NRF51802-QCAA-T

Product Overview

NRF51802-QCAA-T is a Nordic Bluetooth Low Energy RF transceiver SoC from Nordic Semiconductor ASA. It supports compact BLE designs where radio and application control are integrated in one IC. It is commonly selected for legacy BLE products, beacons, small sensors, accessories, remote controls and repair projects.

For design-in, continuation sourcing or repair work, engineers should review RF matching, antenna layout, interface timing, supply filtering and firmware compatibility. The selected orderable code should also be checked for package footprint, firmware or stack support, RF band, regulatory requirements and lifecycle status before approval.
