描述 Description

Each ATSAMR30 device is an ultra low-power microcontroller equipped with an IEEE? 802.15.4 compliant radio for the sub-1GHz frequency bands 780 MHz (China), 868 MHz (Europe) and 915 MHz (North America). It uses the 32-bit ARM? Cortex?-M0+ processor and offers 256KB of Flash and 40KB of SRAM (8KB battery backed) in as small as a 5mm QFN32 package. Advanced power management technologies, such as power domain gating, SleepWalking, and ultra low-power peripherals allow for very low power performance and long battery life sensor applications. The ATSAMR30 typically draws less than 500nA at 1.8v battery supply with wake on GPIO, Serial Communication or Real Time Counter.??The highly configurable peripherals includes up to 5 I2C/SPI /UART interfaces with one in the low power domain, 8 12-bit ADC channels, 48 capacitive touch channels with proximity sensing. The sub-GHz Radio supports BPSK and O-QPSK modulation and delivers up to 8dBm TX power with an RX sensitivity of -110dBm.?MiWi, Microchip's proprietary networking technology enables Mesh, Star and Point-to-Point connectivity for the SAMR30 devices.?The MiWi library is available in the Advanced Software Framework (ASF) for Atmel Studio IDE.
