Why Build Your Next Wireless Product on the nRF54 Series?

The nRF54 series consists of a power-saving MCU architecture provided with a multi-purpose 2.4 GHz radio, and current hardware security features. Ideal applications of nRF54 series include wearable devices, smart lock systems, medical equipment, systems for building management, asset tracking, industrial monitoring systems, and Matter-related devices.

The nRF54L15 integrates a Cortex-M33 processor with a working frequency of 128 MHz, 1.5 MB of non-volatile memory, and a 256 KB RAM. It supports technologies like Bluetooth LE, Bluetooth Mesh, Matter, Thread, Zigbee, proprietary 2.4 GHz transmission, and Bluetooth Sounding.

A coprocessor that operates at the frequency of 128 MHz can manage low-level tasks that are time-bound in nature. Nordic claims that the current for radio is as low as 3.4 mA when it comes to receiving while 4.8 mA is required for the transmission process at 0 dBm, which makes the product appealing for use in devices that will be powered for months or even years from a small-sized battery.

The nRF54H200 series is aimed at high-end applications. It features multiple processors that operate at the frequency of 320 MHz using multiple RISC-V processors along with 2 MB of non-volatile memory and 1 MB of RAM. Its peripherals also provide 480 Mbps of high-speed USB, CAN FD and 1 state of the art memory converter.

With the ability to transmit up to +10 dBm and receive signals at sensitivities of -99 dBm for Bluetooth LE and -104 dBm for IEEE 802.15.4, this technology is a great choice for products requiring powerful computing, audio gadgets, gateways, industrial machines, and sophisticated wearables.

nRF54L15 or nRF54H20: Which One Should You Choose?

Product requirement Recommended starting point
Compact BLE sensor, tag, lock or wearable nRF54L15
Matter-over-Thread end device nRF54L15
Cost-sensitive, high-volume wireless product nRF54L15
Complex multicore application or heavy local processing nRF54H20
High-speed USB or CAN FD requirement nRF54H20
Audio, advanced HMI or large real-time data pipelines nRF54H20

This is a point to start, but not a replacement for measuring. We plan for flash, RAM, CPU, radio cycle, and power modes and test the stack using development hardware.

This avoids realizing too late that the process needs more RAM, a different antenna design, or different power supply rails.

Architecture of Products and Selection of Chips

We turn our ideas into quantifiable specifications, such as working time, distance, delay, capacity, sensors, safety, reconstructions, and price.

Our specialists analyze the two required Systems on Chip (SoC) and important Nordic chips and decide on earlier mentioned components and their place in a system of devices, mobile phone, gateway, and cloud service. If we consider a product that needs to be charged, we could use either the nPM1300 or nPM1304 chips.

Custom PCB Design and RF Hardware

Our hardware work covers schematics, component selection, PCB layout, antenna matching, stack-up, power regulation, battery charging, USB, debugging and design-for-manufacturing review.

We account for antenna keep-out, grounding, switching noise, sensor placement and enclosure materials early.

Projects can begin with a development kit or module and progress to a custom board. Deliverables may include PCB sources, Gerbers, pick-and-place data, BOM with alternates, assembly drawings and bring-up procedures. We also support EVT, DVT and production revisions.

Zephyr and nRF Connect SDK Firmware

We create advanced C/C++ firmware based on Nordic’s nRF Connect SDK and Zephyr RTOS. The work can involve the use of Devicetree, device drivers, threads, work queues, state machines, persistent configuration, watchdogs, recovery, logging and automated tests.

In case of the nRF54H20, we set up the access to the processor, the memory allocation, the communication between processors and the boot process.

When optimizing power usage we analyze the current traces. We analyze connection and connection intervals, sensor sampling, clocks, regulators, wake events, memory retention and peripheral leakage in order to draw up a power budget related to actual exploitation.

Bluetooth Low Energy and Bluetooth Mesh

Our BLE services include GAP/GATT architecture, standard or custom services, secure pairing, bonding, notifications, high-throughput transfers and firmware update. We develop iOS and Android companion apps and test reconnection, background behavior and version compatibility on real devices.

For Bluetooth Mesh, we can implement provisioning, node configuration, relay and friendship behavior, group control and device models. Where accurate ranging is part of the roadmap, we can assess nRF54L15 Bluetooth Channel Sounding against the required accuracy, antenna arrangement and product environment before committing to a positioning claim.

Matter and Thread Product Development

We build Matter-over-Thread devices such as locks, sensors, lighting controls, thermostats and building-automation nodes. Work includes Thread networking, commissioning over BLE, Matter data-model implementation, clusters and attributes, access control, persistent storage and over-the-air updates.

We can also integrate a border-router or cloud ecosystem where the commercial product requires it.

Test plans cover commissioning, fabric handling, credential reset, network loss, power interruption, OTA failure and targeted Matter ecosystems. Zigbee and proprietary 2.4 GHz firmware are available for applicable nRF54L15 designs.

Secure Boot, Identity of Devices and FOTA

One needs to realize that when it comes to encryption, that it only serves as a basis for building security measures. Devices must be defined in terms of assets, trust seams and attack vectors, followed by a very systematic implementation involving secure boot, firmware signing, protection of the keys, authenticated updates, a rollback strategy, controlling the debugging interface and provisioning for manufacturing.

The isolation provided by the TrustZone technology along with the crypto capabilities on nRF5x platform can make sure that sensitive operations are executed separately from the application code.

Also, it is crucial to design and implement a well-planned approach to how version control, deployment of updates, recovery of old firmware, logging errors, as well as responses to incidents should work together.

From Proof of Concept to Production

Our engagement moves through discovery, architecture, development-kit validation, PCB design, firmware, app or cloud integration, prototype bring-up, optimization, verification and manufacturing handover. Each stage has reviewable outputs and acceptance criteria. We test antenna, battery, component, OTA-recovery and interoperability risks before production.

Validation can include RF range, packet loss, power profiling, protocol traces, long-run stability, fault injection and hardware-in-the-loop tests. We support pre-compliance preparation and coordination with accredited laboratories.

Frequently Asked Questions

Can you migrate an existing nRF52 product to nRF54L15?

Certainly. The process starts with conducting an audit of code, memory, peripherals, protocols, and hardware. Considering the nRF54 development is based on nRF Connect SDK and Zephyr, the transfer becomes more of a challenge than merely exchanging components.

We rewrite drivers along with the application logic, design elements specific to each board and verify BLE performance and new power usage.

Does nRF54L15 support Matter and Thread simultaneously with BLE?

The nRF54L15 supports Bluetooth LE and IEEE 802.15.4 protocols including Thread and Matter. A common Matter design uses BLE for commissioning and Thread for operational networking. Actual concurrent behavior, memory use and performance depend on the selected SDK version and application configuration, which we validate against the product requirements.

Do you provide services only in terms of firmware development?

Absolutely. We can work alongside an existing hardware engineering team in terms of firmware, debugging or optimizing. Moreover, we can provide a complete source-to-finish development including architecture, PCB, firmware, mobile apps, cloud APIs, testing and delivery.
