Redefining Efficiency with the nRF54L15 and nPM2100

As demand for ultra-low power solutions continues to rise across industries, Nordic Semiconductor continues to set the standard in power efficiency with a broad portfolio of Bluetooth® Low Energy (LE) and ultra-low power solutions. With 1.5 MB of non-volatile memory (NVM) and 256 KB RAM, the nRF54L15 wireless SoC stands out as the largest memory option of Nordic’s nRF54L Series. In addition to advanced memory capacity, the nRF54L15 delivers exceptional power efficiency, multiprotocol support, and cost-optimized performance for today’s most demanding applications.

Packing comprehensive efficiency into one single solution, Nordic’s nPM2100 is the industry’s first PMIC purpose-built to support most primary cell battery chemistries. It delivers hyper-efficient standby power, accurate battery gauging, and a 35nA Ship Mode for simplified shipping and storage without the risk of deep cell discharge.

Designed for inherent efficiency, the nRF54L15 is ideal for applications with frequent wakeups. For applications with longer idle periods, pairing nRF54L Series SoCs with the nPM2100 PMIC unlocks even greater power savings. The nPM2100’s dedicated hibernate mode delivers lower average current consumption at wakeup intervals of 85s or longer, helping to extend battery life by up to 3x in extended inactive periods.

High Capacity Memory Solutions with the nRF54L15

As the largest memory variant of Nordic’s nRF54L Series, the nRF54L15 is an optimal solution for a broad range of demanding wireless applications. With 1.5 MB NVM and 256 KB RAM, the nRF54L15 is a high-capacity memory solution that’s still cost-optimized for high-volume projects. It utilizes an ultra-low power, multiprotocol 2.4 GHz radio that supports Bluetooth® 6.0 features, including Channel Sounding for precise location capabilities.

The nRF54L15 SoC also supports IEEE 802.15.4-2020, Thread, Matter, and Zigbee standards.Ideal for designs that demand a compact footprint that doesn’t compromise on performance, the nRF54L15 integrates a 128 MHz Arm® Cortex®-M33 processor and a comprehensive peripheral set.

Additionally, the nRF54L15 development kit serves as a comprehensive, cost-friendly single-board devkit that encompasses the full potential of the SoC with the support of Nordic’s extensive nRF Connect tools. Acting as the dev kit for all three wireless in the nRF54L Series, the nRF54L15 sits on the board while the nRF54L10 and nRF54L05 can be emulated

Precision Power for Primary Cell Batteries with the nPM2100 PMIC

Primary cell batteries are go-to options for applications requiring extended shelf life, convenient deployment, minimal maintenance, and especially in scenarios where recharging isn’t feasible. However, managing power efficiently in these power-constrained environments requires more than just low power components. It demands intelligent regulation so that lifecycles can last longer in between each power swap.

Engineered to support designs with non-rechargeable batteries, the nPM2100 is a feature-rich PMIC with a comprehensive suite of advanced power-saving capabilities. Leveraging a high-efficiency boost converter, output voltages from 1.8 V to 3.3 V, and input support ranging from 0.7 V to 3.4 V, it enables longer run-time on every battery.

Integrating one of the most efficient boost converters on the market, the nPM2100 utilizes a 150 nA IQ internal boost regulator. Its hibernate mode includes a wakeup timer that maintains system readiness while bringing standby current down to 175 nA, supporting designs that prioritize deep sleep functionality.

The nPM2100 also enhances battery accuracy with a host-processed fuel-gauge that factors in both voltage and temperature. Unlike conventional voltage-only methods, this approach minimizes inaccurate battery readings to prevent premature replacements and unexpected shutdowns.

Power Pairing the nPM2100 with nRF54L Solutions

Pairing the nPM2100 with nRF54L solutions enables next-level energy efficiency. The nPM2100’s hibernation mode can achieve up to 3x longer battery life in applications that remain idle for long periods and only activate intermittently.
