Si106x/Si108x
ULTRA-LOW POWER MCU WITH INTEGRATED
HIGH-PERFORMANCE SUB-1 GHZ TRANSCEIVER
Description
Silicon Laboratories’ Si106x and Si108x Wireless
MCUs combine high-performance wireless
connectivity and ultra-low power microcontroller
processing into a small 5x6 mm form factor. Support
for all major frequ ency band s in the 14 2 to 1 050 MHz
range is provided including an integrated advanced
packet handling engine and the ability to realize a
link budget of up to 146 dB. The devices have been
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. The Si106x and Si108x Wireless
MCUs are available in a pin-compatible family of
devices that scales from 8 to 64 kB of flash and
provides a robust set of analog and digital
peripherals including an ADC, dual comparators,
timers, and GPIO. These Wireless MCUs are
compliant with IEEE 802.15.4g and support
worldwide regulatory stan dards includin g FCC, ETSI,
and ARIB.
