Cypress Semiconductor Corp. (Nasdaq: CY) today announced that TASCAM, the professional audio division of TEAC Corporation, has selected the
programmable system-on-chip for its new iM2, iM2X, and iXJ2 microphones. The pocket-sized stereo microphone accessories each turn the iPhone, iPad, and iPod touch into audio recorders that deliver bit-perfect streaming with no added or dropped audio samples. The products rely on the PSoC 3 device to seamlessly manage the digital audio interface and handle Apple’s proprietary MFi (Made for iPod, iPhone, and iPad) protocol to communicate with devices using Apple’s iOS operating system.
The iM2, iM2X, and iXJ2 plug into Apple’s dock connector for iOS devices. The iM2 and iM2X each feature a pair of condenser microphones that are adjustable over 180 degrees for optimal sound capture, and they each contain a preamp that can handle up to 125 decibels for the loudest concerts and instruments. The iXJ2 provides two microphone or line inputs that can be used individually or in tandem for stereo recordings, making it ideal for video capture. Each accessory is powered by the connected iOS device and works with TASCAM’s PCM Recorder iOS app, Apple’s GarageBand, and other Core Audio compatible recording apps.
Cypress’s PSoC 3
MFi digital audio solution
manages the interface between the TASCAM accessories and any iOS device via Apple’s dock connector. The designs leverage PSoC 3 to provide pristine audio recording, as well as simultaneous playback. With Cypress’s patent-pending 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).

“With PSoC 3’s flexible architecture and drag-and-drop MFi compatibility, we developed the iM2, iM2X, and iXJ2 to put high-quality audio recording capabilities into the hands of iPhone and iPad users,” said Shinya Yoshino, Executive Officer of Research and Development at TEAC. “The PSoC 3 MFi digital audio solution provides TEAC with an excellent springboard, enabling rapid time-to-market and a solid foundation for a broad family of music accessory products.”
