MOS INTEGRATED CIRCUIT

PD780232

8-BIT SINGLE-CHIP MICROCONTROLLER

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.
