The previous batch of STC11F02 about 300 pieces, at least 100 pieces of could not be programmed, I try it by many methods but all failed .
Urgently I bought a batch of STC11F02E back, view the difference between the two data , I fought the STC11F02E has 2K EEPROM, but STC11F02 does not, it should be available, but still can not write into the program.
Pls help me what’s problem.
