Si100x devices remain in production, but are not recommended for new designs. For new designs, please use the Si106x/8x Wireless MCUs instead.
The Si100x wireless Microcontroller (MCU) family offers the industry's lowest power single-chip microcontroller with an integrated sub-GHz RF transceiver. This wireless MCU family is designed to address the specific requirements of low-power embedded systems requiring an RF bidirectional communication link for applications such as smart metering, in-home utility monitoring, wireless security panels, access control and home/building automation.
The Si10xx family has the industry's lowest power consumption in all modes: active, sleep and deep sleep. This ultra low-power consumption is achieved without any compromises in wireless transceiver performance. Having the lowest system power allows longer battery life, higher product performance and lower system cost.
