DESCRIPTION  
The µPD780021A(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 µPD780021A,  
780022A, 780023A, 780024A, 780021AY, 780022AY, 780023AY and 780024AY (standard models) is applied (NEC  
classifies these products as “special” quality grade models).  
The µPD780021A(A), 780022A(A), 780023A(A), and 780024A(A) are members of the µPD780024A Subseries of  
the 78K/0 Series. Only selected functions of the existing µPD78054 Subseries are provided, and the serial interface  
is enhanced.  
The µPD780021AY(A), 780022AY(A), 780023AY(A), and 780024AY(A) are the µPD780024A Subseries with a  
multimaster supporting I2C bus interface, which makes them suitable for AV equipment.  
Flash memory versions, the µPD78F0034A and 78F0034AY, 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.
