8-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD780021A, 780022A, 780023A, and 780024A 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, 780022AY, 780023AY, and 780024AY are the µPD780024A Subseries with a multimaster
supporting I2C bus interface, which makes them suitable for AV equipment.
Flash memory versions, the µPD78F0034A, 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.
