STA016A
2 DESCRIPTION
The STA016A is a single chip MPEG 1, 2 and 2.5 Layer III audio decoder with embedded CDROM decoding
capability. It can be easily connected to most existing CDDSP devices via a software configurable serial link. A
tipical application block diagram is show in Figure 1. The audio sources, for instance could be an external flash
memory.
A useful bypass mode allow using this device also as an audio processor for volume and tone controls.

3 OVERVIEW
The device can decode/process data coming from three possible sources, as showed in Figure 2:
■ CDDSP serial link: using this input interface, besides MP3 encoded data CD, it's possible to playback
also standard Audio CD using the available volume and tone equalizer features of the device and
allowing the use of only one D/A converter with no external analog switch.
■ SDI input interface: through this input interface it's possible to decode any MP3 bitstream coming, for
instance, from an external flash memory.
2
■ I S input interface: this interface can be used to process an external audio source (tuner, for instance)
through the DSP based volume and tone controls:this BYPASS mode can avoid the use of additional
D/A converters or postprocessing units.
3.1 MP3 decoder engine
The MP3 decoder engine is able to decode any Layer III compliant bitstream: MPEG1, MPEG2 and MPEG2.5
streams are supported.
Decoded audio data goes through a software volume control and a two-band equalizer blocks before feeding
2
the output I S interface. This results in no need for an external audio processor.

The basic functions of the device can be fully operated via the I C bus. Besides that the GPSO interface can be
used to move huge amount of data this fast and flexible interface can achieve transfer rates up to 5 Mbit/s.
The embedded DSP firmware implements all the layers required to decode a standard data CD, as shown in
the Figure 4:

ISO9660 File System Decoding
(with Joliet support)
Browsing Command Interface
The whole CDROM and file-system decoding task is performed by embedded firmware. The application MCU,
basically, must manage CDDSP device according to STA016A requests. Three basic command flows exist:
■ MCU -> STA016A: commands used to handle decoder operation and to ask for specific information like
2
filename, filelength, sector raw data, etc. This flow will use I C (GPSO for special operations) interface.
■ STA016A -> MCU: this channel is used to retrieve inquired information and to inform MCU that a
2
CDDSP specific operation must be performed (like pick-up repositioning). This flow is based on I C link
plus an additional interrupt signal in order to avoid time consuming polling techniques.
■ MCU -> CDDSP: the CDDSP management is fully up to the application MCU. This architecture allows
maximum flexibility and easy migration from existing CDPlayers to MP3 CDPlayers.

STA016A
5 HOST REGISTERS
The following table gives a description of STA016A register list.
2
The STA016A device includes 256 I C registers. In this document, only the user-oriented registers are de-
scribed. The undocumented registers are reserved or unused. These registers must never be accessed (in
Read or in Write mode). The Read-Only registers must never be written
We can split the data flux in different time periods (see following diagram) meanwhile host registers can be read
or written :
■ DWT : During Whole Time (at any time during process).
■ DEC : During External Config (period between RUN=2 and RUN=1).
■ DBO : During Boot (period between RUN=0 and RUN=2).
■ ABO : After BOot (period after RUN=1).
■ AEC : After External Config (period after RUN=2).
■ EDF : Every Decoded Frame (each time a frame has been decoded).
■ EDB : Every Decoded Block (each time a block has been decoded).

Description :
– When a software reset occurs, register RUN
is reset (value 0) by the dsp (see I).
Description :
– When boot routines are finished, the dsp
write inside RUN register the value 2 : this is
the start of the external configuration period
(start of DEC : see I).
– When the external device wants to end the
external configuration period, it must write the
value 1 inside the register RUN: this is the run
command that starts the decoding process
(see I).
For data flux using USSB Input, if SKIP == n>2, de-
coder skip (n-1) out of n frames. Note that maximum
value for n is 8, and if n==0 or n==1, no frames is
skipped.

8 COMMAND PROTOCOL CONFIGURATION
General Information About The Command Protocol
I2C protocol :
CD_module & mmdsp are using an I2C protocol to communicate : CD_module is master of the I2C protocol,
and can access (in read and write mode) host registers of the STA016A to write commands to the mmdsp and
to read request from the mmdsp. It must use following I2C syntax :
device_address, host_register_number, host_register_value
where :
for a write acces, device_address is 0x86.
for a read acces, device_address is 0x87.
Writing a command to mmdsp :
CD_module write its command inside dedicated host registers (mainly H64 to H69), then it must signals the writ-
ing of this command to mmdsp by sending the interrupt IT_CMD to the core of mmdsp.
Note that IT_CMD is generated by cd_module threw a falling edge on the input line number 0 of the STA016A
38/43
STA016A
(the INTLINE[0] pin).
8.0.1 Reading a request from mmdsp :
MMDSP write its request inside dedicated host registers (mainly H70 to H78 and H134 to H169), then it signals
to cd_module that it must read a request by sending the interrupt IT_REQ.
Note that IT_REQ interrupt is generated by mmdsp on the IRQB pin of STA016A.
Note also that once it has finished to read the message, cd_module must always acknowledge it by reading
H10.
