PARAMETER
All voltages are referenced to ground.
I
A fast-mode device can be used in a standard-mode system, but the requirement t
This is automatically the case if the device does not stretch the LOW period of the SCL signal. If such a device does
stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line t
+250ns = 1250ns before the SCL line is released.
After this period, the first clock pulse is generated.
The maximum t
A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the V
nal) in order to bridge the undefined region of the falling edge of SCL.
C
EEPROM write begins after a STOP condition occurs.
