PRELIMINARY PRODUCT INFORMATION
MOS INTEGRATED CIRCUIT
µPD789322,789324,789326,789327
8-BIT SINGLE-CHIP MICROCONTROLLER
The µPD789322, 789324, 789326, and 789327 are µPD789327 Subseries (designed for remote controller with on-
chip LCD) product in the 78K/0S Series.
In addition to an 8-bit CPU, they have on-chip hardware for a remote controller with on-chip LCD, Including a LCD
controller/driver, a serial interface, a key return signal detection circuit, and timers with carrier generator that can
easily output waveforms for infrared remote control.
The µPD78F9328, a product with on-chip flash memory which can operate on the same supply voltage as for
masked ROM products and various development tools are also under development.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
