NRF52832-QFAA-T

RF Transceiver ICS Overview

The NRF52832-QFAA-T is a Bluetooth Low Energy system-on-chip from Nordic Semiconductor, featuring an ARM Cortex-M4 core with FPU operating at 64 MHz. It integrates a 2.4 GHz transceiver supporting up to 2 Mbps data rates and +4 dBm output power, with -96 dBm sensitivity. The device includes 512 KB Flash and 64 KB RAM, operates between 1.7 V and 3.6 V, and supports BLE, Bluetooth Mesh, NFC-A, ANT, and proprietary protocols within a -40°C to +85°C range in a 48-pin QFN package.

RF Transceiver ICS Feature Summary

• Supports concurrent operation of Bluetooth LE and Bluetooth Mesh for advanced network control
• Integrates NFC-A tag functionality for simplified pairing and payment solutions
• Includes digital audio interfaces such as PDM and I2S for microphone and audio applications

RF Transceiver ICS Applications

• Wearable devices requiring low power consumption
• Smart home sensors and actuators
• Medical electronic monitoring equipment
• Asset tracking tags
• Industrial IoT nodes

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'T' against official Nordic documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with required SoftDevices like S132 or S140 for intended protocol support. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before ordering.

RF Transceiver ICS Selection Notes

Select this model when concurrent Bluetooth LE and Mesh capabilities are required alongside NFC-A support. The 512 KB Flash and 64 KB RAM configuration suits complex firmware needs. Consider the 48-pin QFN package constraints for PCB layout and thermal management during design.

RF Transceiver ICS Part Context

Part of the nRF52 series, succeeding the nRF51 family with enhanced processing power via the Cortex-M4F core. It bridges the gap between basic BLE chips and higher-end multi-protocol SoCs like the nRF52840, offering a balance of performance and cost for mid-range IoT applications.

RF Transceiver ICS Replacement Considerations

nRF52832-QFAA-G-R7 serves as a direct functional equivalent with identical electrical characteristics but differs in reel packaging quantity. Verify pinout and register compatibility if substituting between different tape/reel variants within the same base part number.
