The KX1400 Development Kit provides the hardware and software necessary to quickly and easily interface the KX1400 Audio Playback IC to a PC-based host. The included KX1400 Evaluation Board simplifies the development of audio content and hardware prototyping for microcontroller-based designs.

The development kit software includes a complete Integrated Development Environment (IDE).  The IDE integrates all the necessary software tools for developing KX1400 audio files with an interface for in-system memory programming and the real-time execution of KX1400 commands and audio phrases from a PC-based host, eliminating the need for a microcontroller and firmware for initial evaluation and development.

The KX1400 Evaluation Board is populated with a KX1400EG (24-pin QFN), 16-MByte external flash memory for audio data storage, an MCU expansion header, and a 3.5mm (1/8" mini−plug) audio jack.
