The problem was that the resistors I was using as pull-up resistors were in fact 1k not 2k. I changed them for 2k resistors and the problem disappeared.
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, WebbI2C only needs two signals (SCL for clock, SDA for data), conserving board real estate and minimizing signal quality issues. Most I2C devices use seven bit addresses, and bus speeds of up to 400 kHz; there’s a high speed extension …

Webb19 nov. 2024 · SDA must be stable for the entire HIGH period of SCL. SDA must be held for 300ns while SCL goes low. Saying "while" here seems a bit strange, but it's to emphasize the 0 + 300ns minimum needed for SCL transition back to low. Typically I believe the hold time will be (1/2*SCL period) + 300ns. blythewood chamber of commerce scWebbSDA Hold Time Intel® Agilex™ 7 Hard Processor System Technical Reference Manual ... 16.5.12.1.
