Can't find these IC!

03-16-2010, 03:01 PM

I planned on reworking the amplifiers for my '96 Voyagers speaker setup, but I can't find information on the IC's. The main one is an NEC 9547A and is a 12-pin SIP or whatever. The other is an unbranded BH715H1 (an 8-pin SIP) which leads to the rear speakers, I believe and is used for low low frequency production.

Anybody, have any rare datasheets? lol!

Re: Can't find these IC!

Are there 2 rows of numbers on the chips? The 9547A sounds like 1995, 47th week, which would make sense in a 1996 vehicle.

ENCONTRAR DATOS DMI EN EL CHIP BIOS IDEAPAD5 15ITL05 / FIND DMI DATA ON IDEAPAD5 15ITL05 BIOS CHIP

by danielgerman681

Hi, Im trying to find the area on the chip that contains all of my laptops information, but I havent found it. The laptop won't turn on anymore. I was updating the BIOS, and it was supposed to reboot itself, but it wouldnt turn back on. I ve tried every possible solution, every alternative on Lenovo forums, everywhere; I ve taken it to technicians, and no one has been able to fix it. I've already read the chip that contains the BIOS (Winbond 25Q128JSVQ) and searched for my laptops data, but they're nowhere to be found. I only find scribbles and lines of text indicating errors. Has anyone had a...

Where to find a very small fpc connector 0.3mm between 2 pins ?

by corrize

Hello, I search this connector (oxydated).
It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?

Do you know how to find this connector please ? What is the exact name for find it ?
