1. DIFFERENCES BETWEEN PD78P058F AND MASK ROM VERSIONS
identical functions to mask ROM versions ( PD78056F and 78058F) except the functions of PROM specifications and
of mask options for P60 to P63.
Note The RESET input sets the internal PROM capacity and internal expansion RAM capacity to 60 Kbytes and 1024

bytes, respectively.
The PROM version and mask ROM version differ in noise tolerance and noise emission. When
replacing a PROM version with a mask ROM version when switching from experimental production
to mass production, make a thorough evaluation with a CS version (not ES version) of the mask
ROM version.
