DESCRIPTION
The
PD780021A(A), 780022A(A), 780023A(A), 780024A(A), 780021AY(A), 780022AY(A), 780023AY(A) and
780024AY(A) are products to which a quality assurance program more stringent than that used for the
PD780021A,
780022A, 780023A, 780024A, 780021AY, 780022AY, 780023AY and 780024AY (standard models) is applied (NEC
Electronics classifies these products as "special" quality grade models).
The
PD780021A(A), 780022A(A), 780023A(A), and 780024A(A) are members of the PD780024A Subseries of
the 78K/0 Series. Only selected functions of the existing
PD78054 Subseries are provided, and the serial interface
is enhanced.
The
PD780021AY(A), 780022AY(A), 780023AY(A), and 780024AY(A) are the PD780024A Subseries with a
multimaster supporting I2C bus interface, which makes them suitable for AV equipment.
Flash memory versions, the
PD78F0034B(A) and 78F0034BY(A), 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.
