Overview

The nRF52811-QCAA-R is a versatile, ultra-low power multiprotocol SoC designed for cost-sensitive Bluetooth 5.1 and IEEE 802.15.4 applications. It features a 64 MHz ARM Cortex-M4 processor and includes an integrated 2.4 GHz transceiver with support for Direction Finding (AoA/AoD) and Thread protocols.

Why Choose This Part

The SoC offers exceptional RX sensitivity of -104 dBm and an on-chip balun for simplified RF front-end design. Its Programmable Peripheral Interconnect (PPI) allows peripherals to interact without CPU intervention, significantly reducing power consumption during routine operations.

Applications

Direction Finding Beacons
Utilizes Bluetooth 5.1 Angle of Arrival (AoA) and Angle of Departure (AoD) capabilities for precise indoor positioning.
Smart Home Sensors
Ideal for low-power window and door sensors using Thread or Zigbee-lite via IEEE 802.15.4.
Wireless HID
Serves as a high-efficiency controller for wireless mice, keyboards, and remote controls with multi-protocol support.
Asset Tracking
Deploys in battery-operated tags for logistics tracking, leveraging the 0.3 microamp shutdown current to maximize field life.
