DIFFERENCES FROM THE MASK ROM MODELS
This section explains the differences in functions (except for the Flash EEPROM block) between the E0C63P466
and the mask ROM models (E0C63454, E0C63458 and E0C63466).

q
Power Supply
Since the E0C63P466 is produced using the Flash EEPROM process, the characteristics are different from those
of the mask ROM models.
1) Operating voltage range
E0C63P466: 2.7 to 5.5V
E0C63454: 2.2 to 5.5V (Min. 1.8V when the OSC3 is not used)
E0C63458: 2.2 to 5.5V (Min. 1.8V when the OSC3 is not used)
E0C63466: 2.2 to 5.5V (Min. 1.8V when the OSC3 is not used)
