NRF51824-QFAA-R

The nRF51824 incorporates a 32-bit Cortex-M0 processor enabling demanding automotive sensor applications to be realized in a single chip solution.

nRF51824 is a flash-based wireless SoC. Flash brings the added benefits of flexibility in development and significant appeal of Over The Air Device Firmware Upgrades (OTA DFU) This allows for products using the nRF51824 to upgrade their firmware (application and protocol stack) after production when out in the field.

The 2.4GHz radio supports multiple protocols including Bluetooth low energy, ANT and 2.4GHz proprietary. The radio has high definition RSSI and highly automated functionality, including EasyDMA for direct memory access during packet send and retrieve.

The nRF51824 SoC is an extremely power efficient device that can run from a supply between 1.7V and 3.6V. All individual peripherals and clocks offer complete flexibility of power down when not required for task operation thus minimizing power consumption to a minimum. The IC has a comprehensive system of automated and adaptive power management features. These features range across the entire IC’s operation from power supply switching to peripheral bus/EasyDMA memory management, to automated shut down of all but the absolute essential peripherals required to perform a task.

Nordic Semiconductor offers an extensive range of freely-available software to support its wireless SoCs. The support offering comes in the form of wireless protocol stacks for Bluetooth low energy, ANT and 2.4GHz proprietary and are known as SoftDevices. SoftDevices are pre-compiled, pre-linked binary files. SoftDevices can be programmed in nRF51 series SoCs and are downloadable from the Nordic website.

The nRF5 SDK is also provided, nRF5 SDKs offer numerous software examples and modules to assist and speed up your development cycle on the nRF51824.
