The format of this data sheet has been redesigned to comply with the new identity guidelines of
NXP Semiconductors.
Legal texts have been adapted to the new company name where appropriate.
Section 6.6 “External RESET” , 1 st sentence: changed from “t W ” to “t w(rst) ”
Figure 10 “Write to register” : symbol changed from “t pv ” to “t v(Q) ”
Figure 11 “Read from register” :
– symbol changed from “t ph ” to “t h(D) ”
– symbol changed from “t ps ” to “t su(D) ”
Table 11 “Limiting values” :
– parameter description for V I/O changed from “DC voltage on an I/O” to “voltage on an
input/output pin”
– symbol/parameter changed from “I I/O , DC output current on an I/O” to “I O(LEDn) , output
current on pin LEDn”
Table 12 “Static characteristics” :
– title of this table changed from “DC characteristics” to “Static characteristics”
– descriptive line below table title: deleted “TYP at 3.3 V and 25 ° C” (this is moved to new
Table note [1] , with its reference at column heading “Typ”
– I stb Max value changed from “3.0 μ A” to “5.0 μ A”
– parameter description for symbol ? I DD changed from “additional standby current” to
“additional quiescent standby current”

Table 13 “Dynamic characteristics” :
– changed parameter description for f SCL from “operating frequency” to “SCL clock frequency”
– (old) symbols “t VD;DAT (L)” and “t VD;DAT (H)” merged to “t VD;DAT ” and added separate
conditions for LOW-level and HIGH-level
– symbol/parameter changed from “t PV , output data valid” to “t v(Q) , data output valid time”
– symbol/parameter changed from “t PS , input data setup time” to “t su(D) , data input set-up
time”
