DESCRIPTION
The
PD780232 is a member of the
PD780232 Subseries in the 78K/0 Series.
The
PD780232 Subseries consists of products that incorporate a VFD controller/driver for panel control.
A flash memory version, the
PD78F0233, that can operate within the same power supply voltage range as the
mask ROM version, 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.
