New Products | July 17, 2011

Microchip has developed a PIC32-based development kit targeting high-quality audio applications such as home entertainment systems, automotive sound systems and portable audio players. Described as a complete platform that doesn't break the budget for high quality audio, it can also interface for Microchip's development platform of the iPod and iPhone.

The Audio Development Board for PIC32 MCUs features a 24bit Wolfson audio codec, a two-inch color LCD Display, a USB interface, and an onboard microphone. Supported by Microchip’s free software libraries, the company claims the kit provides a perfect solution for the development of speech and audio recording and playback products.

The 80-MIPS PIC32MX795F512L MCU on the audio development board features 512kbyte Flash and 128kbyte RAM, providing plenty of processing power and memory to decode, analyze and play back audio and speech.

Libraries are available for speech recording and playback, as well as MP3 music decoding applications. Additionally, an audio Sample Rate Conversion (SRC) library for 33kHz, 44.1kHz and 48kHz is also supported, which enables developers to reduce component costs for playback solutions.

There are also libraries available for managing the USB interface and driving the on-board color LCD display, which features 16-bit color images. For those developers who are enrolled in the Apple Made For iPod (MFi) Licensing Program, the kit also interfaces to Microchip’s accessory development platform for iPod and iPhone.
