Nordic Semiconductor nRF52 Series-based Bluetooth low energy and NFC module offers ultra-compact wireless solution for smart cards and wearables
NXT-ID's 'IoT Stamp' module employs Nordic's nRF52832 SoC to deliver connectivity solution for space-constrained low power IoT applications
Nordic Semiconductor today announces that Melbourne, FL-based security technology company, NXT-ID (NASDAQ:NXTD), has selected Nordic’s nRF52832 Bluetooth® low energy System-on-Chip (SoC) to provide Bluetooth low energy and Near Field Communication (NFC™) wireless connectivity for its ‘IoT Stamp’ module. The module is designed for integration into wearables, portable devices, and Internet of Things (IoT) applications.
The IoT Stamp is said to have the smallest footprint of any combined Bluetooth low energy and NFC module on the market, suitable for ultra-compact, low energy applications, for example smartcards or smartwatches. The module is designed as a ‘drop-in’ solution to help manufacturers with little or no RF engineering expertise reduce development time and speed time-to-market for connected products. The module supports a range of personalized services including identity management, multifactor biometric authentication, and payment methods including Bluetooth low energy, NFC, and dynamic magnetic stripe.
The IoT Stamp can be used with a range of batteries from 10mAh to 480mAh or above. With a 10mAh battery the IoT Stamp can last for several months prior to recharge, thanks to the ultra low power operating characteristics of the nRF52832 SoC, as well as other low power techniques including motion activation, a low power touch control user interface, and patent pending ultra low power ‘buttonless’ wake-up technology.
Nordic’s nRF52832 Bluetooth low energy SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, has been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series SoCs. The result is a Bluetooth low energy solution which offers 58 CoreMark/mA, up to twice as power efficient as competing devices.
The nRF52832 SoC combines a 64MHz, 32-bit ARM® Cortex® M4F processor with a 2.4GHz multiprotocol radio (support for Bluetooth 5, ANT™ and proprietary 2.4GHz RF software) featuring -96dB RX sensitivity, with 512kB Flash memory, 64kB RAM, and an NFC-A tag for “Touch-to-Pair” operations. 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.
“We selected Nordic’s nRF52832 SoC because it provided us with both a Bluetooth low energy and NFC solution on a single chip, giving us a smaller footprint as well as the low power consumption we required,” says David Tunnell, NXT-ID CTO and Executive VP. “Moreover, Nordic’s technical support proved outstanding and the company’s engineers were always very responsive.”
NXT-ID has already partnered with travel and lifestyle community membership vendor WorldVentures to develop the flye smartcard which will be one of the first applications of the nRF52832-powered NXT-ID IoT Stamp. The flye smartcard can be used by WorldVentures’ 500,000 worldwide members for electronic payment, rewards, and other purposes. Users can load up to ten records—for example credit, debit, ID, and loyalty cards—on the ‘all-in-one’ smartcard.
