PD78F4218Y
16/8-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The
μ
PD78F4218Y is a product in the
μ
PD784218Y subseries in the 78K/IV series.
The
μ
PD78F4218Y has a flash memory in the place of the internal ROM of the
μ
PD784218Y. Data can be written
to or erased from the flash memory of the
μ
PD78F4218Y with the microcontroller mounted on a printed wiring board.
The
μ
PD78F4218Y is based on the
μ
PD78F4218 with an I
2
C bus control function appended, and is ideal for
applications in audio-visual.
The functions are explained in detail in the following user’s manuals. Be sure to read this manual when
designing your system.
