Refer to the data sheet of individual products.
Note The µPD78F0034B can use one channel (serial interface SIO30) as a handshake mode.
The µPD78F0034A cannot use a handshake mode.
Remark
The operating frequency ratings of the µPD78F0034B and the expanded-specification products of the
mask ROM versions of the µPD780024A, 780034A Subseries are the same. The operating frequency
ratings of the µPD78F0034A and the conventional products of the mask ROM versions of the
µPD780024A, 780034A Subseries are the same.
