Why is so8 test clip causing read errors with 93C56 eeprom (TL programmer)? | All About Circuits
Jan 10, 1. Nov 5, 19 0. I am trying to read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer. When using the so8 adapter in the zif socket it works perfectly. However when I use the test clipit is giving me read errors on every other bit. The errors are consistent and seem to happen with every bit value except FFFF.
The test clip works fine when writing data also. This is what it should look like: This is what it looks like when using the clip: And here are a few other bit values, spliced together to save space In every case except FFFFthe even numbered bits 0,2,4, I have also tried 8dip versions of this eeprom in this same programmer and they never give errors so I must assume it is the clip.
I have checked the pins of the clip and 93c65 are all correct and if they weren’t it shouldn’t be able to write to the eeprom If this were a serial port I might try slowing down the bitrate, but this programmer seems to have no settings at all. The reviews for this clip dont mention this problem, and it is sold edprom the same company that sells the programmer. Btw the chip is not soldered to anything, it is attached only to the test clip Chinese manufacturer of the programmer: Jan 10, 2.
Apr 30, 1, My best guess is a flaky connection on one of the wire to pin connections at the back end of the clip.
Jan 11, 3. Two different of those same chip were tested However Using another 93c56 from another manufacturer gives no similar error. I would still like to know why it is able to write but not read?
Please do not take anything for granted, the answer maybe dead simple but I’m just not eeprim it. Why is using a battery causing my ATtiny85 to malfunction?
