Hello,
Our customer use TPS65910A1 + AM3352 with I2C SLAVE FAST MODE.
Then ,I got the following questions from my customer about I2C.
(1) I2C timing of I3, I4, I7, I8, I9
Could you please let me know the timing figure like the attachment?
Below figure is I2C manual from NXP.
(2) SCL/SCLSR_EN1 and SDA/SDASR_EN2 rise and fall time
TPS65910A1 has the min time of rise and fall time as 20+0.1xCL.
However, AM335x doesn't have the min time.
Our customer measured fall time of I2C by their board.
As a result, rise time is within charateristics but fall time is under 10ns.
Is this time problem ?
If yes please let me know the countermeasure.
Our customer I2C schematic is same with below user's guide.
