nRF51824数据手册Nordic中文资料规格书

描述 Description

The nRF51824 chip is an ultra-low power 2.4 GHz wireless System on Chip (SoC) integrating the nRF51 Series 2.4GHz transceiver,a 32 bit ARM? Cortex\"*-MO CPU, flash memory, and analog and digital peripherals. nRF51824 can support Bluetooth? low energy and a range of proprietary 2.4 GHz protocols, such as Gazell from Nordic Semiconductor.\r
\r
The nRF51824 chip is fully qualified in accordance to AEC-Q100 Grade 2 specifications.\r
\r
Fully qualified Bluetooth low energy stacks for nRF51824 are implemented in the S1x0 series of SoftDevices.The S1x0 series of SoftDevices are available for free and can be downloaded and installed on nRF51824 independent of your own application code.
