Nordic Semiconductor nRF51422_xxAA

The Nordic Semiconductor nRF51422_xxAA is a The nRF51422_xxAA is a powerful, highly flexible multi-protocol SoC ideally suited for ANT+ and 2.4GHz ultra low-power wireless applications. The nRF51422_xxAA is built around a 32-bit ARM® Cortex™ M0 CPU with 256KB flash + 16KB RAM. The embedded 2.4GHz transceiver supports ANT as well as proprietary 2.4GHz operation, where the nRF51422_xxAA is on-air-compatible with the nRF24L and nRF24AP series products from Nordic Semiconductor. nRF51422_xxAA also incorporates a rich selection of analog and digital peripherals that can interact without CPU intervention through the Programmable Peripheral Interface (PPI) system. A flexible 31-pin GPIO mapping scheme allows I/O such as serial interfaces, PWM and quadrature demodulator to be mapped to any device pin as dictated by PCB requirements. This enables complete design flexibility associated with pin-out location and function. nRF51422_xxAA supports an embedded S210 ANT protocol stack from Dynastream Innovations as well as 2.4GHz protocol stacks, including Gazell, both available free of charge in the nRF5 Software Development Kit. nRF51422_xxAA requires a single power supply and gives the user the option of using on chip linear regulators giving a supply range of 1.8-3.6V, a direct 1.8V mode and an on-chip DCDC buck converter giving a supply range of 2.1-3.6V. The use of the DC-DC converter can be dynamically controlled during run time and enables nRF51422_xxAA to operate at radio peak currents below 10mA @ 3V supply (TX @ 0dBm & RX). This device requires additional software from Nordic Semiconductor to be supported in Keil MDK. Please contact Nordic Semiconductor to obtain the nRF51 SDK.
