DESCRIPTION
The
m
PD78070A is a limited-function product from which the internal ROM of the
m
PD78078 subseries has been
removed. Through interchangeable external ROM, program maintenance can be performed easily. Besides a high-
speed, high-performance CPU, this microcontroller has an internal RAM, I/O ports, 8-bit resolution A/D con-
verter, 8-bit resolution D/A converter, timer, serial interface, real-time output port, interrupt control, and various
other peripheral hardware.
Detailed information about product features and specifications can be found in the following documents. Be sure
to read the following documents before starting design.
