Code density and execution Flexible power management for all peripherals speed are considerably greater than for 8/16-bit platforms. The Programmable Peripheral Interconnect (PPI) system On-chip DC-DC converter provides a 16-channel bus for direct and autonomous system Package options: 48-pin 6x6 QFN, 64-ball WLCSP peripheral communication without CPU intervention. This APPLICATIONS brings predictable latency times for peripheral to peripheral interaction and associated power saving benefits associated Bluetooth low energy applications with leaving the CPU idle. The device has 2 global power modes Wearables ON/OFF, but all system blocks and peripherals have individual Beacons power management control which allows for an automatic Appcessories switching RUN/IDLE for system blocks based only on those Smart Home required/not required to achieve particular tasks. ANT/ANT+ Sensor networks Wearable sensors The new radio forms the basis of the nRF51422s performance. Computer peripherals The radio supports Bluetooth Smart and ANT and is on-air CE remote controls for TV, STB and media systems compatible with nRF24AP- and nRF24L Series products from Proximity and security alert tags Nordic Semiconductor. Output power is now scalable from Sports and fitness sensors a maximum of +4dBm down to -20dBm in 4dB steps with a Healthcare and lifestyle sensors -36dBm whisper mode. Sensitivity is increased at every level and offers sensitivity ranges (dependent on data rate) from Game controllers and computers -96dBm to -85dBm, with -93dBm for Bluetooth Smart, and Toys and electronic games -90dBm for ANT.
