Willem programmer

[golenam]

Hi
I bought a Willem programmer to read Microwire 93LC66A and it is impossible to read it. It appears all FF FF FF. I tried to disconnect the soic conector and it appears all FF FF FF's.
It looks like there is no connection at all. Somebody had same problems?
regards
:bawling:

I tried it many times without problems.
Sure wilem prog can read 93LC66 as well

[grinovsky]

before read,clic on ID ,if you see the right reference of your chip you can read/write

How you read it ? in-circuit or onboard ? For in-circuit willem not work with 93xx correct !

[golenam]

Yes, In-circuit. Do I need to desolder?

[eric paris]

hello
l think you must desolde it
look the datasheet some time the wiring is reverse on the eeprom

do you try with 93C86 In-circuit???

[ninja123]

never tried a 93c86 in circuit, but done 93lc66 loads of times, do almost daily, and 94c46 too, but must add power to your xprog first!
