Microchip ATSAMR34J18B-I-7JX MCU, LoRa Transceiver, USB, 256KB Flash, 64 TFBGA 6x6x1.20

Technical description of the product (ATSAMR34J18B-I-7JX):

The Microchip ATSAMR34J18B-I-7JX is an ultra-low power microcontroller (MCU) with an integrated UHF transceiver for LoRa communication. It features a 32-bit ARM Cortex-M0+ processor, 256KB Flash memory, and 40KB SRAM (8KB battery-backed) in a compact 6x6 mm BGA package. With sleep currents as low as 790nA, it is ideal for battery-powered remote sensor applications. Peripherals include up to 5 SERCOMs (configurable as I2C/SPI/UART/LIN), 8 12-bit ADC channels, 2 analog comparators, and custom logic modules. The transceiver supports LoRa, FSK, MSK, and GSK modulation, offering up to 20 dBm TX power and -148 dBm RX sensitivity. Supported by the SAM R34 Xplained Pro Evaluation Kit, Atmel Studio, and a detailed chip-down design package, this device simplifies development and accelerates time-to-market for LoRa end-nodes.
