MOS INTEGRATED CIRCUIT
DESCRIPTION
The
µ
PD780021A, 780022A, 780023A, and 780024A are members of the
µ
PD780024A Subseries of the 78K/0
Series. Only selected functions of the existing
µ
PD78054 Subseries are provided, and the serial interface is enhanced.
The
µ
PD780021AY, 780022AY, 780023AY, and 780024AY are the
µ
PD780024A Subseries with a multimaster
supporting I
2
C bus interface, which makes them suitable for AV equipment.
Flash memory versions, the
µ
PD78F0034A, 78F0034B, 78F0034AY, and 78F0034BY, that can operate in the same
power supply voltage range as the mask ROM versions, and various development tools, are also available.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
