10 / 12 page FM24CL64B - 64Kb 3V I2C F-RAM (Automotive Temp.) Rev. 1.1 June 2011 Page 10 of 12 AC Test Conditions Equivalent AC Test Load Circuit Input Pulse Levels 0.1 VDD to 0.9 VDD Input rise and fall times 10 ns Input and output timing levels 0.5 VDD Diagram Notes All start and stop timing parameters apply to both read and write cycles. Clock specifications are identical for read and write cycles. Write timing parameters apply to slave address, word address, and write data bits. Functional relationships are illustrated in the relevant datasheet sections. These diagrams illustrate the timing parameters only.
