Silicon Labs introduced the complete Wireless M-Bus platform solution designed to simplify the development of wirelessly connected smart meters for electricity, gas, water and heat resources in the European market. Silicon Labs’ comprehensive smart metering solution includes the Wireless M-Bus software stack and wireless starter kits to speed time to market. The Wireless M-Bus solution is portable across Silicon Labs’ wide array of energy-friendly ARM®-based microcontrollers (MCUs) and sub-GHz wireless ICs, and it supports all modes for smart metering in Europe including the popular 169 MHz N modes. The open Wireless M-Bus protocol provides a proven, easy-to-deploy wireless connectivity solution for smart metering and smart grid applications. Based on the EN13757-4/3 European standards, Wireless M-Bus specifies seamless sub-GHz RF communication between smart utility meters, data concentrators, mobile readout devices and heat cost allocators. Wireless smart meter applications require long life for battery-powered meters such as water, gas and heat meters. To address this need, the Wireless M-Bus protocol requires very little overhead for the small amounts of data used by meters, enabling battery life of up to 15-20 years. Proven over the past several years in numerous field tests and deployments in many countries, Wireless M-Bus has become a widely accepted standard for smart metering in Europe. Silicon Labs’ Wireless M-Bus platform solution covers all region-specific requirements throughout Europe. The software stack complies with the Wireless M-Bus specification (EN13757-4), the Wireless M-Bus Application Layer (EN13757-3) and the Application Layer of the Open Metering System (OMS) Group. The stack supports a wide range of modes at 868 MHz and 169 MHz, from the physical layer to the application layer. Supported modes include T1, T2, S1, S1-M, S2, C1, C2, N1 and N2 (a-g), with ultra-fast preamble detection for the N modes without sacrificing RF performance. The Wireless M-Bus platform solution is optimized for modularity and scalability, high RF performance, ultra-low power and a small memory footprint (as small as 32 KB flash depending on mode and device type). The software stack provides application programming interface (API)-based access for both application and extended data link layers. The stack also includes an optional serial command interface to enable control of the Wireless M-Bus software from an external host processor. Unlike competing solutions, Silicon Labs’ Wireless M-Bus platform uses a hardware AES encryption engine to provide security for metering systems. The Wireless M-Bus solution’s modular architecture features an open hardware abstraction layer (HAL), providing developers with complete flexibility to select the optimal Silicon Labs MCU and sub-GHz RF devices to meet the performance, cost and size requirements of their metering applications.

Silicon Labs Launches Plug-and-Play Isolated Power Supply Solution, Si88xx Isolators
Apr 2 15
Silicon Labs introduced a new family of high-speed, multi-channel digital isolators designed to provide a complete, highly integrated solution for signal and power isolation. Silicon Labs’ new Si88xx isolators feature an integrated dc-dc converter with 78% efficiency, deliver up to 2 W of power, and offer very low electromagnetic interference (EMI) emissions and high noise immunity. The Si88xx family reduces system cost, speeds time-to-market and enhances reliability for applications in harsh, noisy operating environments including factory automation, process control, programmable logic controllers (PLCs), solar inverters and automotive battery management. Silicon Labs’ Si88xx isolator family addresses a critical need in industrial automation for plug-and-play isolated power supplies. Developers often must design made-from-scratch isolated power supplies, which can be a time-consuming, frustrating and costly process requiring numerous discrete components. Discrete power isolation solutions commonly use field-effect transistors (FETs), controllers, single-channel isolators or optocouplers, and other components. In contrast, a design based on a multi-channel Si88xx isolator requires the addition of only one miniature ferrite core transformer and a few discrete passive components. Solutions based on Si88xx isolators ultimately save multiple design iterations and reduce bill-of-materials (BOM) cost and design complexity while enhancing noise immunity and power efficiency. Si88xx digital isolators provide up to 2 W of isolated power by harvesting power from the primary side to supply secondary side power. The isolators offer up to four high-speed digital isolation channels with excellent timing characteristics including low propagation delay and low jitter, enabling longer system lifetimes at high voltages. These signal isolation characteristics are critical for developers designing systems for industrial automation, battery management and motor control requiring long-term performance. The low-power, high-speed Si88xx digital isolation channels offer substantial data rate, propagation delay and reliability advantages over legacy isolation technologies including optocouplers. The Si88xx family supports data rates of up to 100 Mbps, and Si8xx devices achieve typical propagation delays of 23 ns. The Si88xx isolators incorporate Silicon Labs’ proven, patented digital isolator technology with an on-chip isolated dc-dc converter providing regulated output voltages of 3.3 V or 5.0 V (or >5 V with external components) at peak output power levels of up to 2 W. The robust dc-dc converter architecture, coupled with a ferrite core isolated transformer, provides ample power to self-power the secondary side of the isolator as well as other components such as RS-485 or CAN transceivers, microcontrollers and analog-to-digital converters (ADCs). The dc-dc converter is based on a modified fly-back architecture with secondary side sensing and feedback to the controller with external compensation. The power switches use zero voltage switching (ZVS) techniques to minimize power losses as well as dithering to minimize EMI. The Si88xx isolators incorporate multiple safety features including a built-in soft-start function providing protection from inrush currents, a cycle-by-cycle current limiting capability and thermal detection/shutdown. The integrated dc-dc converter includes a built-in secondary sensing and feedback signal, eliminating the need for an additional opto feedback path while enabling excellent line and load regulation for greater system stability. The dc-dc converter also features a shut-down option and user-adjustable switching frequency for fine-tuning the EMI profile to suit each developer’s application needs. Samples and production quantities of Si88xx digital isolators are available now in 20-pin WB SOIC packages. Ordering options include a choice of dc-dc converter features, isolation channel configurations and a fail-safe mode. All Si88xx products are certified by UL, CSA, VDE and CQC. Si88xx family pricing in 10,000-unit quantities begins at $2.42. To help developers evaluate the performance of Si88xx isolators, Silicon Labs’ Si88xxxISO-KIT evaluation kit is available now for $29.
