Si10xx Sub-GHz Wireless MCUs

Si106x/8x wireless microcontrollers (MCUs) combine high-performance wireless connectivity and ultra-low power microcontroller processing into a small 5x6 mm form factor. The devices support major frequency bands in the 142 to 1050 MHz range, including an integrated advanced packet handling engine and the ability to realize a link budget of up to 146 dB. The devices are optimized to minimize energy consumption for battery-backed applications by minimizing TX, RX, active and sleep mode current, as well as supporting fast wake-up times. Si106x MCUs are pin-compatible with Si108x devices that can scale from 8 to 64 kB of flash and provide a robust set of analog and digital peripherals including an ADC, dual comparators, timers and GPIO. All devices are designed to be compliant with the 802.15.4g smart metering standard and support worldwide regulatory standards including FCC, ETSI and ARIB.
