The nRF54L Series of wireless SoCs developed by Nordic Semiconductor expects to find homes in all sorts of Bluetooth LE (BLE) and IoT applications. According to the company, they bring new levels of enhanced efficiency and exceptional processing power. Each of the three new SoCs packs a 2.4-GHz radio and MCU functionality, including CPU, memory, and peripherals, into a single ultra-low-power chip that can be utilized for simple, high-volume products as well as more advanced designs.
“This new range of wireless SoCs establishes Nordic, already the world’s leading supplier of Bluetooth LE solutions, firmly at the forefront of low-power wireless technology,” said Oyvind Strom, EVP Short-Range at Nordic Semiconductor. “Expanding the product series with the nRF54L10 and nRF54L05, alongside the nRF54L15, allows us to support a wide range of Bluetooth LE and IoT applications with greater flexibility and exceptional energy efficiency.”
The nRF54L15, nRF54L10, and nRF54L05 all come equipped with the same Arm Cortex-M33 processor (clocked at 128 MHz) and a BLE ultra-low-power 2.4G Hz radio. Each has a varying amount of RAM, with the nRF54L15 equipped with 1.5-MB non-volatile memory (NVM) and 256-kB RAM, the nRF54L10 with 1.0-MB NVM and 192-kB RAM, and the nRF54L05 with 0.5-MB NVM and 96-kB RAM. All feature up to 35 GPIOs and come in an ultra-compact 2.4- × 2.2-mm WLCSP package option that’s 50% smaller than Nordic’s nRF52840.
Nordic said the nRF54L Series supports a wide range of communication protocols, including BLE, Bluetooth Mesh, Thread, Matter, Zigbee, Amazon Sidewalk, and 2.4-GHz proprietary protocols, with enhanced capabilities such as up to a 4-Mb/s data rate. This suits them for myriad applications, including wearables, smart rings, gaming controllers, medical devices, and more.
The nRF54L Series is available for sampling now, with full-volume production beginning toward the end of 2024.
