Nordic Semiconductor nRF51822 Bluetooth low energy and 2.4GHz wireless SoC Nordic Semiconductor nRF51822 with 2.4GHz Bluetooth low energy wireless SoC provides a multi-protocol SoC for Bluetooth low energy and 2.4GHz ultra-low power wireless applications. Nordic Semiconductor nRF51822 Bluetooth low energy and 2.4GHz wireless SoC with a 32 of ARM®Cortex ™ M0 CPU with 256KB Flash and 16KB RAM. Embedded 2.4GHz Transceiver 2.4GHz Bluetooth low power consumption and operation, which in the 2.4GHz model is compatible with the air nRF24L products from Nordic Semiconductor. A wide variety of analog and digital peripherals can not interact through a programmable peripheral interface (PPI) system CPU intervention. Flexible 31-pin GPIO mapping scheme allows I / O like serial interface, PWM, and quadrature demodulator mapped to any device pin requirements determined by the PCB. This makes the position of the pin and functionally related complete design flexibility. It supports S110 Bluetooth low energy protocol stack and 2.4GHz protocol stacks, including Gazell, either free of charge nRF518 Software Development Kit. NRF51822 require a single power supply, provides users with an on-chip linear regulator provides power range of 1.8-3.6V, direct mode and on-chip 1.8V - buck converter in the power range gives options of 2.1-3.6V.     Feature 2.4GHz multi-protocol radio 32-bit ARM Cortex M0 Processor 256kB Flash / RAM 16kB of Software stack can be downloaded as Pin-compatible with other devices nRF51xxx Independent of the protocol stack Application Development Comprehensive series on the air nRF24L compatible Programmable output power to + 4dBm -20dBm RSSI Use the FIFO memory mapping EasyDMA Dynamic air load length of up to 256 bytes Flexible, configurable 31 GPIO pins Programmable Peripheral Interface - PPI Simple ON / OFF global power mode Complete digital interfaces include : SPI / 2 wire / UART 10 ADC 128 AES ECB / CCM / AAR coprocessor Quadrature demodulator Cost external 16MHz crystal oscillator of ± 40ppm Low-power 16MHz crystal and RC oscillator Ultra-low power 32kHz crystal and RC oscillator Wide supply voltage range (1.8V to 3.6V) The on-chip / buck converter Single power management all peripherals Package options : 48-pin QFN 6 × 6 Application Bluetooth Intelligent Application Phone Accessories Computer Peripherals For television, set-top boxes and media systems CE remote control Proximity and safety warning labels Sports- and fitness sensors Health and lifestyle sensor Computer game controllers Toys and video games Domestic / industrial control and data acquisition Smart RFID tags to track and social interaction Audience response system Smart Appliances
