780021AY, 780022AY, 780023AY, 780024AY
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.

Notes 1. SDA0 and SCL0 are incorporated only in the µPD780024AY Subseries.
2. SI31, SO31, and SCK31 are incorporated only in the µPD780024A Subseries.
Cautions 1. Connect the IC (Internally Connected) pin directly to VSS0 or VSS1.
2. Connect the AVSS pin to VSS0.
Remark When the µPD780021A, 780022A, 780023A, 780024A, 780021AY, 780022AY, 780023AY, and 780024AY
are used in applications where the noise generated inside the microcontroller needs to be reduced, the
implementation of noise reduction measures, such as supplying voltage to VDD0 and VDD1 individually
and connecting VSS0 and VSS1 to different ground lines, is recommended.
