CXP1021Q
System Controller for Compact Disc Players For the availability of this product, please contact the sales office.
Description The CXP1021Q 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-40 series of LSIs for CD players, and can directly drive LCDs, in addition to other features. It also supports the pitch control function and can be employed in a wide range of equipment, from deck-type CD players to radio cassettes and portable systems. 80 pin QFP (Plastic)

Multiple functions can be combined.
* LCDs can be driven directly. This includes time display, music calendar, remaining tunes and other display functions. * NEC format remote control input possible; index serch, direct tune selection through keypad and other functions can be added. * Supports auxiliary functions including synchronization input, double-speed output and pitch control. * 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. * A built-in test mode facilitates adjustment of the CD player and can be used for tests and evaluations.

List of Functions 1. 2. TEST MODE Deck/Portable select For adjustment of the CD player. 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. Accepts signals from a NEC format remote control unit. A 16-bit custom code can be selected. Keys to initiate playing can be selected. Performs tune selection. Performs fast-forward and rewind. The speed differs during Play and Pause. Can display Single Remain, All Remain, Program Remain. For repetition of one or of all tunes. For performance of A B repeat. Performed shuffled (random) playing. Inserts 4-second blanks between tunes. Plays the initial 10 seconds of a disc. Enables programming of up to 21 tunes. Enables direct tune selection using the keypad (for use with a remote control unit only). A function for detection of reduced battery voltage is provided by the BattW and Batt-E pins (portable mode only). For sync rate input and activation. Double-speed playback is possible by attaching an external circuit. With the deck mode selected, tray loading is possible. The tune select and fast-forward keys can be combined or kept independent, and the repeat key and mode key can be selected. Performs index search (for use with a remote control unit only). Accelerates/decelerates the pitch (playing speed) to vary the internal. -9-

1. Deck mode/portable mode selection A feature of the CXP1021Q is its ability to be used in both deck-type and in portable equipment. (a) Selection Selection is executed through Pin 39 (LOAD/DECK-PT). Mode selection is determined by the condition of this pin immediately after reset of the CXP1021Q. When Pin 39 (LOAD/DECK-PT) is high: Deck mode When Pin 39 (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 Pin 40 (UNLOAD/Batt-W) goes "L" when tray is ejected Pin 39 (LOAD/DECK PT) goes "L" when tray is closed For the tray SW Pin 37 (Disc IN) goes "L" when the tray is closed Pin 38 (Disc OUT/Batt-E) goes "L" when tray is fully opened
Tray
UNLOAD direction LOAD direction
* The relation between Pin 40 (UNLOAD/Batt-W) and Pin 39 (LOAD/DECK-PT) is as follows. State Open (stopped) LOAD direction UNLOAD direction Pin 40/UNLOAD H H L Pin 39/LOAD H L H
(c) Portable mode * In portable mode, when the lid is closed the operation changes to TOC reading. * Pin 39 (LOAD/DECK-PT) should be held "L". * Pin 37 (Disc IN) 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 40 (UNLOAD/Batt-W) is made "L" through the reduced voltage detection circuit, BATT is displayed. * In addition, when Pin 40 (UNLOAD/Batt-W) is "L", forcing Pin 38 (Disc OUT/Batt-E) "L" induces the STOP state.

2. Key combination selection This function can be used to reduce the number of keys needed. (a) Selection Selection is made through Pin 61 (KEYSEL). Selection is determined by the state of this pin immediately after reset of the CXP1021Q. When Pin 61 (KEYSEL) is high: keys are combined. / , / When Pin 61 (KEYSEL) is low: keys are independent. / , / (b) Operation when Pin 18 (KEYSEL) is high Key name Description Function differs depending on length of time pressed.

(Example: custom code "1234") By forming a diode matrix, a single bit of data is created; adding a diode at each point sets that point to "0". Please use the above example as a reference. This matrix is read only immediately after the power is turned on.
The data on the receiving end is as shown above and cannot be changed. For the transmitting end, please refer to the specifications of the transmitting side chip.

This function is used to play the CD player in synchronization with the record key of a cassette deck. Operation is triggered by (the falling edge), and differs depending on the state of the CD player. (a) While stopped The CD player enters the Play state, and starts after 4 seconds. During this time, playback is at double speed. (b) During play pause The CD player pauses at the beginning of the current tune, and after 4 seconds begins playing. (c) While open When the tray is loaded, the player enters the Play state. Output is not at double speed. (d) During shuffled play Play is shuffled, and (a) and (b) are executed. (e) During program play Program play begins, and (a) and (b) are executed. They are not executed if Pin 69 (SPD2) doesn't have a double speed circuit.

19. External control On/off control can be executed for a voice canceler. * Pin 70 (EXTCTL), the external control output, is switched between "H" and "L" every time pressing EXCTL . Note) The voice cancel circuit is not incorporated. An external circuit is required when this function is used.
Description of Operation 20. Test Mode Branching to Test mode is achieved by setting Pin 62 (TEST IN) to "L". When Pin 62 (TEST IN) is set "L" and Reset Start is executed, focus searching is repeated at the current pickup location. If a disc is loaded, the focus is turned on, the CLV-A and tracking sled servo are turned on, mute is turned off, and play is begun. In deck mode, the OPEN key can be used to operate the tray. When the tray closes, focus searching is begun. In portable/radio cassette mode, operation does not begin until the lid is closed. When the lid is closed, focus searching is begun. (a) Focus bias When reset is executed without a disc loaded, the lens is moved up and down in approximately one second intervals. (b) Running check When reset is executed with a disc loaded, focus searching, focus on, CLV-A, and tracking sled servo are set on, mute is turned off, and play is begun. At this time, the following key operations are possible. = All servo off , , = Repeated focus searching. When a disc is loaded, play is begun. = CLV-P, tracking on, sled on = CLV-A, tracking off, sled off = Fast-forward 200 track jump (during play only) = Fast-rewind 200 track jump (during play only) During and operation only, the current track number is displayed in the Track No. field of the display.
