CHAPTER 1 GENERAL
1.2 Features of 78K/0 Series
The 78K/0 series is a collection of 8-bit single-chip microcontrollers ideal for commercial systems.
The
μ
PD78054 and 78054Y subseries are provided with peripheral hardware functions such as an A/D converter,
D/A converter, timer, serial interface, real-time output port, and interrupt function.
The
μ
PD78064 and 78064Y subseries are provided with peripheral hardware functions such as an LCD controller/
driver, A/D converter, timer, serial interface, and interrupt function.
The
μ
PD78078 and 78078Y subseries are based on the
μ
PD78054 and 78054Y subseries with a timer added and
the external interface function reinforced.
The
μ
PD78083 subseries is provided with peripheral hardware functions such as an A/D converter, timer, serial
interface, and interrupt function.
The
μ
PD78098 subseries is based on the
μ
PD78054 subseries with an IEBus controller added.
The
μ
PD780018 and 780018Y subseries are versions of the
μ
PD78078 and 78078Y subseries (serial interface
with time division transfer function) with an improved serial interface and a limited number of functions.
The
μ
PD780058 and 780058Y subseries are low-EMI noise versions of the
μ
PD78054 and 78054Y subseries
(serial interface with time division transfer function), with an improved serial interface.
The
μ
PD780308 and 780308Y subseries are versions of the
μ
PD78064 and 78064Y subseries with increased ROM
and RAM with an improved serial interface.
The
μ
PD78058F, 78058FY, 78064B, 78075B, 78075BY, and 78098B subseries are low-EMI noise versions of the
μ
PD78054, 78054Y, 78064, 78078, 78078Y, and 78098 subseries.
The
μ
PD78070A and 78070AY subseries are the ROM-less versions of the
μ
PD78078 and 78078Y subseries.
The
μ
PD78054Y, 78064Y, 78078Y, 780058Y, 780308Y, 78058FY, 78075BY subseries and
μ
PD78070AY are
provided with I
2
C bus control function instead of the SBI function of the
μ
PD78054, 78064, 78078, 780058, 780308,
78058F, 78075B subseries and
μ
PD78070A.
In addition, one-time PROM, EPROM, or flash-memory models that can operate at the same operating voltage
as the mask ROM models and that are ideal for early and small-scale production of the application system are also
available.
The block diagram and function outline of each series is shown on the following pages.
