User’s Manual U16227EJ2V0UD376CHAPTER 23μPD78F0114TheμPD78F0114 is provided as the flash memory version of the 78K0/KC1.TheμPD78F0114 replaces the internal mask ROM of theμPD780114 with flash memory to which a program canbe written, erased, and overwritten while mounted on the board. Table 23-1 lists the differences between theμPD78F0114 and the mask ROM versions.Table 23-1.

When pre-producing an application set with the flash memory versionand then mass-producing it with the mask ROM version, be sure to conduct sufficientevaluations for the commercial samples (not engineering samples) of the mask ROM versions.
