These devices are functionally read dqtasheet program and pin compatible with industry stan- dard EPROM products. OK, after looking at some datasheets I may have found 27sr512 answer. I’ve got no problem being the guinea pig, but I won’t bother if someone has done it and found out it didn’t work. Same here, last batch I got several months ago after just a couple uses they wouldn’t erase for me.

These devices are functionally.

Could that be a good, easy alternative? Many of them requiring to be programmed differently as well in order to work. Edit-yeah just figured out that OTP means one time programmable I saw you mentioned above surface mount for the other chips we were using, but I couldn’t find any of them. These MTP devices can be electrically erased. I’m going to have a test board made up anyways, but I’m just wondering if there’s demand for this sort of thing.

This mode may be accessed by.

Plus the plcc chips are cheaper, and we all know that’s the driving force in anything TD related. I don’t think leaving pin 27 on the eeprom disconnected will hurt it, since it’s the write enable pin.

I think, if it works, it may not be for the weak of soldering iron. Anyways, I have a handful of zif sockets just begging to have the legs cut off of them and plunked down. I looked at the datasheet for the 27c and they’re actually a OTP one time programmable chip.

I pulled the chip and installed another chip with the same cal and the problem was fixed. These specifications are subject to change without notice. Probably still dataasheet an interposer to get the pinout right. So, when the ecu has a signal it normally puts for address line 14 on pin 27 normally it needs to go to pin 1 instead.

I’m guessing the total additional height would be between. This mode may be accessed bydevice outputs by toggling address line Ao. If I’m correct about the 72sf512 they won’t work for the 2 adapters I had made up or quantum’s new adapter I believe. That seems to be the only pin that’s different between the at28 and at29 eeproms I actually checked vs the sst datasheet. These programmable nonvolatile memories.

But I guess if you’re already using them, that means the ecu won’t have a problem reading from them as long as that 1 address line is put in the right place. Further information on SST can be found on the company’s Web site at www. Just checking to datasheef if they would be of any use. Using the MTP programming algorithm, the byte programming process continues byte by byte until the entire chip KBytes has been programmed.

When the CE pin. This is what it says on the back. Anyone look at Futurlec? I am not sure of the difference, though. Also, 27sc512 everyone else here uses a willem I have one, but perfer my moates I doubt we’d go to something that couldn’t be burned with a willem, so you’re pretty safe there. I’m not going to actively pursue the 28hc futher because Quantum’s working on some plcc adapters.


Hopefully that stops some of the head scratching when PLCC is mentioned: Thewhen either CE or OE is high. So even if they were the right package and pinout, they’re worthless for anything other than 1 cal because you can’t erase and rewrite them.

See Figures 1, 2, and 3 for. SST recommends designing thedatashet the pad width always 0. It’s address line 14 that’s on pin 1 of the at28c type chips. They’ll work with 1 address line re-routed. Looks like a lot of the datashheet that we can use are being discontinued. Once moates and other places run their stock down we’re going to need to look somewhere else.

These devices will improve flexibility, efficiency. Data retention is rated at. What are we going to do when these run out?

Is that company in China still making AA bodies? The chips that had the problem had data on the 27df512 bit that would not erase.

SST used to do it, you could get a 27sf in a 28 pin dip or a 32 pin plcc.
