– Section 2 “Features”, (old) 4th bullet item deleted

– Table 1 “Ordering information” modiﬁed

– Table 2 “Marking codes” modiﬁed

– Figure 2, Figure 3 and Figure 4 modiﬁed

– Table 6 “Register 0 - Interrupt Enable (IE) register bit description”, Table note [1] modiﬁed

– Table 8 “Register 1 - Control Register (B1:B0 = 01b) bit description”, Table note [1] modiﬁed

– Table 11 “Default Control Register values” modiﬁed

– Table 14 “Register 2 - Interrupt Status (ISTAT) register bit description”, Table note [1] modiﬁed

• (Old) Table 16 “Static characteristics (2.3 V to 3.6 V)” and (old) Table 17 “Static characteristics

(3.6 V to 5.5 V)” are merged.

• Table 16 “Static characteristics”, sub-section “Supply”:

– Istb (Typ) at condition VDD = 2.3 V to 3.6 V changed from “10 µA” to “30 µA”

– Istb (Max) at condition VDD = 2.3 V to 3.6 V changed from “100 µA” to “80 µA”

– Istb (Typ) at condition VDD = 3.6 V to 5.5 V changed from “10 µA” to “40 µA”

– Istb (Max) at condition VDD = 3.6 V to 5.5 V changed from “200 µA” to “100 µA”

• Table 16 “Static characteristics”, sub-section “Input SCL_MSTn; input/output SDA_MSTn

(upstream and downstream channels):

– for condition VDD = 3.6 V to 5.5 V, deleted IIL and IIH speciﬁcations (was in old Table 17)

• Table 16 “Static characteristics”, sub-section “Select inputs A0 to A3, INT_IN, RESET”:

– for condition VDD = 3.6 V to 5.5 V, ILI (Max) changed from “+50 µA” to “+1 µA” (from old

Table 17)

• Table 16 “Static characteristics”, sub-section “Pass gate”:

– for condition VDD = 3.6 V to 5.5 V, IL (Max) changed from +100 µA to +1 µA (was in old

Table 17)

• Figure 25 “Deﬁnition of RESET timing” modiﬁed:

– changed signal name from “LEDx” to “INTn”

– deleted “LED off”
