Note: 1. For a reSTART condition, or following a Write cycle.
2. Sampled only, not 100% tested.
3. To avoid spurious START and STOP conditions, a minimum delay is placed between SCL=1 and the falling or rising edge of SDA.

Note: 1. For a reSTART condition, or following a Write cycle.
2. Sampled only, not 100% tested.
3. To avoid spurious START and STOP conditions, a minimum delay is placed between SCL=1 and the falling or rising edge of SDA.
4. This is preliminary data for M24Cxx-xx3 and M24Cxx-Rxx6
5. 10ms write time is offered on the standard device. 5ms write time is offered on new products bearing the Process Identification letter
“W” on the package, as described in Table 23.
