The embedded world is constantly evolving, with every new generation of microcontrollers (MCUs) pushing the boundaries of efficiency and performance. Nordic Semiconductor’s nRF54L Series is the latest in this evolution, offering a compelling upgrade from the widely adopted nRF52 Series. With twice the processing power, three times the efficiency, and a new ultra-low power multiprotocol radio, the nRF54L is built for next-generation designs. But does it justify switching from the nRF52? Let’s examine the key improvements.
Significant Gains in Processing Power and Efficiency
One of the most striking upgrades in the nRF54L is its twice-as-fast processing capability. The MCU can handle more intensive computations while consuming less energy, making it ideal for applications requiring AI/ML processing, edge computing, and real-time responsiveness.
To put this into perspective, a real-world test solving 1 million quadratic equations showed that the nRF54L completed the task in less than half the time required by the nRF52. Faster execution directly translates to lower power consumption, as the device spends less time in active processing mode.
Ultra-Low Power Multiprotocol Radio for Extended Battery Life
Wireless communication is often the biggest power drain in ultra-low power devices. The nRF54L introduces a new multiprotocol radio that delivers even lower power consumption than its predecessor.
A live demo comparing Bluetooth Low Energy (LE) advertising power consumption between the two MCUs showed a drop from 265 µA in the nRF52 to just 173 µA in the nRF54L—a substantial efficiency gain. Similarly, connection state power consumption was reduced by approximately one-third, ensuring longer battery life for wearables, IoT sensors, and other always-on devices.
Practical Cost-Effectiveness: More Performance at a Similar Price
The nRF54L isn’t just about better specs; it also maintains cost-effectiveness. Despite the significant improvements, pricing remains similar to the nRF52, meaning engineers can upgrade without major cost implications.
For those starting a new ultra-low power design, evaluating the nRF54L is a logical step. With its enhanced power efficiency, extended battery life, and improved computational ability, the upgrade presents a strong value proposition.
Making the Transition: Next Steps
For engineers and product designers considering the switch, the best way to evaluate the nRF54L is to get hands-on experience. Nordic Semiconductor provides development kits that allow designers to benchmark performance in real-world applications.
With ultra-low power consumption, higher efficiency, and seamless compatibility with existing Nordic Semiconductor ecosystems, the nRF54L is positioned to become the new standard for energy-efficient wireless designs.
