    GENERAL DESCRIPTION

    Based on the market leading nRF24XX RF core, the nRF24AP1 combines the best of 2 worlds, and integrates a unique ultra-low power 2.4GHz transceiver for wireless communication with Dynastream Innovation' s production-proven low power network protocol, ANT, to create a true single chip solution. The nRF24AP1 is the ultimate solution for customers who are looking for a simple to use 2.4GHz transceiver for global operation, but do not want to spend months and years on integrating a networking standard protocol into their system. The nRF24AP1 is a drop-in wireless communications solution that provides private
    and public network connectivity and eliminates the need to purchase third party protocol stacks and acquire standards certification through expensive acceptance testing. The nRF24AP1 is the solution of choice for those customers
    whose main interest is offering the longest battery lifetime, lowest cost, and smallest size for their products.

    The new component from Nordic Semiconductor ASA, is manufactured in a modern 0.18µm process, and includes a multitude of features to make your product the lowest power, first-to-market and certainly the lowest cost system
    around. The ANT protocol is used in coin cell battery operated watches for heart rate monitoring, and other sports instruments, but is equally well suited for industrial as well as medical applications.

    The entire radio, protocol, peripherals, inductors and filters, are integrated in a single chip that gives the lowest cost solution to the end user. The only external components needed to make a complete system are a crystal, some RC components, and a low cost MCU controlling the application. The application MCU is interfaced to the nRF24AP1 via a UART, or SPI serial port. The total solution fits into a 5x5mm QFN package.

    Using the worldwide 2.4GHz frequency band the nRF24AP1 eliminates the need for several hardware platforms to cover a global market, easing logistics and ensuring portability for the end customer.
