Cypress Semiconductor Corp. (Nasdaq: CY) today announced that Griffin Technology has selected the PSoC® 3 programmable system-on-chip for four of its music-creation accessories. The StudioConnect, StudioConnect with Lightning, MIDIConnect, and GuitarConnect Pro each provide a digital audio interface that enables users to connect musical equipment to their iOS devices to create and edit music on the go. The PSoC 3 device manages the digital audio interface and handles Apple’s proprietary MFi (Made for iPod | iPhone | iPad) protocol to communicate with devices using Apple’s iOS operating system via both Apple’s 30-pin and new all-digital Lightning connectors.
Griffin’s StudioConnect combines digital audio and Musical Instrument Digital Interface (MIDI) capabilities to be used for recording and editing music on the iPad, and StudioConnect with Lightning adds compatibility with the new iPad (4th generation) and iPad mini. MIDIConnect provides industry standard MIDI input and output ports to an iOS device. GuitarConnect Pro connects guitars, violins or keyboards to an iPhone or iPad, enabling the user to record digital audio while practicing, composing or performing.
Cypress’s PSoC 3 MFi digital audio solution delivers bit-perfect audio streaming into and out of Apple’s GarageBand and other Core Audio and Core MIDI apps for Griffin’s accessories. With Cypress’s patent-pending USB audio clock synchronization and recovery scheme, PSoC 3 ensures no samples are dropped, delivering the highest quality digital audio with minimal external components at multiple audio sample rates (at standard intervals up to 24-bit audio, 48 KHz sampling rate). Cypress’s recently announced CY8CKIT-033A PSoC® 3 MFi Digital Audio Development Kit for Lightning supports the solution with license-free reference hardware, firmware, and iOS app software, providing the tools to quickly develop MFi digital audio accessories that are fully compatible with Apple’s all-digital Lightning connector.
“Griffin Technology was one of the first companies to create accessories for Apple’s mobile devices, and today we are a market leader in MFi accessories,” said Scott Naylor, Vice President of Product Development at Griffin Technology. “Our Nashville roots give us strong ties to the music industry, and PSoC delivers a best-in-class MFi digital audio solution that meets the audio-quality requirements of today’s musicians.”
