ROHM SEMICONDUCTOR 2022 13 It is often believed that incorporating Wi-Fi or cellular networks into IIoT applications is more energy demanding compared to Bluetooth-based networks. With recent developments in wireless communication modules, engineers can now incorporate low-power consuming wireless technologies into IIoT systems. These modules offer high radio frequencies with low current consumption, allowing engineers to integrate power-optimized devices into IIoT applications. ROHM's low power solutions for IIoT systems include KX13x accelerometers, BP35C wireless module, BD70522 DC/DC converter, 16-and 32-bit MCUs, and low-current chip LEDs. ROHM is a member of the Wi-SUN Alliance, a global certification association providing communication solutions for large outdoor networks. Wi-SUN Alliance enables a diverse ecosystem of solution providers, including product and silicon vendors, cities, utilities, government institutions, and academia, building smart solutions. It offers a robust certification program, ensuring interoperability in wireless devices for outdoor Field Area Networks (FAN), Home Area Networks (HAN), and other IoT networks. Some key applications include the following: • Smart utilities: Advanced Metering Infrastructure (AMI), peak load management, distribution automation, and smart metering. • Smart cities: Street lighting, infrastructure management, smart parking, environmental sensing, traffic, and transport systems. • Smart home: Smart thermostats, air conditioning, heating, energy usage displays, and health and well-being applications. • M2M: Agriculture, structural health monitoring (e.g. bridges, buildings, etc.), monitoring, and asset management. ROHM's KX132-1211 and KX134-1211 accelerometers offer a high sensitivity range of ±2g to ±64g to meet several sensing needs in IIoT applications. These solutions feature power-saving capabilities such as wake-up and back-to-sleep detection, significantly minimizing power consumption during idle periods. Similarly, ROHM's compact wireless communication module can network up to 1000 units, offering extensive area coverage by incorporating it into social infrastructures such as traffic and streetlights. The BP35C is a WiSun FAN module for secure communications between IIoT devices within a network. Offering in-built security features, it enables high-efficiency power utilization at an ultra-high radio frequency band of 920MHz. ROHM's BD70522GUL is ideal for battery-powered IIoT systems and offers input voltages from 2.5V to 5.5V. The buck converter offers Constant ON-Time (COT) control, ultra-low power mode, exceptional transient response, and extends battery life with its light load efficiency. It also features a programmable output voltage range of 1.2V to 3.3V using VSEL pins, as well as a small-footprint VCSP50L1C package that minimizes inductance and heat dissipation. Moreover, the ML620Q500 16bit and ML630Q400 32-bit MCUs are low-power high- performance solutions that achieve high efficiency in IIoT applications with advanced capabilities. These products are well-suited to battery-driven applications due to their support for low-voltage low- power applications. ROHM also offers a chip LED lineup comprising high power type, rear mount type, side-emitting type, and compact type.
