Si101x devices remain in production, but are not recommended for new designs. For new designs, please use the Si106x/8x Wireless MCUs instead.
The Si101x 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 for longer battery life, higher product performance and lower system cost.
The Si101x wireless MCU family offers devices that are configured with either 16 or 8 kB of on-board flash memory and a maximum transmit output power of +13 or +20 dBm. The Si1014 and Si1015 also include an integrated dc-dc boost converter with a switching efficiency of up to 90%, which can greatly increase system battery life.
