Function, Parameter/Code
Description and Application Notes
Refer to iC-TW28 datasheet release B1, 2016.
Table 128: Notes on chip functions regarding iC-TW28 chip release X.
iC-TW28 W
No.
Function, Parameter/Code
1
Power Supply Rise Time
2
Elec. Characteristics:
Items 902, 903
Description and Application Notes
Extending the power-on reset by RC components at pin xRST is recommended for
all designs (see Fig. 10 and 11). If pin xRST is directly connected to VDD, VDD
rise time (from 0 V to 3.3 V) should be no less than 40 µs.
The specified short-circuit current limits can be exceeded at low/high temperatures.
