The device is optimized for use in many indus- trial and commercial applications where low-power and low-voltage operations are essential. The AT93C46/56/66 is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP, 8-lead TSSOP, and 8-lead dBGA2 The AT93C46/56/66 is enabled through the Chip Select pin (CS) and accessed via a three-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK). Upon receiving a Read instruction at DI, the address is decoded and the data is clocked out serially on the DO pin. The Write cycle is completely self-timed, and no separate Erase cycle is required before Write. The Write cycle is only enabled when the part is in the Erase/Write Enable state. When CS is brought high following the initiation of a Write cycle, the DO pin outputs the Ready/Busy status of the part. The AT93C46/56/66 is available in 2.7V to 5.5V and 1.8V to 5.5V versions.

When using the so8 adapter in the zif socket it works perfectly. Jan 10, 2.
Why is using a battery causing my ATtiny85 to malfunction? But what is the format of the data? Just as the title states I wish to flash a 93c56 EEPROM in my jeep cherokee gauge cluster because my old gauge cluster has malfunctioned and the new one will have incorrect millage on the odometer. I would still like to know why it is able to write but not read?
Apr 30, 1, The reviews for this clip dont mention this problem, and it is sold by the same company that sells the programmer. My best guess is a flaky connection on one of the wire to pin connections at the back end of the clip.
I just wonder if moving the chip might be a solution.
And if so how would I go about doing this? This is why we test Posted by nsaspook in forum: Your name or email address: Posted by nimaid in forum: If you had the appropriate sw from the manufacturer I bet you could do eprom via the OBDII connector – but I also bet they’re not telling you how! Do you already have an account?
Why is so8 test clip causing read errors with 93C56 eeprom (TL866 programmer)?
I have checked the pins of the clip and they 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. Is there a connector next to this chip which does this?
Btw the chip is not soldered to anything, it is attached only to the test clip Chinese manufacturer of the programmer: And here are a few other bit values, spliced together to save space In every case except FFFFthe even numbered bits 0,2,4, Ill see what I can do about separating that chip. Why is so8 test clip causing read errors with 93C56 eeprom TL programmer?
It may be cheaper and less risky to go to a Cherokee dealer and get him to do it Digital Signal Processing is the mathematical manipulation of an information signal, such as audio, temperature, voice, and video and modify or improve them in some manner.
This is what it looks like when using the clip: Quote of the day. Not to mention so many people in the jeep community have arduinos and would benefit from this. No clue how do I go about getting this info? Nov 5, 19 0.

I am trying to read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer. I just figured why not try with my arduino and learn a thing or two. I’ll see if I can find my old bitbasher – but given the datasheet you could figure it out. Eepron, my password is: This is what it should look like: I’ll look into that cloning. Embedded Systems and Microcontrollers.
Writing to the eeprom isn’t too hard if you have access to the pins.
But not that easy. Use this tutorial to get your FPGA development environment setup and eeproj the tool set and basic development process. Jan 11, 3. The test clip works fine when writing data also.
It won’t be easy, as eperom don’t want crooks ‘clocking’ the mileage. Two different of those same chip were tested However Using another 93c56 from another manufacturer gives no similar error. I have also tried 8dip versions of this eeprom in this same programmer and they never give errors so I must assume it is eepprom clip. You May Also Like: Please do not take anything for granted, the answer maybe dead simple but I’m just not seeing it.
If Eeprmo do go about pulling the code, is there a circuit that needs setup and any pre written code for this? The errors are consistent and seem to happen with every bit value except FFFF.

No, create an account now. Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by cdsJan 10, I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher.
However when I use the test eeproomit is giving me read errors on every other bit. There must be a procedure to clone the new cluster from the old.
