up periodically to detect changes in the environment.<\/p>\n<p style=\"text-align: start;\"><img decoding=\"async\" style=\"width: 100%;\" src=\"https:\/\/file.flywing-tech.com\/res\/article\/20241025141548154842c46772ebed42ec3d338729d92f7b22166ba.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em><strong>Figure 2. <\/strong><\/em><em>Most environmental sensors monitor slowly varying signals like temperature<\/em><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: start;\">During the waking period, the node gathers data and transmits it across a network. Then, it returns to sleep until it needs to take the next measurement.<\/p>\n<p style=\"text-align: start;\">As the number of edge nodes and the volume of collected data increase in our hyper-connected world, power efficiency and low power operation are critical design considerations to extend battery life in analog subsystems.<\/p>\n<p style=\"text-align: start;\"><strong>Segmenting Embedded Systems for Improved Efficiency<\/strong><\/p>\n<p style=\"text-align: start;\">For <a href=\"https:\/\/www.flywing-tech.com\/blog\/atmega16a-au-an-in-depth-analysis-of-a-powerful-8-bit-microcontroller\/\">embedded systems<\/a>, it is optimal to segment the system into different speed domains using a bridge to connect the fast main processor to analog subsystems. Partitioning enables the analog subsystem to specialize in handling slow-changing tasks while fast, compute-intensive processing tasks are managed by a fast main processor, thereby maximizing the functional strengths of each processor type.<\/p>\n<p style=\"text-align: start;\">With the growing trend of more connected devices, I3C? is emerging as the next-generation serial communication interface to support high-speed chip-to-chip communication. As a successor to I2C, it is better suited for future applications with a faster, smarter interface and sophisticated control capabilities.<\/p>\n<p style=\"text-align: start;\">\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 <img decoding=\"async\" style=\"width: 50%;\" src=\"https:\/\/file.flywing-tech.com\/res\/article\/2024102514173917392d4cca758e58adea7b1e14645420dc2e6b0f7.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em><strong>Figure 3. <\/strong><\/em><em>An example I3C connection between a controller and two target sensor nodes<\/em><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: start;\">I3C maintains backward compatibility with I2C devices, which is crucial for seamlessly integrating I3C into existing hardware platforms. Additionally, I2C devices can coexist with I3C controllers operating at 12.5 MHz, facilitating the migration of existing I2C-bus designs to the I3C specification.<\/p>\n<p style=\"text-align: start;\">For example, a microcontroller that supports both I3C and a legacy communication interface (such as I2C, SPI, or UART) can act as a bridge device. This bridge connects a fast processor to a sensor via the microcontroller. The microcontroller measures the sensor input, calculates results, and efficiently transfers the data.<\/p>\n<p style=\"text-align: start;\">This setup preserves the integrity and speed of the I3C bus while enabling communication between the I3C controller and I2C\/SPI devices through the microcontroller.

With CIPs, engineers can partition each system task for easier function management, reducing component count, code size, development time, and power consumption.<\/span><\/p>\n<p style=\"text-align: start;\"><strong>To Learn More<\/strong><\/p>\n<p style=\"text-align: start;\">In our rapidly changing world, technological innovations and advancements demand faster processing speeds, faster connectivity, and miniaturization. While modern electronics are increasingly connected to our outside world, small-scale and energy-efficient analog subsystems are needed to sense and measure the &#8216;real world&#8217; in connected systems. As environmental data changes usually occur gradually, design goals are in opposing directions.<\/p>\n<p style=\"text-align: start;\">Efficient embedded systems are achieved by partitioning the system into different speed domains, using a bridge to connect the fast processor to the surrounding parts of the system where analog subsystems exist. With I3C becoming the de facto interface for high-speed chip-to-chip communication, it&#8217;s important for engineers to select advanced MCUs that are equipped to fully support the increasing requirements for high performance in the digital realm while maintaining high analog precision for next-generation designs.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The evolution from single-processor embedded systems to multi-processor architectures in IoT edge sensor nodes is revolutionizing real-time data processing.
