nRF52832-QFAA-T
Overview
The nRF52832-QFAA-T is a high-performance Bluetooth 5.3 SoC integrating a 64MHz ARM Cortex-M4 with a Floating Point Unit (FPU). It combines a 2.4GHz multiprotocol radio with 512kB Flash and 64kB RAM, making it a standard choice for power-constrained wireless applications requiring local processing.
Why Choose This Part
The SoC features an extremely low power architecture with a sleep current of approximately 0.7uA and a TX current of 5.3mA at 0 dBm using the internal DC/DC regulator. Its Cortex-M4F core provides significantly higher computational throughput than previous generation M0-based SoCs, allowing for more complex software stacks and sensor fusion.
Applications
Key Specifications
Getting Started
Development is best supported through the nRF5 SDK or the nRF Connect SDK based on the Zephyr RTOS. Engineers typically start with the nRF52-DK (PCA10040) development board, using Segger Embedded Studio or VS Code for firmware development via the integrated SWD interface.
