MFi Accessory Digital Audio Bridge
CP2614 Data Short
The CP2614 MFi Accessory Digital Audio Bridge chip is designed
to enable rapid development of accessories for Apple® iOS devices.
CP2614 provides built-in support for the Apple Made for iPod/iPhone/iPad ("MFi") protocol and the Lightning™ connector. It provides turnkey features including Digital Audio
streaming and communication with iOS apps. No firmware development is required to
use CP2614 – all customization options are selected using a simple GUI configuration
tool. These configuration options are then programmed directly into flash memory included in the CP2614. By eliminating the need to write a ground-up MFi protocol stack, the
CP2614 greatly simplifies development of iOS accessories and shortens time to market.
