Nordic Semiconductor

Nordic Semiconductor is the Oslo-based wireless specialist behind the Bluetooth Low Energy chips in a generation of wearables and beacons, and the profiles here cover its two product lines. The Bluetooth side has the nRF52840 and nRF52832 multiprotocol SoCs — ARM Cortex-M4 parts with on-chip radios for Bluetooth 5, Thread, Zigbee and proprietary 2.4 GHz links, stocked in QFN packages with tape-and-reel ordering codes. The proprietary side has the nRF24L01P-T, the classic 2.4 GHz GFSK transceiver in 4×4 mm QFN-20 on tray, but note the lifecycle reality: Nordic marks the whole nRF24 series Not recommended for new designs, so new programs should pick the nRF52 Bluetooth parts or a current proprietary-radio alternative. Wireless selection turns on protocol, data rate and antenna interface — confirm the complete ordering code including the packing suffix, since tray, reel and sample-box variants are different orderable parts.

Sourcing notes for Nordic Semiconductor parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
