Nordic Semiconductor has recently unveiled the 128 MHz nRF54L15 Cortex-M33 multi-protocol wireless microcontroller, the first from the nRF54L Series, and the second from the wider nRF54 family after the more powerful 320 MHz nRF54H20 dual-core Cortex-M33 MCU was introduced last Spring.
While the nRF54H20 was designed to enable new types of IoT devices with a leap in performance and lots of resources with up to 2 MB flash and 1MB SRAM, the new nRF54L15 aims to be an upgrade to the nRF52 series with twice the performance and much better power efficiency, with for instance, half the Rx power consumption over its predecessor.
Nordic Semi nRF54L15 key features and specifications:
- Arm Cortex-M33 @ up to 128 MHz with up to 1.5 MB Flash + 256 KB SRAM
- RISC-V coprocessor for “software-defined peripheral”
- New peripherals
- Global RTC
- 14-bit ADC
- Software-defined peripheral
- Designed for PSA Certified Level 3 IoT security standard
- TrustZone isolation, side-channel protection, and tamper detection
- Power consumption – Rx current consumption is half that of the nRF52840
- Packages – QFN48 (6×6 mm) and WLCSP (2.4×2.2 mm)
- Manufacturing process – TSMC’s 22ULL (22 nm) process technology
The nRF54L15 is designed for high-volume wireless IoT products such as PC accessories, gaming controllers, remote controls, virtual reality and augmented reality devices, Smart Home appliances with Matter support, medical devices, and various industrial IoT applications.
Nordic Semi says the nRF54L15 is available for sampling in the QFN48 package with 31 GPIOs now, but the company also plans to soon launch two ultra-compact WLCSP packages with a 2.4×2.2mm footprint that will be more than 50 % smaller than nRF52840 for designs with strict size constraints. One of the WLCSP packages will offer 32 GPIOs with a 0.3mm pitch, and the other will feature 14 GPIOs with a 0.35mm pitch.
This is an early announcement and the detailed features and specifications have not been released publicly just yet, and people needing more details need to contact their local Nordic sales representative at this time. Eventually, all you need to get started should be made available on the product page, and the press release may also have a few extra tidbits of information.
