D78F9418 Product details
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 µPD78F9418 replaces the internal masked ROM of the µPD789415, µPD789416, and µPD789417 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 microcontroll.
