Overview

The nRF52811-CAAA-R is a highly compact, ultra-low power Bluetooth 5.3 SoC designed for cost-sensitive wireless applications. It features a 64 MHz ARM Cortex-M4 processor and supports advanced features like Direction Finding and IEEE 802.15.4 for Thread and Zigbee. This variant is provided in a 33-UFBGA WLCSP package, making it suitable for space-constrained wearable and industrial designs.

Why Choose This Part

It offers a high RX sensitivity of -104 dBm and a peak TX current of only 4.6 mA at 0 dBm, ensuring reliable range with exceptional battery life. The integration of 192kB Flash and 24kB RAM provides a balanced memory footprint for optimized wireless stacks and application code.

Applications

Bluetooth Direction Finding
Utilizes Angle-of-Arrival (AoA) and Angle-of-Departure (AoD) capabilities for high-precision indoor positioning and asset tracking.
Industrial IoT Sensors
Ideal for battery-operated wireless sensors requiring 802.15.4 or Bluetooth connectivity with minimal power consumption.
Smart Home Accessories
Enables Thread or Bluetooth LE connectivity in light switches, thermostats, and security sensors.
Low-Power Wearables
The WLCSP package and 1.4 uA sleep current support compact health trackers and disposable medical devices.
