Ezurio Introduces New Modules for Next-Gen Low-Power Bluetooth LE, 802.15.4, and NFC Connectivity

Ezurio, a leader in wireless connectivity solutions, has introduced its latest ultra-compact BL54L15μ RF module series. Powered by Nordic Semiconductor’s advanced nRF54L15 SoC, this new series marks a significant advancement beyond Ezurio’s widely adopted nRF52-based modules, redefining Bluetooth® Low Energy (LE), 802.15.4 (Thread/Matter), and NFC solutions for next-generation embedded applications.

Unleashing enhanced processing power, expanded memory, and innovative peripherals, the BL54L15µ series stands as the ultimate choice for low-power connectivity in space-constrained applications. With a 128 MHz ARM Cortex-M33 processor, a 128 MHz RISC-V coprocessor, 1.5 MB of non-volatile memory, and 256 KB of RAM, the modules double the processing power of their predecessors, like the BL654 based on the nRF52840. The BL54L15µ series operating at a frequency of 2.402- 2.480 GHz maximizes the capabilities of the nRF54L15 hardware, including +8 dBm transmit power, a wide 1.7V–3.6V voltage range, and integrated NFC A-Tag functionality.

Designed with a compact 6.3 x 7.9 mm footprint, the BL54L15μ series delivers a groundbreaking combination of performance, efficiency, and security for Bluetooth LE, 802.15.4, and NFC applications. Engineered for hostless operation, these modules are ideal for highly integrated applications, providing flexible software support through Canvas Software Suite, Nordic nRF Connect SDK, and Zephyr RTOS.

Security is a core strength of the BL54L15μ, with design architecture targeted at PSA Certified Level 3, offering Secure Boot, Secure Firmware Update, Secure Storage, and physical attack protection through advanced tamper detection and hardened cryptographic accelerators.

Key Features of BL54L15 Series

• Best in Class Multiprotocol Radio: Best-in-class multiprotocol radio with up to +8 dBm TX power (1 dB steps) and -98 dBm RX sensitivity for 1 Mbps BLE. Supports Bluetooth 5.4, upcoming Bluetooth specifications, Bluetooth Mesh, Thread, and Matter.
• Advanced Security: Designed for PSA Certified Level 3 with Secure Boot, Secure Firmware Update, and Secure Storage. Integrated tamper sensors detect physical attacks and respond, while cryptographic accelerators are hardened against side-channel vulnerabilities.
• True Industrial Operating Range: Built and certified for a full industrial operating range of -40 ºC to +105 ºC, using components selected to withstand extreme conditions.
• Regulatory Approvals – In the process of obtaining modular certifications, including FCC, ISED, EU, RCM, MIC, and KC for Bluetooth & 802.15.4 compliance.

The BL54L15μ series is powered by Nordic’s advanced nRF54L15 SoC, housed in a compact 2.4 x 2.25 mm WLCSP package, utilizing 32 GPIOs.The platform integrates high-speed peripherals, including HS-SPI/UART, software-defined peripherals on the VPR core, and a 64 MHz GPIO port supporting 11 GPIOs. It also features an extensive suite of low-leakage peripherals, such as dual QDEC, seven timers, a global RTC, dual watchdog timers, NFC A-Tag interface, temperature sensor, I2S, comparator, three PWM channels, low-power comparator, a 14-bit 8-channel ADC, and multiple TWI/SPI/UART interfaces—all accessible across 32 GPIOs at 1.7–3.6V operating range. Developers can choose between an integrated pre-certified chip antenna or an external antenna via trace pad, all within an ultra-compact footprint of just 6.3 mm x 7.9 mm x 1.75 mm. Designed for rugged environments, it supports an extended industrial temperature range from -40°C to +105°C.

The BL54L15μ supports advanced Bluetooth LE capabilities, including Peripheral/Central modes, 2 Mbps high-throughput, LE Coded PHY for long-range, Angle of Arrival (AoA)/Angle of Departure (AoD), and Bluetooth Mesh networking. It also supports Firmware Over-the-Air (FOTA) updates via MCUboot and Zephyr, ensuring seamless in-field updates. With hostless operation enabled by the multi-core architecture, system complexity and BOM cost are significantly reduced. Fully featured development kits are available to accelerate time to market. Additionally, the module delivers transmit power up to +8 dBm (adjustable in 1 dB steps) and a receive sensitivity of up to -106 dBm, ensuring robust wireless performance in demanding environments.

The BL54L15μ series is specifically engineered to serve a wide array of markets—from connected medical devices and secure building automation systems to mission-critical industrial sensors. Its robust performance, compact design, and advanced security features make it an ideal choice for next-generation low-power wireless applications.
