Microchip Human Interface Solutions

Audio provides a means of communication, improves 

ease of use and delivers entertainment. It can transform 

the mood of an environment, help us escape a noisy 

commute, assist us in machine interface or improve the 

quality of life for the visually impaired. Bringing audio to 

your application enhances its ability to meet the needs 

of your customers. Bringing your product to market with 

the right mix of performance and price in the timeliest 

manner is important to your business. Microchip provides 

microcontrollers, development platforms and free software 

source code to help you bring a cost effective design to 

market in the shortest time possible.

Most 8/16/32-bit PIC microcontrollers can generate 

tones, alarms and musical notes in various applications. 

The dsPIC DSCs and PIC32 MCUs have DSP libraries 

included in their respective compilers to enable higher 

performance and more efficient processing of high quality 

audio. Many devices now offer I

2

S/SPI modules for more 

convenient CODEC interface. The PIC32MX1/MX2 Series 

of MCU’s offer CODEC master clock support with very 

fine control for reduced CODEC cost and audio buffer 

management.
