The nRF51422 is a powerful, flexible multi-protocol SoC ideal for ANT+ and 2.4GHz ultra-low power wireless applications. The nRF51422 is built on a 32-bit ARM® CortexTM M0 CPU with 256KB flash + 16KB RAM. The embedded 2.4GHz transceiver supports ANT and patented 2.4GHz operation, where the nRF51422 is wirelessly compatible with Nordic Semiconductor's nRF24L and nRF24AP families.
The nRF51422 also features a rich set of analog and digital peripherals that can interact through a Programmable Peripheral Product Interconnect (PPI) system without CPU involvement. The flexible 31-pin GPIO mapping scheme allows I/O (such as serial interface, PWM, and sinusoidal demodulator) to be mapped to any device pin based on PCB demand indication. This enables complete design flexibility and pin location and functionality.
The nRF51422 supports Dynastream InnovaTIons' embedded S210 ANT protocol stack and 2.4GHz protocol stack (including Gazell), both of which are available free of charge in the nRF514 software development kit. The nRF51422 requires separate power supply. If the power supply range is between 1.8-3.6V, the user can choose to use the on-chip linear rectifier. If the power supply range is between 2.1-3.6V, the DC 1.8V mode and the DCDC transformer on the chip can be selected. The use of a DC-DC transformer can be dynamically controlled during operation and the RF peak current during operation of the nRF51422 is less than 10 mA @ 3V supply (TX @ 0 dBm & RX).
The nRF51422 is available in a 48-pin 6x6 QFN package and a 3.5x3.8mm 64-ball wafer level chip scale package (WLCSP).
