CXP1021Q
System Controller for Compact Disc Players
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)
Functions · Key inputs of up to 20 keys is possible through matrix scanning. The following functions can be selected by setting their respective keys. , , · PLAY/PAUSE/PLAY PAUSE keys · STOP key , · SKIP key; on memory input, this becomes the tune selection key , · Fast forward key; speed differs during PLAY and PAUSE · Repeat One tune or all tunes repeat · OPEN/CLOSE Loading function (when deck type device is selected) ·A B A B repeat function · SHUFFLE Shuffle (random) function · PROG Program; up to 21 tune memory, can indicate remainder · REMAIN Indicates single tune or all tunes remaining, up to 31 tunes · INTRO Fixes introscan at 10 seconds · AUTO Sets auto space at 4 seconds · MUSIC calendar Can display up to 20 tunes · REMOTE Enables input using NEC format remote control devices with modifiable custom codes · 10key Direct tune selection using keypad (remote control only) · Syncro Synchronization input and processing ·×2 Double speed playback · Battery detection When portable mode selected, there is battery detection function · Built-in test mode Built-in test mode facilitates CD player auto diagnostics · INDEX Index search (remote control only) · Pitch +, pitch , pitch OFF Pitch control key for playback with varying speed · External control output Used for on/off of the voice canceller Recommended Combinations · RF amplifier · Servo signal processor · Digital signal processor · Pickup mechanism Structure Silicon gate CMOS IC

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.
