CP2614 MFi Accessory Digital Audio Bridge

Note: The CP2614 is not recommended for new designs.

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.
