    Prom/eeprom

    I know, its not about caps..

    But, mabye someone can help anyway.
    When looking at the datasheet for an Atmel AT28C256 EEPROM (PLCC) it seems pin compatible with a normal OTP PLCC PROM. But, when using the EEPROM, my device is not working.
    Any ideas ??

    The AT28C256 has a different pin configuration to a normal OTP PLCC PROM.
    However, an SST27SF256 (many time programmable) is pin-compatible with a normal OTP PLCC PROM.
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

      check the voltage levels (supply and signal), they vary a lot between the different families.

        I'll look into the SST27SF256
