The
μ
PD78F9418 is
μ
PD789417 sub-series product (LCD driver) of the 78K/0S series.
This microcontroller features an 8-bit CPU, LCD controller/driver, I/O ports, timers, a serial interface, A/D
converters, a comparator, and interrupt control circuits.
The
μ
PD78F9418 replaces the internal masked ROM of the
μ
PD789415,
μ
PD789416, and
μ
PD789417 with flash
memory, which enables the writing/erasing of a program while the device is mounted on the board.
The functions of this microcontroller is described in the following user’s manuals. Refer to these manuals
when designing a system based on this microcontroller.
