Microchips compact MP3 algorithm designed to fit in small memory footprint PIC32MX Microcontrollers. This code requires only 28MIPS of performance (CD Quality audio), 42KB Flash and 11KB RAM memory for operation on the PIC32MX. Microchip offers MP3 Decoder library both in non-modifiable binary code and source code formats that enables usage on high performance PIC32MX devices. This part number is for Non-modifiable binary code. Source code is also available on Microchip Direct. Requires patent-only licensing through technicolor.
