#130532 - Incorrect Responding to: ???'s previous message |
It is possible to operate with I2C bus from 100Khz to 400khz as you know
incorrect, there is no minimum clock frequency, only a maximum and that is device dependent for some devices you can run from 0.0001Hz to 100kHz for some devices you can run from 0.0001Hz to 400kHz for some newer devices you can run from 0.0001Hz to 1MHz it's all in the datasheet for the device. If I remember correctly, the 24C32 is 100kHz, the 24C32A is 400kHz but DO check. http://www.standardics.nxp.com/literatur...n.2003.pdf is a 3 hour 'class' in IIC, I recommend it. Erik |
