8-BIT SINGLE-CHIP MICROCONTROLLER
The
碌
PD789322, 789324, 789326, and 789327 are
碌
PD789327 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
碌PD78F9328,
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鈥檚 manuals. Be sure to read them before
designing.
