______________________________________________________________________
Note 1:
All voltages are referenced to ground.
Note 2:
ISTBY specified for VCC equal 3.0V and 5.0V, SDA = SCL = VCC, and I/O0 = I/O1 = I/O2 = I/O3 = A0 = A1 = A2 = GND.
Note 3:
A fast-mode device can be used in a standard-mode system, but the requirement tSU:DAT > 250ns must then be met.
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 tRMAX + tSU:DAT = 1000ns
+250ns = 1250ns before the SCL line is released.
Note 4:
After this period, the first clock pulse is generated.
Note 5:
The maximum tHD:DAT has only to be met if the device does not stretch the LOW period (tLOW) of the SCL signal.
Note 6:
A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the VIH MIN of the SCL sig-
nal) in order to bridge the undefined region of the falling edge of SCL.
Note 7:
CB—total capacitance of one bus line in picofarads, timing referenced to 0.9VCC and 0.1VCC.
Note 8:
EEPROM write begins after a STOP condition occurs.
