ATSAMR34J16 Image

The ATSAMR34J16 is a highly integrated LoRa System-in-Package (SiP) with an ultra-low-power 32-bit microcontroller, sub-GHz RF LoRa transceiver and software stack. It uses the 32-bit ARM® Cortex®-M0+ processor and has 64 KB of Flash and 12 KB of SRAM (4 KB battery backed). 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. With ultra-low power sleep currents as low as 790nA, the ATSAMR34J16 devices are ideal for battery powered remote sensor applications.

It is available in a compact 6 x 6 mm BGA package and is ideal for a broad array of long-range, low-power IoT applications that require small form factor designs and multiple years of battery life. 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.
