For the availability of this product, please contact the sales office.
System Controller for Compact Disc Players
Description
The CXP1042Q is a 4-bit single chip microcomputer
based on the SPC500 series. It incorporates programs
in firmware for CD operations. It can be connected
directly to the CDL-500 series of LSIs for CD players,
and can directly drive LCDs, in addition to other features.
It can be employed in a wide range of equipment, from
deck-type CD players to radio cassettes and portable
systems.

INTRO
• LCDs can be driven directly. This includes time display, music calendar, remaining tunes and other display
functions.
• NEC format remote control input possible; direct tune selection through keypad and other functions can be
added.
• Supports auxiliary functions including synchronization input and double-speed playback.
• Easy switching between deck and portable equipment using external pins.
(i) With deck type selected, performs tray loading function.
(ii) With portable type selected, displays detection of weak battery and executes emergency termination
when battery voltage is low.
In this way, it functions specific to the system required.
• An simple tracking gain/balance function is built-in, enabling adjustment of the tracking gain/balance
according to the disc.

The tray switch is determined according to the state where Pin 2 (PY1/MODE) and Pin 16 (PC3/KI3) is
connected immediately after reset or not.
Connected: DSP expansion port used
Not connected: Microcomputer port used
However, use the microcomputer port when the OPEN/Batt-E function is employed for portable mode.
The selected mute (Pin 2 (PY1/MODE) or Pin 15 (PC2/KI2)) is used to identify which of the CXD2507A or
CXD2508A is employed for DSP.
Therefore, select the suitable method for the used DSP.
CXD2508A: DAC mute selected
CXD2507A: DSP mute selected

Combination mode is set when Pin 2 (MODE) and Pin 13 (KI0) is not connected with diode.
In this time, combines the function.
2. REP key combination mode
Combination mode is set when Pin 2 (MODE) and Pin 14 (KI1) is not connected with diode.
In this time, REP combines SHL and PRG functions.

List of Functions
1. Deck/Portable select Switches between deck mode and portable mode. In deck mode the tray
loading function is activated; in portable mode, the battery detection
function is activated.
2. Remote control input Accepts signals from a NEC format remote control unit. A 16-bit custom
code can be selected.
3. Keys to initiate playing can be selected.
4. Performs tune selection.
5. Performs fast-forward and rewind. The speed differs during Play and Pause.
, , ,
,
,
6. Remain Can display Single Remain, All Remain, Program Remain.
7. Repeat For repetition of one or of all tunes.
8. A←→B For performance of A←→B repeat.
9. Shuffle Performed shuffled (random) playing.
10. AUTO Inserts 4-second blanks between tunes.
11. INTRO Plays the initial 10 seconds of a disc.

CXP1042Q
1. Deck mode/portable mode selection
A feature of the CXP1042Q is its ability to be used in both deck-type and in portable equipment.
(a) Selection
Selection is executed through Pin 20 (LOAD/DECK-PT). Mode selection is determined by the condition of
this pin immediately after reset of the CXP1042Q.
When Pin 20 (LOAD/DECK-PT) is high: Deck mode
When Pin 20 (LOAD/DECK-PT) is low: Portable/radio cassette mode
(b) Deck mode
• In deck mode the tray loading function is activated.
• Pins necessary for tray operation:
For the loading motor
For the tray SW
Tray
Pin 19 (UNLOAD/Batt-W)
goes "H" when tray is ejected

The tray switch state is input from the microcomputer port or DSP port according to the microcomputer

(c) Portable mode
• In portable mode, when the lid is closed the operation changes to TOC reading.
• Pin 20 (LOAD/DECK-PT) should be held "L".
• Pin 11 (Disc IN/OPEN) should be connected to a switch that makes the pin go "L" when the lid is closed.
• Two pins used in deck mode can be employed to detect a reduced battery voltage.
• When Pin 19 (UNLOAD/Batt-W) is made "L" through the reduced voltage detection circuit, BATT is
displayed.
• In addition, when Pin 19 (UNLOAD/Batt-W) is "L", forcing Pin 12 (Disc OUT/Batt-E) "L" induces the STOP
state.
• Input the Disc IN/OPEN and Disc OUT/Batt-E to the microcomputer port because the DSP expansion port
can not be used for the portable mode.
(d) Selection of tray switch input port
The microcomputer port or DSP port can be selected for the tray switch input (Disc IN/OUT) according to the
state where Pin 2 (MODE) and Pin 16 (KI3) is connected immediately after reset or not.
Not connected: Microcomputer port used
Connected with diode: DSP port used
However, use the microcomputer port when the OPEN/Batt-E function is employed for portable mode.

In this example, the microcomputer port and DSP mute (CXD2507A) is used for the tray switch, and the REP key is
used as repeat key and / key is used in the combination mode.
• Tray switch selection
Connected: Input the content of tray switch from the DSP expansion port
Not connected: Input the content of tray switch from the microcomputer port

3. Mute function
The CXP1042Q has two mute pins, Pin 17 (MUTG...active high) and Pin 18 (MUT2...active low).
The command transferred to the DSP and the state of mute pin differ depending on the selected mute method
when mute is turned on.
• DAC mute (CXD2508A used)
When "mute on" is requested, set Pin 18 (MUT2) active and then transfer the attenuate command (A00000h)
to the DAC.
Only when "open/stop" is requested, set Pin 17 (MUTG) active after approximately 32ms from the command
transfer.
• DSP mute (CXD2507A used)
When "mute on" is requested, set Pin 17 (MUTG) and Pin 18 (MUT2) active and then transfer the mute
command (A207F0h) to the DSP.
Note that A007F0h is transferred when mute is turned off both for DAC mute and DSP mute.
