Nordic’s nRF52832 SoC powers CWD’s 'CBTMN32' module, enabling users with limited RF design experience to develop complex wireless applications
Nordic Semiconductor today announces that Mumbai-based technology company, CWD Innovations, Nordic’s first official module partner in India, has selected the Nordic Bluetooth® Low Energy (Bluetooth LE) nRF52832 System-on-Chip (SoC) for its ‘CBTMN32’ module.
The CBTMN32 module is a cost-efficient integrated development platform designed for a range of Bluetooth LE applications including connectivity for Internet of Things (IoT) products, beacons, and Bluetooth LE mesh implementations across a range of sectors including lighting, transport and logistics, smart metering, as well as consumer products.
The module is powered by Nordic’s nRF52832 multiprotocol SoC, which features a powerful 64MHz, 32-bit Arm® Cortex® M4F processor, 2.4GHz radio featuring -96-dBm RX sensitivity and offering a total link budget of >100dBm, and generous 512kB Flash memory and 64kB RAM, making the SoC an ideal choice for applications that are complex, processor-intensive, and/or require long range. The module offers the developer the flexibility to choose between an integrated PCB antenna and a u.fl connector for an external antenna.
The CBTMN32 is accompanied by CWD’s proprietary development kit, which enables users with limited RF design experience to configure and evaluate the module. Development is further simplified by Nordic’s unique software architecture, which cleanly separates the RF software protocol stack from the developer’s application code, eliminating the risk of the stack being corrupted when developing, compiling, testing, and verifying application code.
Nordic’s nRF52832 multiprotocol SoC combines the Arm processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF protocol software). The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certifed RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice features Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.
“One of the key reasons that led us to select the nRF52832 SoC was its ability to support Bluetooth mesh,” says Siddhartha Xavier from CWD Innovations. “In addition, we found the chip possesses sufficient Flash and RAM to run complex Bluetooth LE applications, while Nordic’s SoftDevice is a proven solution for consumer products that would be used daily. The availability of Nordic’s technical documentation and reference designs also proved highly valuable.
“Further, our company has strong design and product development capabilities across consumer electronics, wearables, industrial automation, and smart lighting sectors, and the Nordic SoC provides both a high level of reliability and robustness for our customers using our product development skills across these applications.”
