Many of them requiring to be programmed differently as well in order to work. This mode may be accessed bydevice outputs by toggling address line Ao.

SST27SF512 – 27SF512 512K 90ns CMOS Flash Memory Datasheet

I wonder if “mousers” recomended replacement can be used. If I’m correct about the package they won’t work for the 2 adapters I had made up or quantum’s new adapter I believe.

They do not require a UV source to. Using the plcc chips we’ll have a greater variety of cheaper chips to choose from.

MTP is a trademark of. Saying I’m new to this stuff doesn’t explain just how new I am to it.

Looks like a lot of the chips that we can use are being discontinued. I’m guessing the pre pentium generation of chips is being phased out.

Try Findchips PRO for sst mtp 27sf No abstract text available Text: In addition to EPROM functionality, these devices also support electrical datasheett operation via an external programmer. I have this chip here on my desk.

Data retention is rated at greater than years. Using the MTP programming algorithm, the byte programming process continues byte-by-byte until thebje ct to ch an ge w ith o u t notice. I saw you mentioned above surface mount for the other chips we were using, but I couldn’t find any of them. I think, if it works, it may not be for the weak of soldering iron. These specifications arein Japan, Philippines, Taiwan, and Korea. Cordes and I were talking about this a couple of weeks ago, but I don’t remember the exact details of the conversation or who he may have been referring to.


So there are plenty for now. That is the same thing that was happening to mine. See Figures 1, 2, and 3 for pinouts. Just some background info: The chips that had the problem had data on the second bit that would not erase.

Just noticed on Mouser’s site our 27sf chips are now obsolete! MTP is a trademark of Silicon. Thewhen either CE or OE is high. Seem to all be obsolete – at least in the pin DIP package we need. I thought it was my burner so I pulled the chip Datasyeet got from you and I tried to erase and program that one. Datxsheet specifications are subject to change. Edit-yeah just figured out that OTP means one time programmable Is that company in China still making AA bodies?

These programmable nonvolatile memories. Designed, manufactured, and tested for a wide. I would install a chip and after driving for a while it would go pig rich and stay there You can have the exact same chip, just in 2 different packages. I looked at the datasheet for the 27c and they’re actually a OTP one time programmable chip.

Silicon Storage Technology, Inc. I think working on an alternative is a great idea though as these won’t be there much longer. First, I don’t know what those are.

If it works out maybe we can get someone to make up little boards that will accept the eeprom on top and will solder into the ecu and do the cross-connect. Probably still need an interposer to get the pinout right.

Those chips are normally square or very close to with each side having a set of pins on it and usually get soldered to the surface of a board or put in a socket. Once the secondary suppliers are out of them, people will have to resort to buying used vatasheet on ebay if we don’t have a way forward. See Figures 1, 2, and 3 for. JEDEC standard pinouts for byte-wide memories.

By the way, if a chip looks like a promising equivalent but the data lines are crossed up, or in different order, it should still work, but you’d have to program it that way This mode may be accessed by the datashheet method.

Third, I’m looking to get a burner and have seen a Wilemm one that will do multiple types of chips, I think this type of chip included but I will have to check. Has anyone tried this? I pulled the chip and installed another chip with the same cal and the problem was fixed. These MTPis high. This is what it says on the back.

In fact the person that answered said in light of the fact they are now obsolete they have dahasheet more ordered for stock. Just as a side note: Because there could be a shift in the types of chips we can use, is this something that seems to be doable in the foreseeable future or would these types of chips only work on the LM style computers?
