DESCRIPTION
The
µ
PD780031AY, 780032AY, 780033AY, and 780034AY are members of the
µ
PD780034AY Subseries of the
78K/0 Series. This is a
µ
PD780034A Subseries product with an added multimaster-supporting I
2
C bus interface, and
is suitable for AV equipment applications.
A flash memory version, the
µ
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.
