M24512
16/24
Table 14. AC Characteristics (M24512 – 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. For M24512 devices whose package marking shows the process letter “A” t
W
(max) = 5ms whereas for M24512 devices whose
package marking shows the process letter “V” t
W
(max) = 10ms
