NRF52840-CKAA-F-R7
Nordic SemiconductorNRF52840-CKAA-F-R7 is the Nordic nRF52840 multiprotocol SoC in the CK package variant — 3.544 x 3.607 mm WLCSP-94 — with the AA-F function variant (1024 KB flash, 256 KB RAM), supplied on 7-inch reel. Its advantage is the smallest nRF52840 footprint for space-constrained wearables, tags and medical patches: the same Bluetooth 5.4 LE / Thread / Zigbee / USB stack as the QFN variants in roughly one-third the board area. Selection advice: choose the CKAA only when board space forces it — WLCSP demands finer-pitch assembly, X-ray inspection and tighter PCB tolerances than the QFN-48 QFAA variant, and rework is effectively impossible; for prototypes and lower-volume builds the QFAA-F-R7 is the pragmatic pick.
