nRF52832-QFAA-G-R
Overview
The nRF52832-QFAA-G-R is a highly versatile, single-chip Bluetooth 5.3 SoC designed around a 64 MHz Arm Cortex-M4 processor with a floating-point unit (FPU). It integrates a 2.4GHz transceiver, 512kB Flash, and 64kB RAM, offering a balance of high-performance processing and low power consumption for complex wireless applications. The chip features an automatic power management system with an integrated DC/DC regulator to optimize efficiency during radio operations.
Why Choose This Part
The inclusion of a hardware FPU and DSP instructions allows for sophisticated on-chip data processing that typically requires higher-power processors. Its power management system is highly efficient, drawing only 0.3uA in system OFF mode and 9.2mA during 0 dBm TX, significantly extending the life of coin-cell operated devices.
Applications
Key Specifications
Getting Started
Start development with the nRF52-DK (PCA10040) development kit, which provides access to all I/Os and includes an onboard Segger J-Link debugger. Engineers should use the nRF Connect SDK or the legacy nRF5 SDK along with the SEGGER Embedded Studio or VS Code extensions for firmware development. The Nordic SoftDevice architecture simplifies the integration of the Bluetooth stack by separating the wireless protocol from the application code.
