Description
General part information
ATSAMR34 Series
The ATSAMR34J18 is an ultra-low power microcontroller combined with a UHF transceiver communication interface. It uses the 32-bit ARM® Cortex®-M0+ processor and offers 256KB of Flash and 40KB of SRAM (8KB battery backed) in a compact 6 x 6 mm BGA package. With ultra-low power sleep currents as low as 790nA, the ATSAMR34J18 devices are ideal for battery powered remote sensor applications.
The highly configurable peripherals include up to 5 SERCOMs (configurable as I2C/SPI /UART/LIN interfaces) with one in the low power domain, 8 12-bit ADC channels, 2 analog comparators and custom configurable logic modules. The transceiver supports LoRa, FSK, MSK and GSK modulation and delivers up to 20 dBm TX power with an RX sensitivity down to -148 dBm.
Supported by certified SAM R34 Xplained Pro Evaluation Kit, Atmel Studio and a detailed chip-down design package, these devices highly simplify the development and accelerate the time to market for LoRa end-nodes.
