Hi,Luciano

I have 05250SE as a code.

I bought them at the end of last year ( 2005 ) from FARNELL.

I've seen the errata giving an increasing EEPROM Writing time from 4 to 5.5 ms ...

may be, MPLAB didn't follow ...

something strange is I have to program it in 4 times ( ! ) to get 100% success

1) Erase all
2) Config words only( Ok only at second pass ...)
3) Program only
4) EEPROM only

setting to "Auto select" fails at each trail ... " Erase all at first" too
