Silicon Labs announced that it has expanded its family of 8-bit Si10xx wireless microcontrollers (MCUs) with two new options optimized for both cost-sensitive and performance-intensive designs. By combining its ultra-low-power MCU technology with its sub-GHz EZRadio® and EZRadioPRO® transceivers in a single-chip solution, Silicon Labs has created new energy-friendly wireless MCUs that achieve industry-leading RF performance with the lowest overall power consumption in their class. Supporting worldwide frequency bands from 142 to 1050 MHz with low-power sleep and active modes for extended battery life, the Si106x and Si108x wireless MCUs address the low energy and RF connectivity requirements of home automation, security and access control, sensor networks, asset tracking and long-range control applications for the Internet of Things. The highest performance and smallest wireless MCU solutions on the market, the Si106x and Si108x devices integrate an energy-efficient 8051 MCU and a sub-GHz RF transceiver into a 5 mm x 6 mm QFN package. This compact footprint makes the Si106x/8x wireless MCUs an ideal fit for space-constrained applications that require wireless connectivity as well as ultra-low power for long battery life.
