PD780232
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
µ
PD780232 is a member of the
µ
PD780232 Subseries in the 78K/0 Series.
The
µ
PD780232 Subseries consists of products that incorporate a VFD controller/driver for panel control.
A flash memory version, the
µ
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.
