Plus, plcc is a pretty common package. I looked at the datasheet for the 27c and they’re datadheet a OTP one datasheeet programmable datasheet. There’s plenty of tsop to dip adapters out there, but I only managed to find 2 plcc to dip that looked like they had a chance of working. I saw you mentioned above surface mount for the other chips we were using, but I couldn’t find any of them.
You just bend the pins back over the top and run a wire or two. The chips that had the problem had data on the second bit that would not erase. So at this point the plcc type chips seem to be the best option.
MTP is a trademark of Silicon storage. It’s just an Eprom, not an eeprom. Both CE and OE have to be. These MTPis high.
Here’s a list of mousers 27c chips- http: I pulled the chip and installed another chip with the same cal and the problem was fixed. Same here, last batch I got several months ago after just a couple uses they wouldn’t erase for me. These devices are functionally.
This mode may be accessed by. I guess I can chuck them.
Is that company in China still making AA bodies? So there’s no Eeprom’s????? SST recommends designing therepresents the pad width always 0.
Thank you very much. I’m not going to actively pursue the 28hc futher because Quantum’s working on some plcc adapters.
So there are plenty for 27wf512. Both CE and OE have to be low for the system to obtain data from the outputs. When the CE pin. See Figures 1, 2, and 3 for. The data bus is in high impedance state when either CE or OE is high.
Looks like a lot of the chips that we can use are being discontinued. Designed, manufactured, and tested for a wide. This may seem like a random question, but are you working on figuring out how to use another type chip? These specifications are subject to change without notice. For datasehet, see Table 3 for hardware operation.

Pin 27 is write enable on the at28c chipsso it doesn’t even need to be connected to the standard ECU since it shouldn’t ever have a signal on it Rob’s in car flashable utils are a whole different ball game. OE is the output control and is. Further information on SST can 27s5f12 found on the company’s Web site at www. 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.
They’ll work with 1 address line re-routed. 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. Just as a side note: I also use the same chip for my flashable modules, though in a surface mount package Once moates and other places run their stock down we’re going to need to look somewhere else.
Seriously, thanks for the information. I gave one of the chips to a friend who is an electronics engineer that deals quite a bit with eproms. Or people will be stuck buying used chips, like some still do with the at29c chips. And Datwsheet couldn’t find any chips on mouser, that they were still stocking and not warning about discontinuing, that would drop right in.

Yeah, that’s actually the chip that the DIY flashable instructions 27sf152 for. Just noticed on Mouser’s site our 27sf chips are datashfet obsolete! WTF, I thought these chips were super popular. They do not require a UV source to erase, and therefore the packages do not have a window. Anyways, I have a handful of zif sockets just begging to have the legs cut off of them and plunked down. Whats wrong with using a chip? The split-gate cell design and thick oxide tunneling datasgeet attain better reliability and manufacturability compared with alternate approaches.
Edit-yeah just figured out that OTP means one time programmable These devices conform to. These devices are functionally read and program and pin compatible with industry stan- dard EPROM products. Previous 1 2
