Current consumption, etc. differs.
Others
Noise immunity and noise radiation differ because circuit scale and mask layout differ.
Cautions 1. There are differences in noise immunity and noise radiation between the flash memory and
mask ROM versions. When pre-producing an application set with the flash memory version
and then mass-producing it with the mask ROM version, be sure to conduct sufficient
evaluations for the commercial samples (not engineering samples) of the mask ROM
version.
2. When replacing the flash memory versions with mask ROM versions, write the same code
in the empty area of the internal ROM.
