PD78F9177, 78F9177Y
8-BIT SINGLE-CHIP MICROCONTROLLER
MOS INTEGRATED CIRCUIT
The
µ
PD78F9177 and
µ
PD78F9177Y are
µ
PD789177, 789177Y Subseries (small, general-purpose) in the 78K/0S
Series.
The
µ
PD78F9177 replaces the internal ROM of the
µ
PD789176 and
µ
PD789177 with flash memory, while the
µ
PD78F9177Y replaces the ROM of the
µ
PD789176Y and
µ
PD789177Y 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.
