10. Static characteristics
[1]
Typical limits at VDD = 3.3 V, Tamb =25 °C.
[2]
VDD must be lowered to 0.2 V in order to reset part.
[3]
Each I/O must be externally limited to a maximum of 25 mA and the device must be limited to a maximum current of 50 mA.
Table 13.
Static characteristics
VDD = 2.3 V to 5.5 V; VSS =0V; Tamb = 40 °C to +85 °C; unless otherwise specied.
