Description

The mPD780021A, 780022A, 780023A, and 780024A are members of the mPD780024A Subseries of the 78K/0 Series. Only selected functions of the existing mPD78054 Subseries are provided, and the serial interface is enhanced.

A flash memory version, the mPD78F0034A, that can operate in the same power supply voltage range as the mask ROM version, and various development tools, are available.
