Nordic’s cellular IoT module gains Arm Platform Security Architecture (PSA) certification scheme， PSA Certified Level 1 certification to improve IoT protection assurances and_accelerate IoT device deployment
Nordic Semiconductor’s recently launched nRF9160? System-in-Package (SiP) LTE-M/NB-IoT cellular IoT module is among the first products to be awarded PSA Certified? Level 1 certification under a new IoT security initiative spearheaded by Arm.
PSA Certified provides a simple and_comprehensive approach to security testing. It comprises two elements: a multi-level， security robustness scheme (Levels 1，2 and_3) and_a developer focused API test suite. PSA Certified enables devices makers to achieve the security required for their use case through these three progressive levels of security assurance， each requiring increasingly rigorous hardware and_software evaluation， which are assigned by analyzing the use case threat vectors.
Nordic is providing highly integrated Arm-based cellular IoT solutions and_is among the first of our partners to deliver a Level 1 PSA Certified solution with the nRF9160 SiP cellular IoT module
Paul Williamson， Arm.
“Nordic’s nRF9160 SiP cellular IoT module was designed from the outset to embrace the highest levels of security and_PSA certification is an important independent verification of our commitment to that strategy，” says Svein-Egil Nielsen， CTO of Nordic Semiconductor. “While certification further reinforces customers’ confidence that the nRF9160 SiP is well protected， the product will form only one part of the IoT. As a leader in the IoT sector， Arm and_its test lab partners are well placed to build confidence in the security of the whole IoT ecosystem through PSA Certified and_Nordic Semiconductor is excited to partner with them in this important initiative.”
“In a world of a trillion connected devices trust is essential， and_it’s our industry’s responsibility to enable this trust，” said Paul Williamson， VP and_GM， Emerging Business Group at Arm. “PSA Certified enables IoT solution developers and_device makers to verify their solutions have been designed with a secure foundation， in line with PSA principles. Nordic is providing highly integrated Arm?-based cellular IoT solutions and_is among the first of our partners to deliver a Level 1 PSA Certified solution with the nRF9160 SiP cellular IoT module.”
Nordic Semiconductor’s nRF9160 SiP cellular IoT module is based on an Arm? Cortex?-M33 CPU core and_is the first in its class to incorporate Arm TrustZone? and_Arm CryptoCell security for Internet-level encryption and_application protection. The use of this Arm technology in Nordic’s nRF9160 eased the path to Level 1 because it already encompassed a lot of the security requirements demanded by the certification.

ABOUTNORDIC NEW APP
The nRF5340 combines a high performance application processor with a fully programmable， ultra low power network processor， plus advanced root-of-trust and_trusted execution security features， into a low power multiprotocol SoC ready for professional lighting， industrial automation， advanced wearables， and_other complex IoT applications
Nordic Semiconductor today announces the nRF5340TM high-end multiprotocol System-on-Chip (SoC)， the first member of its next generation of nRF5 Series SoCs. The nRF5340 builds on Nordic’s proven and_globally adopted nRF51 and_nRF52 Series multiprotocol SoCs while introducing a new flexible， dual-processor hardware architecture with advanced security features. The nRF5340 supports major RF protocols including Bluetooth? 5.1/Bluetooth Low Energy (Bluetooth LE)， Bluetooth mesh， Thread， and_Zigbee.
The nRF5340 SoC is designed for extended operating temperature up to 105oC， which together with its multiprotocol support and_advanced security features makes it ideally suited for professional lighting and_industrial applications. Further， the SoC meets the demands of next generation sophisticated wearables with its high performance application processor matched to a generous 512 KB of RAM. The QSPI peripheral is augmented to interface with external memory at 96 MHz， and_a 32 MHz High Speed SPI peripheral is integrated to interface with displays and_complex sensors.
The nRF5340 and_nRF Connect SDK combine to make it easy for developers to build wireless applications that until now were impossible.

The nRF5340 incorporates Arm CryptoCell-312， Arm TrustZone? technology， and_Secure Key Storage for the highest level of security. With Arm CryptoCell-312 the most common Internet encryption standards are hardware accelerated and_Arm TrustZone provides system-wide hardware isolation for trusted software by creating secure and_non-secure code execution areas on a single core. The nRF5340’s combined security features enable advanced root-of-trust and_secure firmware updates while protecting the SoC from malicious attack.
The nRF5340 is based around dual Arm? Cortex?-M33 processors;_a high performance application processor running up to 128 MHz (510 CoreMark) with dedicated 1 MB Flash and_512 KB RAM， and_a fully programmable， ultra low power network processor running at 64 MHz (238 CoreMark) with dedicated 256 KB Flash and_64 KB RAM. The powerful application processor is very efficient (65 CoreMark/mA)， has an 8 KB 2-way associative cache， is DSP and_floating point capable and_offers voltage and_frequency scaling options. The application processor integrates the Arm Cryptocell-312， Arm TrustZone， and_Secure Key Storage advanced security features， plus a wide range of interface peripherals including NFC， USB， QSPI， and_High Speed SPI. The fully programmable network processor is even more efficient (101 CoreMark/mA) and_is optimized for low power during radio operation and_low duty-cycle sensor data collection. Programmable access to the network processor offers optimal implementation of proprietary 2.4 GHz protocols， ensuring portability from the nRF51 and_nRF52 Series.
The nRF5340 incorporates a new， power-optimized multiprotocol 2.4 GHz radio with a TX current of 3.2 mA (0 dBm TX power， 3 V， DC/DC) and_RX current of 2.6 mA (3 V， DC/DC). Sleep current is as low as 1.1 μA. The SoC features enhanced dynamic multiprotocol support enabling concurrent Bluetooth LE and_Bluetooth mesh/Thread/Zigbee operation for provisioning/commissioning and_interaction with a mesh network from a smartphone using Bluetooth LE. The radio is capable of all Bluetooth 5.1 Direction Finding features. The nRF5340 operates over a 1.7 to 5.5 V supply voltage range， allowing supply from rechargeable batteries and_USB. The SoC integrates XTAL load capacitors for both 32 MHz and_32.762 kHz crystals， lowering by four the number of external components required compared with Nordic’s nRF52 Series - reducing both bill-of-materials (BOM) and_solution size.
The nRF5340’s software development kit， the nRF Connect SDK， offers a complete solution that integrates the Zephyr RTOS， a Bluetooth LE protocol stack， application examples， and_hardware drivers. The nRF Connect SDK is a proven solution used in the development of commercial products based on the nRF9160 System-in-Package (SiP). Now with added support for the nRF5340， the SDK unifies low power cellular IoT and_low power， short range wireless development. The nRF Connect SDK is publicly hosted on GitHub， offers source code management with Git and_comes with free SEGGER Embedded Studio IDE support. Nordic has also launched the nRF5340 PDK， an affordable， single board preview development kit for the nRF5340. The nRF5340 PDK makes all of the nRF5340’s features and_GPIOs available to the developer and_comes with an on-board SEGGER J-Link debugger for programming and_debugging the SoC.
“Bluetooth， Thread， Zigbee and_other low power wireless technologies now form a critical part of the IoT. Developers are already working on tomorrow’s commercial products based on highly-complex applications such as property tech， location services， medical， smart home， and_Industrial IoT. These demand_greater computational power with high security， yet developers expect Nordic’s wireless solutions to remain compact and_highly energy-efficient，” says Kjetil Holstad， Director of Product Management at Nordic Semiconductor.
“The nRF5340 SoC is designed to meet these needs and_more. The product is the culmination of Nordic’s decades of experience in ultra low power wireless， the lessons learned from the development and_support of the nRF51 and_nRF52 Series over the last seven years， and_several years of focused product development from perhaps the most experienced low power wireless R&D team in the world. The nRF5340 and_nRF Connect SDK combine to make it easy for developers to build wireless applications that until now were impossible.”
The nRF5340 PDK is available now through Nordic’s distribution network. nRF5340 SoC engineering samples will be available soon in a 7x7 mm aQFN package with 48 GPIOs.
