ATSAMR34J18B-I/7JX Component Type, Microchip ATSAMR34J18B-I/7JX RF Transceiver 137 → 175MHz, 1.8 → 3.6V

The Microchip ATSAMR34J18 ultra-low power microcontroller 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 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.
