T8xC51SND1

Rev. D – 15-Nov-01

Additional features are supported by the T8xC51SND1 MP3 decoder such as volume,

bass, medium, and treble controls, bass boost effect and ancillary data extraction.

9.6 Audio Output Interface

The T8xC51SND1 implements an audio output interface allowing the decoded audio bit-

stream to be output in various formats. It is compatible with right and left justification

PCM and I2S formats and thanks to the on-chip PLL (see Section 9.1) allows connection

of almost all of the commercial audio DAC families available on the market.

9.7 Universal Serial Bus Interface

The T8xC51SND1 implements a full speed Universal Serial Bus Interface. It can be

used for the following purposes:

•

Download of MP3 encoded audio files by supporting the USB mass storage class.

•

In System Programming by supporting the USB firmware upgrade class.

9.8 MultiMediaCard Interface

The T8xC51SND1 implements a MultiMediaCard (MMC) interface compliant to the V2.2

specification in MultiMediaCard Mode. The MMC allows storage of MP3 encoded audio

files in removable flash memory cards that can be easily plugged or removed from the

application. It can also be used for In System Programming.

9.9 IDE/ATAPI interface

The T8xC51SND1 provides an IDE/ATAPI interface allowing connexion of devices such

as CD-ROM reader, CompactFlash cards, Hard Disk Drive… It consists in a 16-bit bidi-

rectional bus part of the low-level ANSI ATA/ATAPI specification. It is provided for mass

storage interface but could be used for In System Programming using CD-ROM.

9.10 Serial I/O Interface

The T8xC51SND1 implements a serial port with its own baud rate generator providing

one single synchronous communication mode and three full-duplex Universal Asynchro-

nous Receiver Transmitter (UART) communication modes. It is provided for the

following purposes:

•

In System Programming.

•

Remote control of the T8xC51SND1 by a host.

9.11 Serial Peripheral Interface

The T8xC51SND1 implements a Serial Peripheral Interface (SPI) supporting master

and slave modes. It is provided for the following purposes:

•

Interfacing DataFlash memory for MP3 encoded audio files storage.

•

Remote control of the T8xC51SND1 by a host.

•

In System Programming.
