Cypress Semiconductor announced the availability of a new development kit that speeds design of digital audio accessories for iPhone, iPad and iPod (iP…). The CY8CKIT-033A PSoC 3 MFi Digital Audio Development Kit for Lightning includes license-free reference hardware, firmware, and iOS app software, providing the tools to develop MFi (Made For iP…) digital audio accessories that are fully compatible with Apple’s all-digital Lightning connector, which is used in for instance the iPhone 5 and the iPad mini.


The reference design connects PSoC 3 to iP…. Compatible with both Apple’s Lightning and 30-pin dock connectors and with Cypress’s USB audio clock synchronization and recovery scheme, PSoC 3 ensures bit-perfect audio with minimal external components at multiple sample rates (at standard intervals up to 24-bit audio, 48-kHz or 96-kHz sampling rate). The kit works with any Core Audio or Core MIDI iOS app, including GarageBand and music streaming apps like Pandora and Spotify. An example iOS app enabling bidirectional communication between apps and accessories is included.
