8-BIT SINGLE-CHIP MICROCONTROLLERS

MOS INTEGRATED CIRCUIT

DESCRIPTION

The

PD780031AY, 780032AY, 780033AY, and 780034AY are members of the

PD780034AY Subseries of the

78K/0 Series. This is a

PD780034A Subseries product with an added multimaster-supporting I

C bus interface, and

is suitable for AV equipment applications.

A flash memory version, the

PD78F0034AY, that can operate in the same power supply voltage range as the mask

ROM version, and various development tools, are available.

Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before

designing.
