    Hello,

    I think it's not a timing problem. I think the 8051 isn't that much faster than my 167 at 20MHz. I have worked with different Eeprom types and I've never had any problems with timing.

    I'm using a single NOP between setting the SCL pin and SDA pin. Wires between processor and Eeprom have to be short.

    Perhaps it would help if you watch the signals with an oscilloscope.
