Current consumption
Oscillation characteristics
Noise characteristics
Current consumption of Flash EEPROM versions are larger than
that of the Mask ROM versions, as it features voltage boosting. The
difference is larger in SLOW and HALT mode.
Matching evaluation of each version is necessary when these
versions are rotated for mass production.
Noise evaluation of each version is necessary when these versions
are rotated for mass production.
