LORA® (long distance) technique combines long-distance wireless connectivity and low power performance, enlarges coverage of the Internet of Things (IoT). In order to speed up the development of LORA network solutions, Microchip Technology Inc. (US Micro-core Technology Co., Ltd.) introduces a highly integrated LORA system package (SIP) series, which uses ultra-low power consumption 32-bit microcontroller (MCU), SUB-GHz RF LORA transceiver and software protocol stack. SAM R34 / 35 SIP brings certified reference design and proven interoperability, compatible with the main LoraWanTM gateway and network providers, greatly simplify hardware, software, and supporting the entire development process. The device also provides the lowest dormant power consumption in the industry, extending battery life of the remote icon.
Most LORA terminals maintain sleep mode over a longer period of time, only when transmitting a small packet, occasionally wake up. SAM R34 devices use SAM L21 ARM® Cortex®-M0 + ultra-low power MCU, dormancy mode is low to 790 NA, which significantly reduces the power consumption of the final application and extends battery life. For a variety of long-distance, low-power Internet access applications, high integration, and 6 x 6 mm compact package applications for high integration and use of 6 x 6 mm compact package applications. SAM R34 / 35 series.
In addition to ultra-low power consumption, the simplified development process also allows developers to combine their application code with Microchip's LoraWan protocol stack, speeding design speed, using ATSAMR34 supported by Atmel Studio 7 Software Development Kit (SDK) XPRO Development Board (DM320111) Fast start prototype design. The development board obtains the Federal Communications Commission (FCC), the Canadian Industry (IC) and Radio Equipment Directive (RED) certification, and developers can ensure that their design meets government requirements of various countries.
LORA technology is designed to allow low-power applications to use LoraWan Open Protocol to get a larger communication range than ZigBee®, Wi-Fi®, and Bluetooth®. Lorawan is ideal for smart cities, farm monitoring and supply chain tracking, etc., which makes it possible to create flexible networking networks that are running in urban and rural environments. According to Lora AllianceTM, the number of Lorawan operators over the past 12 months has risen from 40 to 80, and more than 100 countries are actively developing Lorawan networks.
Steve Caldwell, vice president of Microchip Wireless Solution Business Department, said: "The LORA ecosystem is entering the accelerated development phase. As a found member of Lora Alliance, Microchip has always played an important role in the process of success. SAM R34 is very It is a one-stop provider of Microchip still a small low-power device to provide free software, excellent support and reliable supply. "
SAM R34 / 35 Series is supported by Microchip's LoraWan protocol, adopting certified and tested chip-level packages, allowing customers to accelerate the design speed of RF applications, and lower risk. With support for Lorawan's 862 to 1020 MHz range Lorawan, developers can simplify design processes and reduce inventory pressure within the world. SAM R34 / 35 Series supports A-class and C-class terminal devices, as well as exclusive points to point connections.
Supply
Microchip's SAM R34 / 35 LORA series offers six device models, and developers can flexibly select optimal memory and peripheral combinations based on their final application. The series includes a SAM R34 device with a 64-pin TFBGA and a SAM R35 device without a USB interface.
