NRF51822-QFAB-R7 IC RF TXRX BLE 48QFN

The nRF51822 uses the 32-bit ARM Cortex M0 MCU, together withextensive flash availability, 256kB/128kB in total with 40kB-180kBavailable for application development. Code density and executionspeed are considerably greater than for 8/16-bit platforms. TheProgrammable Peripheral Interconnect (PPI) system providesa 16-channel bus for direct and autonomous system peripheralcommunication without CPU intervention. This brings predictablelatency times for peripheral to peripheral interaction and powersaving benefits associated with leaving the CPU idle. The devicehas 2 global power modes ON/OFF, but all system blocks andperipherals have individual power management control whichallows for an automatic switching RUN/IDLE for system blocksbased only on those required/not required to achieve particulartasks.The new radio forms the basis of the nRF51822's performance.The radio supports Bluetooth low energy and is on air compatiblewith the nRF24L Series products from Nordic Semiconductor.Output power is now scalable from a maximum of +4dBm downto -20dBm in 4dB steps. Sensitivity is increased at every leveland offers sensitivity ranges (dependent on data rate) from -96 to-85dBm, with -93dBm for Bluetooth low energy
