How about 28 C 64, or 28[C] or 28[C] This meant they could not work down to DC the lowest freq of write cycle possible. Also, 18 bucks to ship it is ridiculous.

Pls tell how to make this, as where to write this program which type of computer is need.?? By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use 28664 the website is subject to these policies.

Would be good to clarify by changing the DC bit. Having to use what is in stock at a local store would be extremely limiting, even in the United States where we have lots of big electronics stores.

The Willem type has the dual advantages of being less expensive and will take an external power supply. If you have the counters increment automatically after each programming pulse, you will have to debounce the “program” button. That’s the main point here. If the cycle limit is intended to guard against stray write events, engineering it to be usable with systems that run at slow clock speeds should have been trivial and would have improved usability.

Select a forum Absolutely yes If you don’t set things up correctly with both the hardware and the software you might end up with the computer trying to talk to the EEPROM at the same time the EEPROM is trying to talk to the computer, in that case they might short each other out. If the device rejects any write cycles that are excessively long, that may help guard against erroneous write operations in cases where a system operation gets disrupted e.

I do not think there ever was an official product called the Willem programmer.

I could be wrong on this, you’ll need to check. Anyway, it is cheap and works well.
