µPD784031Y
16-/8-BIT SINGLE-CHIP MICROCONTROLLERS
The µPD784031Y is based on the µPD784031 with an I²C bus control function appended, and is ideal for
applications in audio-visual systems.
The µPD784031Y is a ROM-less version of µPD784035Y and 784036Y.
The functions are explained in detail in the following User’s Manual. Be sure to read this manual when
designing your system.
