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.

1. DIFFERENCES AMONG MODELS IN µPD784038Y SUBSERIES
The only difference among the µPD784031Y, 784035Y, 784036Y, 784037Y, and 784038Y lies in the internal memory
capacity.
The µPD78P4038Y is provided with a 128-Kbyte one-time PROM or EPROM instead of the mask ROM of the
µPD784035Y, 784036Y, 784037Y, and 784038Y. These differences are summarized in Table 1-1.
