ZVMP1xx is based on ZARAM¡¯s high performance 16-bit DSP core optimized for audio signal processing, so the chip is an ideal solution for MP3 players.
ZVMP1xx¡¯s highly integrated features and high power efficiency enable system makers to develop cost-effective solution with a long battery life.
ZVMP1xx supports multiple audio decompression algorithm-MP3, WMA, OGG, and also provides voice recording functions using ADPCM and ZARAM¡¯s own specific low bit rate voice compression algorithm, ZCELP.
ZVMP1xx also introduces sound effect algorithm, LEF, for audio quality enhancement, which algorithm is DEDEKIND R&D¡¯s patent technology certified in seven countries.
ZVMP1xx supports USB2.0/1.1 device, various memory interfaces, an interface to color LCD, and FM tuner interface and control.
