DATA SHEET
MOS INTEGRATED CIRCUIT
µPD789304, 789306, 789314, 789316
8-BIT SINGLE-CHIP MICROCONTROLLER
The µPD789304, 789306, 789314, and 789316 belong to the µPD789306, 789316 Subseries (for LCD drivers) in
the 78K/0S Series.
Flash memory versions (µPD78F9306, 78F9316) that can be operated using the same power supply voltage as
mask ROM versions are available, along with various development tools.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
