nRF51822 Bluetooth® low energy and 2.4GHz proprietary SoC
The nRF51822 is a powerful, highly flexible multi-protocol SoC ideally suited for Bluetooth® low energy and 2.4GHz ultra low-power wireless applications. The nRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU with 256kB flash + 16kB RAM. The embedded 2.4GHz transceiver supports Bluetooth low energy as well as 2.4GHz operation, where the 2.4GHz mode is on air compatible with the nRF24L series products from Nordic Semiconductor.
nRF51822 also incorporates a rich selection of analog and digital peripherals that can interact without CPU intervention through the Programmable Peripheral Interconnect (PPI) system. A flexible 31-pin GPIO mapping scheme allows I/O like 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.
nRF51822 supports the S110 Bluetooth low energy protocol stack as well as 2.4GHz protocol stacks, including Gazell, both available free of charge in the nRF518 Software Development Kit. nRF51822 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 a 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 nRF51822 to operate at radio peak currents below 10 mA @ 3V supply (TX @ 0 dBm & RX).
nRF51822 is available in 6x6mm 48-pin QFN packages and 3.5x3.8mm 64 ball wafer-level chip-scale packages (WLCSP).
nRF51822 is available in either 256k or 128kB Flash size variants
