Microchip Technology Inc., a provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced from the Sensors Expo its first Bluetooth® 4.1 Low Energy module. The RN4020 builds on the Company’s deep Bluetooth Classic experience and carries both worldwide regulatory certifications and is Bluetooth Special Interest Group (SIG) certified. The integrated Bluetooth Low Energy (BTLE) stack and onboard support for the common SIG low-energy profiles speeds time to market while ensuring Bluetooth compatibility, eliminating expensive certification costs and reducing development risks. The module is also pre-loaded with the Microchip Low-energy Data Profile (MLDP), which enables designers to easily stream any type of data across the BTLE link.
Because the RN4020 is a stack-on-board module, it can connect to any microcontroller with a UART interface, including hundreds of PIC® MCUs, or it can operate standalone without an MCU for basic data collection and communication, such as a beacon or sensor. This standalone operation is facilitated by Microchip’s unique no-compile scripting, which allows module configuration via a simple ASCII command interface—no tools or compiling are required.
The designers of cost-sensitive embedded applications are looking for turnkey solutions that make it easy to add the low power consumption and simplicity of Bluetooth LE connectivity, which enables several years of operation from a single battery and has a large installed base of compliant smartphones, tablets and computers. Example markets that need these low-power wireless command-and-control solutions include home automation and appliances; medical and wearable devices; toys, tags, fobs and remote controls; pulse and proximity sensor-based systems; and even industrial applications.
Microchip’s RN4020 Bluetooth LE Smart module includes all of the hardware, software and certifications that designers need to easily add this low-energy connectivity to any design, while easing End Product Listing (EPL) via QDID Bluetooth compatibility testing. All of the programmable profiles are stored and selectable on the module, including Microchip’s flexible MLDP and the common Bluetooth SIG low-energy profiles. In addition to common public profiles, private services can be created via the ASCII command interface. The RN4020 also provides a built-in PCB antenna with 7 dBm transmit power and a receive sensitivity of -92.5 dBm, enabling operation over 100 meters* in a compact form factor of only 11.5 x 19.5 x 2.5 millimeters.
“This industry-certified and compact BTLE module gives designers a convenient way to add the latest Bluetooth 4.1 wireless connectivity to their designs,” said Steve Caldwell, vice president of Microchip’s Wireless Products Division. “The RN4020 combines our comprehensive experience in user-optimized, low-NRE Bluetooth Classic modules with Microchip’s industry-leading manufacturing capabilities and support infrastructure.”
Microchip also announced today the flexible RN4020 Bluetooth Low Energy PICtail™/PICtail Plus daughter board (part # RN-4020-PICtail), which is available now for $49. This board enables code development via USB interface to a PC, and over the onboard In-Circuit Serial Programming™ interface for Microchip’s PICkit™ or MPLAB® REAL ICE™ tools. It also leverages customer investments in Microchip’s existing development boards with a PICtail interface, such as the Explorer 16, PIC18 Explorer and PIC32 I/O Expansion Board. Additionally, the onboard eXtreme Low Power (XLP) PIC18 microcontroller allows the PICtail board to run in standalone mode, powered by USB from the host, enabling portable demonstrations and proofs of concept.
