NRF52832-QFAB-R

RF Transceiver ICS Overview

The nRF52832-QFAB-R is a Bluetooth Low Energy system-on-chip from Nordic Semiconductor, featuring an Arm Cortex-M4 core with FPU. It supports Bluetooth 4.2 and 5, operating at 2.4 GHz with a maximum data rate of 2 Mbps. The device provides 256 KB of program memory and operates within a supply voltage range of 1.7 V to 3.6 V. Key electrical parameters include a transmit power of 4 dBm, receiver sensitivity of -96 dBm, receive current of 5.4 mA, and transmit current of 5.3 mA. It utilizes a QFN48 package.

RF Transceiver ICS Feature Summary

• Supports Bluetooth 4.2 and Bluetooth 5 protocols
• Integrates NFC-A tag functionality for simplified pairing
• Includes adaptive power management for low energy consumption

RF Transceiver ICS Applications

• Bluetooth beacon devices
• Smart home controllers
• Wearable health monitors
• Remote control units

RF Transceiver ICS Procurement Notes

Verify the specific protocol stack version supported by this variant, as it differs from newer QFAB-G-R models that support Bluetooth 5.3. Confirm package compatibility with reference layouts regarding errata workarounds for unused pins. Ensure design accounts for the 256 KB flash limitation compared to higher capacity variants.

RF Transceiver ICS Selection Notes

Select this model when Bluetooth 4.2 or 5 compliance is sufficient and 256 KB flash meets application requirements. Consider the QFAB-G-R variant if Bluetooth 5.3 features are needed. Evaluate the QFAA variant for different package configurations. This SoC suits applications requiring concurrent BLE and Mesh operations with moderate memory needs.

RF Transceiver ICS Part Context

Part of the nRF52 series, the nRF52832-QFAB-R serves as a versatile multiprotocol solution. It builds upon previous generations like the nRF52810 and nRF52805, offering enhanced memory and peripheral sets. It is designed for complex IoT applications requiring high performance and low power efficiency in a compact form factor.

RF Transceiver ICS Replacement Considerations

NRF52832-QFAB-G-R: Supports Bluetooth 5.3 instead of 4.2/5. NRF52832-QFAA-G-R: Different package type (QFAA) with Bluetooth 5.3 support.
