描述 Description

The μPD78F9189 is NEW Subseries (small, general-purpose) in the 78K/0S Series. The μPD78F9189 replaces the internal ROM of the μPD789188 with 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.
