The µ PD78F0034AY can be used as the flash memory version of the µ PD780024AY Subseries.
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 (CS) (not engineering samples (ES)) of the mask ROM versions.
