Code density and execution On-chip DC/DC buck c onverter speed are considerably greater than for 8/16-bit platforms. The Individual po wer management for all peripherals Programmable Peripheral Interconnect (PPI) system provides Package options: 48-pin 6x6 QFN/WLCSP, Thin-CSP a 16-channel bus for direct and autonomous system peripheral communication without CPU intervention. This brings predictable APPLICATIONS latency times for peripheral to peripheral interaction and power saving benefits associated with leaving the CPU idle. The device Bluetooth low energy applications has 2 global power modes ON/OFF, but all system blocks and Wearables peripherals have individual power management control which Beacons allows for an automatic switching RUN/IDLE for system blocks Appcessories based only on those required/not required to achieve particular Computer peripherals tasks. CE remote controls for TV, STB and media systems Proximity and security alert tags The new radio forms the basis of the nRF51822s performance. Sports- and fitness sensors The radio supports Bluetooth low energy and is on air compatible Healthcare and lifestyle sensors with the nRF24L Series products from Nordic Semiconductor. Game controllers for computers Output power is now scalable from a maximum of +4dBm down Toys and Electronic games to -20dBm in 4dB steps. Sensitivity is increased at every level Domestic/Industrial control and data-acquisition and offers sensitivity ranges (dependent on data rate) from -96 to -85dBm, with -93dBm for Bluetooth low energy. Intelligent domestic appliances nRF51822 Product Brief Version 2.5 AHB Lite bus APB busEasy, fast and safe code development SPECIFICATIONS The nRF51822 offers developers a clean separation between Frequency band 2.4GHz ISM ( 2.40000 2.4835GHz) application code development and embedded protocol stacks. This means compile, link and run-time dependencies with the embedded On-air data rate 250 kbps, 1 Mbps or 2 Mbps stack and associated de-bugging challenges are removed. The Modulation GFSK Bluetooth low energy stack is a pre-compiled binary available from Nordic Semiconductor, leaving application code to be compiled Output power Programmable: +4 to -20dBm in 4dB steps stand-alone. The embedded stack interface uses an asynchronous Sensitivity -93dBm Bluetooth low energy and event-driven model removing the need for RTOS frameworks. -96dBm at 250kb -90dBm at 1Mbs OTA DFU -85dBm at 2Mbs The nRF51822 is supported by a Over The Air Device Firmware Radio current con- 16mA TX at +4dBM output power Upgrade (OTA-DFU) feature.
