Nordic's New nRF51 Series ULP Wireless SoCs Slash Power Consumption, up RF Performance, and Free Designers from Proprietary Software Frameworks

Jun 28, 2012

Oslo, Norway – June 28, 2012 – Ultra low power (ULP) RF specialist Nordic Semiconductor ASA (OSE: NOD) today announces the first members of its new nRF51 Series of ultra-low power (ULP) RF integrated circuits (ICs) that feature a new multi-protocol 2.4GHz radio and a 32-bit ARM® Cortex™-M0 based processor. Nordic’s novel software architecture for Bluetooth® low energy and ANT™ System-on-Chip (SoC) solutions frees designers from the integration effort, complexities, and restrictions of chip vendor-supplied software frameworks and instead allows customers to develop their designs quickly and easily using the highly popular and familiar ARM Cortex programming environment.

This major benefit is achieved by using a new and novel software architecture featuring a unique and powerful separation between protocol stack and user application code. This separation provides developers a clean boundary between application and protocol stack, and removes the need to struggle with integration of application code as part of a vendor-imposed application development framework. Code development is now greatly simplified and accelerated and at the same time risks associated with integration of application and stack code are significantly reduced. Customers can expect lower bug rates and improved robustness for their applications.

With the launch of the Nordic Semiconductor nRF51 Series, developing applications based on class-leading devices from any of the three main ULP wireless sub-categories – Bluetooth low energy, ANT / ANT+™, and 2.4GHz proprietary RF – has never been so straightforward or accessible to the widest possible range of developers.

The first two Flash-based ICs to debut in the new nRF51 Series (see 'About the nRF51 Series' below) are the nRF51822 multi-protocol Bluetooth low energy / 2.4GHz proprietary RF SoC (see 'About the nRF51822' below), and the nRF51422 – the world’s first ANT SoC (see 'About the nRF51422' below).
“We have worked closely with our most trusted customers for several years on the nRF51 Series and we are confident that this latest Nordic product range once again sets a new benchmark for Bluetooth low energy, ANT, and 2.4GHz RF proprietary ultra low power applications,” comments Thomas Embla Bonnerud, Director of Product Management at Nordic Semiconductor.
About the nRF51 Series

The new multi-protocol 2.4GHz radio provides an unprecedented combination of high-performance, ultra low power consumption, and flexibility. Key features and benefits of the radio include:
  • -92.5dB RX sensitivity in Bluetooth low energy mode;
  • Up to +4dBm output power in all modes;
  • Up to 9.5dBm improvement in link budget compared to Nordic’s previous generation radio;
  • Sub-10mA peak currents running off a 3V coin cell battery;
  • Bluetooth low energy (Bluetooth v4.0) compliant;
  • 100% on air compatibility with Nordic's existing nRF24L series ICs;
  • Support for non-concurrent and concurrent operation of a range of protocols including Bluetooth low energy, ANT, and proprietary 2.4GHz RF;
  • Full range received signal strength indication (RSSI).
