Nordic Semiconductor nRF51422-QFAAR7 RF System on a Chip (SoC) is offered as a powerful, highly flexible multi-protocol SoC ideally suited for ANT and Bluetooth® Smart ultra-low-power wireless applications. The nRF51422 features a 32-bit ARM® Cortex™ M0 CPU with 256kB/128kB flash + 32kB/16kB RAM. An embedded 2.4GHz transceiver supports both Bluetooth Smart and the Nordic Gazell protocol stacks. The nRF51422 requires a single power supply and gives the designer the option of using on-chip linear regulators with a supply range of 1.8-3.6V, a direct 1.8V mode, and a on-chip DC-DC buck converter with a supply range of 2.1-3.6V. The use of the DC-DC converter can be dynamically controlled during run time and enables nRF51822 to operate at radio peak currents below 10mA @ 3V supply (TX @ 0dBm & RX).
