8-BIT SINGLE-CHIP MICROCONTROLLERS
The
µ
PD789121, 789122, and 789124 are
µ
PD789124 Subseries products of the 78K/0S Series.
The
µ
PD789131, 789132, and 789134 are
µ
PD789134 Subseries products of the 78K/0S Series.
Besides an 8-bit CPU, these microcontrollers incorporate a variety of hardware such as I/O ports, timers, a serial
interface, A/D converters, and interrupt control.
In addition, a flash memory version (
µ
PD78F9136) that can operate within the same power supply voltage range
as the mask ROM version, and a range of development tools are also being developed.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
