Powerful highly-flexible multi-protocol RF system on a chip
Nordic Semiconductor's nRF51422-QFAAR7 RF System on a Chip (SoC) is now
available from Mouser stock. The device is a powerful, highly-flexible
multi-protocol SoC ideally suited to ANT and Bluetooth Smart ultra-low-power
The nRF51422 features a 32-bit ARM Cortex M0 CPU with 256kB/128kB flash +
32kB/16kB RAM. An embedded 2.4 GHz 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 to
3.6V, a direct 1.8V mode and an on-chip DC-DC buck converter with a supply
range of 2.1 to 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 at 3V supply (TX at 0dBm and RX), says the company.
