SST replacement chip for Winbond chip (Bios for A8N32-SLI)
Hello,
My Asus A8N32-SLI motherboard came with a Winbond W39V080APZ BIOS CHIP. I think this SST chip could replace it: http://www.sst.com/products.xhtml/pa...16/SST39LF200A Not 100% sure though. Bye, Skybuck. |

I found a picture on AMD zone:
http://www.amdzone.com/pics/motherbo...2-SLI-2D-L.jpg It seems more like that the chip used in the picture is one of these: http://www.sst.com/products.xhtml/serial_flash/49/ That does not mean that the other could not be compatible Bye, Skybuck. |

I also found a picture of another motherboard:
http://forums.2cpu.com/showthread.php?t=80902&page=2 It has the following bios chip: http://www.sst.com/products.xhtml/se...49/SST49LF080A Analysis of the AMD zone picture suggests a match So this chip is probably compatible Going to investigate the PDF document Kinda funny how the site mentions internet appliances etc. Bye, Skybuck. |

What do they mean with:
Lead and Lead-free. Do they mean the metal ? Is their a health risk during normal operation... like lead particles in the air or so ? Or is this only of concern during a fire/meltdown ? Or is it only of concern when throwing it in the waste basket ? Bye, Skybuck. |

For the *consumer* mainly the last. That's just one reason of many that they're beginning to outlaw throwing electronics devices of any size in the trash.

Another plus for recycling is the *reclaiming* of many valuable metals such as copper and gold (and yes, lead and cadmium too). Electrolysis works wonders there. One thing *hard* to reclaim is the lead in CRT glass, used as a barrier for the soft radiation emitted. However, luckily, such thick glass envelopes are declining rapidly in popularity in favor of flat-panel displays for both TV and computer monitors, that just don't NEED such thick leaded-glass envelopes any more. -- _____ / ' / â„¢ ,-/-, __ __. ____ /_ (_/ / (_(_/|_/ / _/ _ |

Bye, Skybuck. Is the chip in a 32 pin PLCC package ? The web page says: "48-lead TSOP packages and 48-ball TFBGA packages" Does it have an LPC interface ? It looks to have only a parallel interface. So the chip isn't even close. Paul |

Small, actually, as the lead doesn't vaporize much at barely liquid temperatures; but not nonexistent either. The fumes *do* solidify into minute particles though; which are easily breathed. I have read many times that below 500 degrees C, the vapour presure of lead is not high enough to be a hazard. I have not heard any claims that the fumes from soldering contain hazardous amounts of lead. What IS potentially hazardous is the fumes from the burning flux that accompanies soldering. The flux for lead-free soldering supposedly results in more dangerous fumes because it is a more active flux and the temperature is higher, but then you weren't supposed to breathe it anyway.... Or is this only of concern during a fire/meltdown ? Mostly during: A. Production. B. Scrapping. C. Yes, fire/meltdown. Production these days have mostly switched almost completely to non tin/lead solders. Scrapping old electronics though is a problem when they end up in landfills where the lead can leach out over time. This is the supposed reason for RoHS, which implies that they do not believe that they will succeed in collecting the waste under the other expensive scheme that they have introduced (WEEE), or alternatively, they might be wanting to redefine "burning circuit boards" as "recycling", or perhaps they recycle them as a "means of filling unwanted holes in the ground". I'm not sure which it is. Or is it only of concern when throwing it in the waste basket ? For the *consumer* mainly the last.

But they still allow you to put hundreds of kilograms of lead on the roof of your house, in direct contact with rainwater! Somehow it makes the lead on a non-compliant 0402 component seem insignificant. Chris |

Are you talking about all the nails with the lead "mushroom" caps to seal against water ingress? As far as I can tell, those are not readily available anymore, being replaced by rubber washed-headed nails instead. |
