BLE Fitness Tracker

Cost-effective Bluetooth 5.4 SoC with 512KB Flash and 64KB RAM, ideal for wearables, beacons, and low-power sensor applications.

Full-featured BLE 5.4 + 802.15.4 SoC with 512KB Flash, 128KB RAM, USB, and NFC. Offers extended-range BLE (Coded PHY) and mid-range capability between nRF52832 and nRF52840.

Advanced multiprotocol SoC with 1MB Flash, 256KB RAM, and USB support. The go-to chip for Bluetooth 5.4, Thread, Zigbee, and 802.15.4 applications.

Mid-range nRF54L series SoC combining ARM Cortex-M33 with a RISC-V co-processor. 1MB Flash and 128KB RAM with BLE 5.4, targeting wearables and connected sensors.

Next-generation ultra-low-power Bluetooth 5.4 SoC with RISC-V and ARM Cortex-M33 cores. Designed for ultra-constrained battery-powered devices.

The flagship nRF54L series SoC built on a 22nm process, featuring a 128 MHz ARM Cortex-M33 + RISC-V co-processor with 2MB Flash and 512KB RAM — the largest memory in the nRF54L family. Supports Bluetooth LE, Matter, Thread, Zigbee, and 2.4 GHz proprietary protocols up to 4 Mbps. The nRF54LM20A variant adds 66 GPIOs and high-speed USB; the nRF54LM20B adds an integrated Axon NPU for hardware-accelerated Edge AI inference. Security includes TrustZone, CRACEN cryptographic engine with side-channel protection, and tamper detection.

Build a Bluetooth LE fitness tracker with extended-range BLE using the nRF52833 — tracking activity, heart rate, and sleep with reliable connectivity at the edge of standard BLE range.

Build a high-end BLE fitness tracker with the nRF54LM20 — the most capable nRF54L chip offering 2MB Flash for rich GATT services, sensor fusion, and OTA DFU with ultra-low standby current.

Build an ultra-low-power BLE fitness tracker with the nRF54L15 — leveraging CRACEN hardware security, RISC-V co-processor for always-on sensing, and BLE 5.4 for multi-day battery life.
