Description

The ATSAMR35J17 is an ultra-low power microcontroller combined with a UHF transceiver communication interface. It uses the 32-bit ARM® Cortex®-M0+ processor and offers 128 KB of Flash and 24 KB 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 ATSAMR35J17 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](https://www.microchip.com/en-us/tools-resources/develop/microchip-studio) and a detailed chip-down design package, these devices highly simplify the development and accelerate the time to market for LoRa end-nodes. **Reference Links:** * To get started with software development, download and install [Atmel Studio 7](https://www.microchip.com/en-us/tools-resources/develop/microchip-studio) * For software examples, update to ASF 3.44 and above in Atmel Studio * To access Chip-down design package, refer to the documents section on this page * [Enable Long Range STAR on SAM R34 ICs and WLR089U0 Module](https://github.com/MicrochipTech/atsamr34_long_range_star) Microchip's complimentary and confidential [Wireless Check online design review service](https://www.microchip.com/en-us/support/design-help/design-check-services) is available for customers who have selected our products for their application design-in\*. \*The online design review service is subject to Microchip's [Program Terms and Conditions](https://www.microchip.com/en-us/support/design-help/design-check-services/design-check-services-program-terms-and-conditions) and requires a myMicrochip account.
