The
PD789101A, 789102A, and 789104A (
PD78910xA hereafter) are
PD789104A Subseries products of the
78K/0S Series.
The
PD789111A, 789112A, and 789114A (
PD78911xA hereafter) are
PD789114A 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.
A stricter quality assurance program (called special grade in NEC's grade classification) is applied to the
PD789101A(A), 789102A(A), 789104A(A) (
PD78910xA(A) hereafter), and
PD789111A(A), 789112A(A),
789114A(A) (
PD78911xA(A) hereafter), compared to the
PD78910xA and 78911xA, which are classified as
standard grade.
In addition, a flash memory version (
PD78F9116A) that can operate within the same power supply voltage range
as the mask ROM version, and a range of development tools are also being prepared.
Detailed function descriptions are provided in the following user's manuals. Be sure to read them before
designing.
