Because of the Si4438 transceiver’s high performance and integration, there is no need to add external PAs, low-noise amplifiers (LNAs) or surface acoustic wave (SAW) filters for most wireless applications, thereby reducing BOM cost. The on-chip PA can be used to compensate for the reduced performance of low-cost antennas while competing solutions require larger, costlier external PAs to achieve comparable performance. An integrated temperature sensor, power-on-reset and GPIOs further reduce system cost and board size. The Si4438 IC is designed to work with a low-cost MCU, a crystal and a few passive components to create a cost-effective wireless system. Its 4 mm x 4 mm package is also the smallest in its class, minimizing board real estate.The Si4438 IC is pin compatible with Silicon Labs’ Si446x EZRadioPRO transceivers, which can be used in worldwide sub-GHz ISM frequency bands for smart meter/smart grid products designed for global deployment. The EZRadioPRO family includes a complete line of transmitters, receivers and transceivers covering a wide range of wireless applications. In addition, Silicon Labs offers Ember® ZigBee® wireless networking solutions for smart energy and connected home applications in the 2.4 GHz band, as well as 32-bit Precision32 MCUs, mixed-signal 8-bit MCUs, wireless MCUs, and digital isolators for smart metering applications. “Smart metering and other smart grid applications require highly sophisticated and yet cost-effective and easy-to-deploy wireless technology,” said Diwakar Vishakhadatta, vice president and general manager of Silicon Labs’ Embedded Systems business. “China’s fast-growing smart metering market will benefit from wireless connectivity solutions that deliver exceptional performance and ultra-low sleep current at minimal BOM cost. Silicon Labs’ new Si4438 IC is the ideal sub-GHz transceiver to meet these application challenges for China’s smart grid.” Developer-Friendly Wireless Development Environment Silicon Labs provides an array of hardware and software development tools to help developers get their smart metering products to market faster. The 4438-490-PDK development kit provides all the essential tools to evaluate the Si4438 IC for smart metering designs operating at the 490 MHz frequency. The kit includes two C8051F930 MCU-based motherboards, two RF pico-boards and two antennas optimized for the 425-525 MHz frequency band, making it very easy to set up a wireless link. Silicon Labs’ GUI-based Wireless Development Suite (WDS) software with sample code enables developers to quickly and intuitively create and deploy robust, cost-effective wireless applications with little or no specific RF design and configuration experience.
