CXP1042Q
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. 64 pin QFP (Plastic)
Functions · Key inputs of up to 16 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 16 tunes · REMOTE Enables input using NEC format remote control devices with modifiable custom codes · 10key Direct tune selection using keypad; selects tune on memory input (remote control only) · Syncro Synchronization input and processing ·×2 Double speed playback · Battery detection When portable mode selected, there is battery detection function · Simple adjustment of tracking gain/balance Recommended Combinations · RF amplifier/servo signal processor CXA1782B · Digital signal processor CXD2507A/2508A · Pickup mechanism KSL 2101 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; 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.
