Audio mixer development boards

28 November 2012 Design Automation

Microchip has developed two new digital audio mixer boards based on low pin-count 32-bit PIC32 microcontrollers (MCUs).

The DM320014 USB digital audio accessory board uses standard USB 2.0 Mini-B connectivity, whilst the DM320413 digital audio mixer board offers Apple portable device connectivity.

The two development boards, each powered by a Microchip PIC32MX250F128 32-bit MCU, enable audio and voice device development for a broad range of applications. Both are designed for easy integration of digital and analog audio into the target application.

Key features include interfaces for digital audio via USB Mini-B or the Apple iOS interface; line-in and microphone-in for convenient connectivity to analog audio sources, such as microphones or instrument pickups; and line-out and headphone-out for line-level output and headphone connectivity.

Each board provides an excellent starting point for a portable music player dock design. Additionally, their features allow the mixing of digital and analog audio, using the PIC32’s processing capabilities.

The development boards are suitable for applications in the consumer and automotive markets, such as consumer audio docks, including those in stereo systems; noise-cancelling headsets; clock radios; or A/V entertainment system sounds bars; as well as in automotive vehicles that offer portable music player docking capabilities.

To lower the cost of designs that need to decode MP3 files, Microchip is also releasing a Compact MP3 Decode Library. This new code requires only 21 KB of RAM and can run on the PIC32MX250F128.

The boards support immediate development using Microchip’s MPLAB X Integrated Development Environment, and can be programmed and debugged with the PICkit3.
