[br]Hello, I bought a GQ 3X Programmer and I�m trying to read and write one 93C66BZ eeprom (SOIC 8) which is ONBOARD (I need to do it in this way beacuse i can�t desoldering the device). I�m using this tool: http://www.mcumall.com/comersus/store/comersus_viewItem.asp?idProduct=4406

Step by Step this is what i�m doing:

- look for this model at the device selection and I choose 93C66B (16 BIT EEPROM).

- I try to read the Device.

- The buffer is full of FFFFFFF.

I don�t know what is wrong. Could anybody help me? What is the right way step by step to read this eeprom? I send several photos show the situation:

1st - usig tool ONBOARD

mithranthir	Posted - 02/08/2013 : 06:24:54 I have desoldered the chip and try to read and write it and it works. Thank you very much.
Bad_Ad84	Posted - 02/06/2013 : 04:30:22 Not all chips can be programmed on board - it depends very heavily on the circuit design. You should remove the chip and read/write it that way if on board isnt working.
