I have 3 chips of SST 49LF080A and 2 will ID properly, although the model of the chip doesn't appear with the Device Code. I don't remember where I got the device IDs from but my chip is ID BF and the Manufacturer is BF.

I'm doing some testing and I just want to make sure that I'm reading the proper information. The first thing I'm to check is VCC-32 checked on it's own. I have set the switches as per the HW Test tab and I think my issues is at least partially tied to the VCC-32 pin. When I check the box and I check...

Thanks Ezo! I will give it a shot. Do I test with or without a chip? I would be more inclined without a chip as who knows what random pin voltages will do, not me.

I posted a reply to that thread with the translated English from translate.google.com.

Again, problems arise when programming the chip on the adapter BIOS FWH / LPC It is easier than to ask another question, I recommend to read the old topics by WebSite Search (search-fwh) in my forum and Viillema.

I'm wondering if you have any ideas for this issue? I'm to the point where I think I may need a new programmer which is $50 down the drain.

I used the test HW feature of the programmer but it seems that everything is coming back fine. I generally get 4 voltage readings on various pins. I get 12v83 on pin 1, 0v on other pins, 4v8 on some pins and 3v5 on others.

Some pins only get voltage when Vpp(pin 1) is checked.

The picture for this product looks identical to the one I have. http://www.keeelectronics.com/catalog/product_info.php?cPath=22&products_id=49 I have sent you a few emails with the manual and picture I took of the programmer. Manual is 8MB+ zip of html manual distributed with programmer on CD Pictur...

Are you getting valid ID reply ? Nothing seems to work. Chip data read even seems to get dirty data randomly, although it is reading some data correctly, such as the last blocks having the ROM date. 0x0FFFF5 to 0x0FFFFC always reads 11/30/09. Clean softly PLCC32 chips sideward. I used alcohol to cl...

Hello all, I'm having difficulties programming an SST 49LF080A. I've been googling around and I haven't found any information that has helped. I am able to program 6 chips that belong in the PLCC32 socket, however I can't program any of the 3 chips that belong in the FWH/LPC socket. Does anyone have...
