The μPD78F9177  is μPD789166 Subseries (small, general-purpose) in the 78K/0S Series.
The μPD78F9177 replaces the internal ROM of the μPD789166with flash memory.
Because flash memory allows the program to be written and erased electrically with the device mounted on the
board, this product is ideal for the evolution stages of system development, small-scale production and rapid
development of new products.
Detailed function descriptions are provided in the following user’s manuals.  Be sure to read them before
designing.
