A 32-bit microcontroller (MCU)-based development kit for the creation of high-quality, 24-bit audio applications features an 80 MIPS PIC32 MCU, a 24-bit Wolfson audio codec, a two-inch color LCD Display, a USB interface and an onboard microphone. Supported by free software libraries, the Audio Development Board for PIC32 MCUs from Microchip Technology provides a solution for the development of speech and audio recording and playback products. Target applications include docks for portable audio players, home-entertainment systems and automotive sound systems.  

The 80-MIPS PIC32MX795F512L MCU on the audio development board features 512 Kbyte flash and 128 Kbyte RAM, providing plenty of processing power and memory to decode, analyze and playback 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 33 kHz, 44.1 kHz and 48 kHz is also supported. This enables developers to reduce component costs for playback solutions. There are also libraries available for managing the USB interface and driving the onboard 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. The Audio Development Board for PIC32 MCUs is available today for $149.99
