SAM R30 IEEE 802.15.4 Sub-GHz System-in-Package Datasheet Introduction The SAM R30 is a series of Ultra low-power microcontrollers equipped with an IEEE 802.15.4-2003/2006/2011 compliant RF interface for the sub-1GHz frequency bands such as 780 MHz (China), 868 MHz (Europe) and 915 MHz (North America). It uses the 32-bit ARM Cortex -M0+ processor at max. 48MHz (2.46 CoreMark /MHz) and offers 256KB of Flash and 40KB of SRAM in both 32- and 48-pin packages. Sophisticated power management technologies, such as power domain gating, SleepWalking, Ultra low-power peripherals and more, allow for very low current consumptions. The highly configurable peripherals include a touch controller supporting capacitive interfaces with proximity sensing. The sub-GHz RF interface supports BPSK and O-QPSK modulation schemes according to the IEEE standard and offers output power values of more than +8dBm and receiver sensitivities below -108 dBm.
