The PD78F9026 is a PD789026 subseries product (for compact general-purpose devices) of 78K/0S series.
Besides an 8-bit CPU, it contains various peripheral hardware such as I/O ports, a timer, serial interface, and
interrupt control.
The PD78F9026 has a flash memory in the place of the internal ROM of the PD789022, 789024, 789025, and
789026. Data can be written to or erased from the flash memory of the PD78F9026 with the microcontroller
mounted on the printed wiring board.
Detailed information about function is provided in the following user's manual. Be sure to read it before
designing:
