Nordic Semiconductor nRF52 Series-based Bluetooth low energy module accelerates development of building automation, automotive, and other IoT applications

Delta Electronics’ NQ62X module employs Nordic’s nRF52832 SoC to deliver plug-and-play connectivity solution for high performance, low power applications. An associated development kit simplifies prototyping

Nordic Semiconductor today announces that Taiwan-based Delta Electronics has selected Nordic’s next generation nRF52832 Bluetooth® low energy (previously known as Bluetooth Smart) System-on-Chip (SoC) for its NQ62X Bluetooth low energy module. The module is available with a development platform comprising an ARM mbed-compatible motherboard (DFBM-NQ620), and a daughter board for mounting the module during prototyping.

The NQ62X module is based on Nordic’s nRF52832 SoC and features on onboard antenna. The module has been CE, FCC, and TELEC certified and has passed Bluetooth 4.2 End Product Listing (EPL). Such certification and EPL eases the user’s path to Bluetooth qualification of the end product. The DFBM-NQ610 is a multiprotocol development platform for NFC-A tag, Bluetooth low energy, ANT+, and proprietary 2.4GHz applications in the building automation and automotive sectors. The development kit enables engineers to work with the module and rapidly come up with tested and verified solution for a range of applications. Development is further eased by Nordic’s nRF52 Series software architecture which cleanly separates the Bluetooth low energy RF protocol software from the developer’s application code eliminating the risk of protocol corruption.

The nRF52832 SoC’s high performance 64MHz, 32-bit ARM® Cortex® M4F processor, along with a full range of programmable on-chip analog and digital peripherals that reduce demand on the processor’s resources, ensures the module can power even the most complex wireless applications. Delta Electronics says the module is particularly suited to building automation applications such as security and automotive applications such as keyless entry and electric vehicle charging systems where connectivity with Bluetooth LE 4.0 (and later) smartphone and tablet-based apps is an advantage.

Nordic’s nRF52832 Bluetooth low energy SoC, a member of Nordic Semiconductor’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines the ARM Cortex M4F processor with a 2.4GHz multiprotocol radio (fully compatible with Bluetooth 4.2, ANT™, and proprietary 2.4GHz RF software) capable of -96 dB RX sensitivity, with 512 kB Flash memory and 64 kB RAM. When launched, the SoC was the world’s highest performance single-chip Bluetooth low energy solution, delivering up to 60 percent more generic processing power, offering 10 times the Floating Point performance and twice the DSP performance compared to competing solutions. The nRF52832 SoC also features a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series and an NFC™ tag for consumer-friendly Touch-to-Pair.

“We chose the nRF52832 primarily because the ARM Cortex M4F processor has ample power to deal with the most complex sensor algorithms,” says Sog Yang, Senior Marketing Manager – Connectivity, Delta Electronics. “The ultra low power characteristics and the SoC’s built-in NFC-A tag, plus Nordic’s excellent technical support, were also important in swaying our decision to select the company as our design partner.”
