SUBSERIES
The only difference among the
μ
PD784214A, 784215A, 784216A, 784217A, and 784218A lies in the internal
memory capacity.
The
μ
PD784214AY, 784215AY, 784216AY, 784217AY, and 784218AY are models with the addition of an I
2
C bus
control function.
The
μ
PD78F4216A, 78F4216AY, 78F4218A, and 78F4218AY are provided with a 128 KB/256 KB flash memory
instead of the mask ROM of the above models.
These differences are summarized in Table 1-1.

Note
The internal flash memory capacity and internal RAM capacity can be changed using the internal memory
size switching register (IMS).
Caution 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 on the
commercial samples (not engineering samples) of the mask ROM version.
