PRELIMINARY PRODUCT INFORMATION
1998
The
μ
PD780984, 780986, and 780988 are members of the
μ
PD780988 Subseries of the 78K/0 Series. These
microcontrollers are suitable for general-purpose inverter control.
Compared with the
μ
PD780964 Subseries, these microcontrollers provide expanded internal ROM and RAM
capacities and enhanced inverter control, timer, and serial interface.
A flash memory version, the
μ
PD78F0988, which can operate within the same power supply voltage range as the
mask ROM version, and various development tools are under development.
The following documents explain the functions in details . Be sure to read them before designing.
