1. DIFFERENCES BETWEEN THE µPD78F0701Y AND MASKED ROM VERSIONS
The µPD78F0701Y is a product provided with flash memory that enables writing, erasing, and rewriting of
programs without being removed from the board.
Table 1-1 shows the differences between the flash memory version (µPD78F0701Y) and masked ROM versions
(µPD780701Y and µPD780702Y).

Caution The flash memory versions and masked ROM versions have different noise immunity and noise
radiation characteristics. Do not use ES products for evaluation when considering switching
from flash memory versions to those using masked ROM upon the transition from preproduction
to mass-production. CS products (masked ROM versions) should be used in this case.
