ELECTRICAL OPERATING CONDITIONS
Operating time: the circuit is designed to be able to operate continuously
Backup: no backup capability (standby) will be provided internally
Handling: inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally
safe, it is desirable to take normal handling precautions appropriate to handling MOS devices.
10 CHARACTERISTICS
VDDD = 3.3 V for the internal core and for the I/O pad section. Tamb = 0 to 70 °C; unless otherwise specied.
