Table 13. AC Characteristics (M24Cxx-W)
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. Previous devices bearing the process letter “L” in the package marking guarantee a maximum write time of 10ms. For more infor-
mation about these devices and their device identification, please ask your ST Sales Office for Process Change Notices PCN MPG/
EE/0061 and 0062 (PCEE0061 and PCEE0062).
