The world's leading supplier of integrated microcontrollers, analog devices and flash memory solutions - Microchip Technology Inc. (Microchip Technology, USA) announced the launch of two new digital audio mixer boards based on low pin count 32-bit PIC32 microcontrollers (MCUs). The DM320014 is a USB digital audio accessory board that uses a standard USB 2.0 Mini-B connection. The DM320413 is a digital audio mixer board that provides Apple portable device connectivity. Both development boards use Microchip's PIC32MX250F128 32-bit MCU to enable the development of audio and voice equipment for a wide range of applications.
The two boards are designed to easily integrate digital and analog audio into target applications. Its main features include a digital audio interface via the USB Mini-B or Apple iOS interface, line input and microphone input for easy connection to analog audio sources such as microphones or musical instrument pickups, as well as line output and headphone connected line outputs and headphones Output. Both of these development boards provide a great starting point for portable music player base designs. In addition, these features take advantage of PIC32's advanced processing capabilities to enable digital and analog audio mixing. Two development boards for consumer electronics and automotive market applications such as consumer audio docks (including stereo systems), noise canceling headphones, clock radios or A/V entertainment system bar audio, and portable music players in cars Docking base.
These two new development boards demonstrate Microchip's commitment to digital audio development with PIC32 MX1 and MX2 microcontrollers. These devices have 66 DMIPS performance, up to 128 KB of flash memory, 32 KB of RAM, USB, I2S interfaces, and an advanced clocking scheme. This scheme provides an external codec (CODEC) with the desired signal, eliminating the need for a codec with a built-in PLL. In addition, this series of MCU also provides an 8-bit parallel master port (perfect LCD interface), support for Microchip's mTouch capacitive touch technology and many other common features.
To maximize the cost-effectiveness of designs that need to decode MP3 files, Microchip also released a compact MP3 decoding library. This new code library only requires 21 KB of RAM and can run on the PIC32MX250F128. With these new development boards and available compact MP3 decoding libraries, designers can reduce development time and speed time to market.
Sumit Mitra, vice president of Microchip's MCU32 division, said: “We have already seen the traction power of the PIC32 in audio applications. Following the release of Microchip’s PIC32MX1 and MX2 series with the I2S CODEC interface in February, market demand has really emerged. The new digital audio board helps developers easily benefit from the audio capabilities of the PIC32."
Development support developers can now begin designing with Microchip's MPLAB X integrated development environment and these new development boards. Both boards can be programmed and debugged with the separately purchased PICkit 3 (part number PG164130).
Both the packaging and supply development boards are available. The DM320413 is only available to Apple MFi licensors through an Apple Authorized Reseller. DM320014 can be purchased at microchipDIRECT. Microchip's compact MP3 decoding library will be available on September 28 in microchip DIRECT in an unmodifiable binary form (part number SW320012-1) or modifiable source code (part number SW320012 2).
