Electrical specifications

Current consumption, etc. differs. (Refer to each product data sheets.)

Others

Noise immunity and noise radiation differ because circuit scale and mask layout differ.

Caution There are differences in noise immunity and noise radiation between the flash memory version and

mask ROM version. 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 evaluation for

commercial samples (not engineering samples) of the mask ROM version.
