Post subject: | Pioneer IC (Chip) Datasheets ? |
Looking at some issues with a couple of Pioneer Players...and particularly focusing on Pioneer Mode Controller Chips....except the Service Manuals do not have much info on them...usually such commercial Chips have a readily available Datasheet. do such Pioneer Chip Datasheets exist ? were they ever provided to service technicians? |

They weren't really commercial ICs, they were internal ICs. Some service manuals show IC internals and full pinouts though. I have a few technical training manuals that go into a tad more detail for the players they were written for. All the information the tech needed in regards to ICs was in the service manual and service guide. |

Yes it would be nice if were some tech info to describe the process/steps of the micro chips... we have what we have! |

Check pages 76-78 of CLD-99 SM for mode control details. Pinout of IC is on page 69. From there you can look at the service guide here: CLD-D770 |

Many thanks for the info pointers C++ .... that info gives us more clues! It seems each Service Manual varies in the info you get.... I have been working on players CLD-2290/2090 and CLD-2590K where both cannot see Digital Tracks but also they have the same issue whereby a Microcontroller output should be high (5V) but isnt - on pushing the power button. |

I posted in your CLD-2290 thread. |
