Dsp/mcu System For Cd-da, Cd-ca, Cd-rom Player

The STA1052 is a single chip device which performs all functions related to read back of optical disk: servo control operations, reading optical disc decoding the High frequency signals, EFM decoding, error correction, software decoding of MP3 and WMA encoded Audio sample rate conversion, managing file system, serial transfer of Audio program through I 2S/SPDIF, direct playback of Audio through in-built Audio DAC It also performs software decoding of MP3, AAC and WMA encoded Audio from USB or SD card memory supports. Commands CAN be exchanged with the Host MCU either via one I 2C port or two SPI ports. STA1052 chip comes along a broad software suite that comprehends different types of compressed Audio files, File System Management, Play Lists. By STMicroelectronics
