Webb16 juni 2024 · "tHD:DAT", or data hold time, for I2C is defined from the low-threshold end of the falling edge of SCL (VIL = 30% of VDD), to the start of the falling or rising edge of SDA (70% or 30% of VDD). From the screenshot, it does seem like this time is > 300 ns and on the 600 ns range. It looks ok to me. Thanks and I hope this helps, Peng, Webbif using the HCNT/LCNT calculated in the core layer.
