吊装工具STA1052Description 1 Description 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 I2S/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 I2C 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.
The key Media and File T ypes supported are briefly reported below:
●Ability to play any USB/SD card compatible solid state memory media
●MPEG1-Layer 2 compressed audio files
●Playback of MP3 compressed audio files (all bit rates and VBR)
●Playback of lower bit rate MPEG2 layer 3 files and MPEG-2.5 extension
●Playback of WMA version 9 compressed audio files
●Playback of iTunes AAC compressed audio files
●Sample rate converter for recorded sampling rates other than 44.1kHz
●Support FAT16/FAT32 file systems
●Support ISO9660 and Joliet file systems
The software can manage the following File Information: folder and file names.
ID3 tag information - as per versions 1.0-1.1, 2.0 - 2.4- is reported. Further parameters
made available by ST software are: File type (i.e. .mp3, .wav, .wma, .cda, .aac), Bit rate,
entire file path for current track and track elapsed time.
STA1052 software provides the essential Navigation Commands: Previous/Next , Fast
forward/Rewind, Jump to any file, Scan, Pause. All these commands can be programmed
and configured via Command Protocol Interface.
Two different types of Playlists are supported: Playlists with .pls extension, Playlists with
.
m3u extension.
Robust software architecture provides an efficient error handling and related messaging.
ST developed a software architecture that allows the patching of a few parts of software
resident in ROM. Software patches are loaded into a very inexpensive serial Flash which
provides the capability to patch up to 40 KByte of ROM software.
Software build (patching) upgrade from media USB and SD card and from host MCU onto
serial Flash is supported.
STA1052 is intended for use in automotive entertainment system.
